The 6 Co-Teaching Models: What They Are, When to Use Them, and Why Variety Matters

Think back to the class that put you to sleep in high school. There was probably a teacher at the front of the room, talking at you every single day. Same format. Same energy. Same experience.

No small-group support. No one checking whether you understood before moving on. No variety in how the content was delivered. Just one person and one approach, repeated until the bell rang.

That is one-teacher instruction at its most limited, and it is exactly what co-teaching is designed to change.

Co-teaching is not just two adults sharing a classroom. It’s a genuine partnership between a general education teacher and a special education teacher who share responsibility for the same students. The smaller student-teacher ratio helps, but the bigger benefit is what becomes possible when two teachers combine their expertise, content knowledge from the gen ed teachers, instructional strategies and knowledge of student needs from the special educator, to create something neither could build alone.

There’s countless ways to organize how you and a co-teacher run the classroom. But, there are six commonly recognized co-teaching models that give that partnership a practical structure. Each one creates a different classroom setup, a different student experience, and a different opportunity for instruction. The teachers who use co-teaching most effectively are not picking a favorite and running it every day. They are matching the model to the lesson, rotating throughout the week, and using that variety on purpose, because the variety itself is part of what makes an inclusive classroom work.

Key Takeaways

• Co-teaching has six distinct models. Each serves different instructional purposes and works best in different situations.
• No single model is best. Effective co-teachers rotate models based on the activity, learning goal, and student needs rather than defaulting to whatever is most comfortable.
• Variety in grouping and instructional format supports student engagement and gives students with disabilities more ways to access instruction throughout the week.
• Co-teaching most often falls apart because of unclear roles and insufficient co-planning time, not because the teachers aren’t trying hard enough.

Why the Model You Choose Matters

Co-teaching is often described as two teachers sharing one classroom. That description skips the most important question: what is each teacher actually doing and why?

Each co-teaching model creates a different classroom structure and a different opportunity for targeted, individualized instruction. When you choose a model based on the learning goal, what students need, and what the activity calls for, co-teaching delivers on its promise. When you default to whatever feels easiest, it’s usually more frustrating than helpful.

The model should match the kind of learning students need that day. Be it small group discussion, new content with a clear instructional lead, or targeted small group instruction, co-teaching gives flexibility that you can’t quite get with just one teacher. It makes differentiated instruction more practical in an inclusive setting, because the structure of the lesson changes without removing students from the shared classroom.

The big key is in the variety that a co-taught classroom can provide. Like all students, those with diverse learning needs benefit from changes in format, group size, and the type of support available to them. If every day in the co-taught classroom looks identical, engagement drops and the students who most need flexible instruction miss out.

Rotating through co-teaching models throughout the week is also useful professional development for both teachers. It builds fluency, deepens the co-teaching relationship, and keeps the collaboration from quietly collapsing into one teacher leading while the other follows.

The 6 Co-Teaching Models

These six models are instructional options, not a ranking. Each one has a useful purpose when the structure matches the lesson or goal.

No matter which structure you’re using, the best co-teaching relationships make it hard to tell who is the special and who is the general education teacher. In all of the following descriptions, teachers should practice switching up who does what role within the model and working with all students.

1. One Teach, One Observe

What it is:

One teacher leads whole-class instruction while the other systematically observes and collects data. They may be observing an individual student, a group, instructional patterns, or behavior. The observing teacher is not helping students in the moment. They are watching intentionally, with a defined purpose and a structured way to record what they see. It might be ABC data or frequency data focused on student engagement, but the point is to actually walk away with data you can review and base decisions on.

Benefits:

This model produces genuinely useful information through structured data collection. The observing teacher can track frequency counts on a specific behavior, document which students are engaging and which are drifting, record whether accommodations are being implemented consistently, or gather baseline data for an IEP goal. Teaching is really demanding, so being able to just observe while the class is run by a co-teacher can give much stronger and more reliable data.

Drawbacks:

This approach only works when the observation is planned and purposeful. Walking around without a clear data collection goal is not this model. Before the lesson, both teachers need to agree on the purpose of the observation and specifically what will be observed.

When to use it:

At the start of the year when you need baseline data on new students. When a student’s behavior or progress needs closer examination. When you want to evaluate whether a specific instructional strategy or accommodation is working in practice. When you need FBA data and the behavior occurs during whole-class instruction. When there’s a whole-class behavior or engagement issue that needs addressing.

How often to use it:

Sparingly, when you need quality data. Great data just needs a sample, not an entire class period every day. Taking 15 minutes a few times a week can be very useful without spending all of your time observing.

2. One Teach, One Support (AKA One Teach, One Assist)

What it is:

One teacher leads whole-class instruction while the other circulates, monitors behavior, and actively helps students who need clarification, prompting, or additional support in the moment.

The supporting teacher is not just observing. They are moving through the room, checking in with students, redirecting behavior, answering questions, and helping students get unstuck before the lesson moves on without them.

Teachers should rotate who is in the main instructional role and who is supporting. And they’re not just supporting students with IEPs. All students have the benefit of the supporting teacher.

Benefits:

This is the easiest co-teaching model to implement, as it requires the least co-planning. It works well when one teacher has significantly stronger content expertise, and it is genuinely useful during independent practice when a second adult moving through the room makes a real difference for students who get stuck.

Drawbacks:

This is the most commonly misused model in co-teaching, and the most important one to watch carefully. The supporting teacher can gradually slide into functioning like a paraprofessional, following around specific students, or just managing behavior without ever delivering instruction. If this is the only model running in your co-taught classroom, it can be a waste of resources.

A special education teacher brings expertise in instructional strategies, student needs, and differentiated instruction, not just classroom management. A classroom where one teacher always leads and the other always supports is not a co-teaching partnership in any meaningful sense. This model belongs in a rotating toolkit, not as the permanent arrangement.

When to use it:

During direct instruction of new content when one teacher has significantly stronger content knowledge. During independent practice when circulating support genuinely serves students. As a starting point while the co-teaching relationship is still being built, with the explicit goal of adding other models throughout the year.

How often to use it:

This is a model that can be used often, but for only a portion of the class time. It’s great for lectures, when one teacher is providing the content, but it shouldn’t last the full class period.

3. Parallel Teaching

What it is:

The class splits into two groups of roughly equal size and both teachers deliver the same content simultaneously to their respective groups. Each group gets a smaller student-teacher ratio and more opportunity for interaction, participation, and direct feedback.

Benefits:

Parallel teaching significantly reduces the number of students each teacher is working with at one time, without removing anyone from the room. Students get more chances to ask questions, more speaking time during discussions, and more immediate feedback on their work. Because both teachers are delivering the same content, collaborative planning is more manageable, you are building one lesson together rather than two separate ones.

Drawbacks:

Both teachers need to coordinate carefully so both groups cover the same content at a similar pace. The room can get noisy, which matters for students with auditory sensitivities or attention needs, but don’t let that stop you from giving it a try. It’s usually more manageable than teachers expect. You also need enough physical space to run two simultaneous lessons without constant interference. Agree in advance on essential questions, key examples, and how you will check for understanding before splitting the group. The two lessons should look the same and have the same learning outcomes.

When to use it:

Review sessions where a smaller group dramatically changes the quality of conversation. Discussion-based activities where every student needs more speaking time than a full class allows. Practice sessions where a tighter ratio means faster feedback and more individualized attention.

How often to use it:

Often, especially for review and practice after you’ve already taught new skills.

4. Station Teaching (AKA Centers Teaching)

What it is:

Students rotate through stations with different activities and learning objectives. Typically, three stations are used: two teacher led stations, and a third set up for independent or collaborative student work. However, there are many other ways to organize the centers. Students move through stations during the class period, and each station can use a different format for present and practice material, so students have a variety of ways to engage: reading, discussion, hands-on practice, writing, or listening.

Benefits:

Station teaching is one of the highest-engagement models in the co-teaching toolkit. Movement, clear routines, varied modalities, and small group instruction create a classroom that feels active and lively while still being organized. Both teachers have active, distinct instructional roles at their station. Students with diverse learning needs get small-group instruction, more direct teacher contact, and varied formats that support access in ways a single whole-class lesson cannot.

This structure also supports differentiated instruction naturally. Groups can work on different entry points or levels of support while moving toward the same learning goal. IEP goals can be built into the small group work, and students can work in diverse small groups to reduce stigmatizing those with disabilities. Students also don’t have to go through every station the same way. Activities could vary with each group at teacher led stations and independent centers.

Drawbacks:

This model requires preparation, though the planning load can be more balanced when each teacher takes ownership of specific stations and materials. If you don’t have shared planning, you can plan your stations independently as long as your aligned on the learning objectives for each station.

Transitions can be challenging for students with behavioral needs or significant difficulty shifting activities. Teachers need to take the time to explicitly teach movement and station expectations and clearly define what the independent work will be each day before you expect students to manage themselves independently.

When to use it:

Can be used for teaching new content in small groups, practice with lots of feedback, and even for assessments that aren’t just paper-pencil. Lessons can naturally include several formats, like games, independent reading and writing, and explicit instruction all in one lesson. Any time small group instruction would meaningfully change the student experience. Reading, listening, writing, and hands-on tasks are all strong station formats.

How often to use it:

Frequently, as much as everyday as long as the station activities are updated and meaningful. Centers teaching is great for creating clear routines for a portion of the day where students know what to expect and planning can become easier with clear systems for each station.

5. Alternative Teaching

What it is:

One teacher works with the majority of the class on the main lesson while the other works with a small group on something different. Usually, this group is working on pre-teaching, re-teaching, or targeted instruction tied to IEP goals. The small group stays in the room, this is push-in small group instruction, not a pull-out. Which means the small group can include any student, not just those with IEPS, so all students learn more.

Benefits:

Alternative teaching allows for intensive, targeted specially designed instruction within the inclusive setting. The special education teacher can deliver IEP goal work, pre-teach vocabulary before a complex unit, or re-teach content after assessment data reveals gaps without removing students from their general education classroom or their peer community. It’s a big opportunity for what’s known as incidental benefit, which refers to the added learning that students without disabilities get when they’re in an inclusive classroom.

Drawbacks:

The biggest risk with this model is stigmatization. If the small group is always the same students, always the students with IEPs, always the students who are behind, it becomes visibly and socially separating in a way that undermines the purpose of inclusive education. Groups should rotate and serve different purposes across the week. Sometimes the group needs re-teaching. Sometimes it needs enrichment. Sometimes it is a mixed group working on a specific skill. The goal is that no student is always separated for the same reason.

When to use it:

Pre-teaching vocabulary or background knowledge before a complex unit. Re-teaching after data shows specific students did not master a concept. Targeted IEP goal work that requires focused, individualized attention. Any situation where a small group, not always the same group, would benefit from a different instructional approach than the rest of the class is receiving.

A really fun way to use it is to offer a different activity or even extra support and allow students to self-select that option. For example, the whole class is given an assignment with one teacher rotating around the room for support and the other teacher holds an open small group for anyone who wants more help.

When to use it:

Frequently, even everyday. Alternative teaching can be a quick 5-minute review of vocabulary while everyone else is doing a daily warm up. It’s very flexible and can be done on the fly if needed in the moment.

6. Team Teaching

What it is:

Both teachers share the instructional lead simultaneously, moving fluidly through the lesson together. Both contribute to direct instruction, both respond to student questions, and both hold equal authority in the room. There is no lead teacher and no support teacher. There are two teachers delivering one lesson together.

Benefits:

Team teaching is the most collaborative and educationally rich model when it is done well. Students with diverse learning needs experience two experts in the room at the same time, both actively teaching and both available to respond. It normalizes both teachers as equally credible, meaning students are less likely to see the special education teacher as “the helper” when both adults are visibly and equally driving instruction. When the co-teaching relationship and co-planning time are genuinely in place, this model can be powerful to watch.

Drawbacks:

Team teaching requires the highest level of mutual trust, content knowledge, and comfort with each other’s teaching styles. It cannot be improvised or faked. Both teachers need protected co-planning time to agree on who will introduce ideas, model thinking, ask questions, monitor understanding, and respond to student misconceptions before the lesson begins.

If the co-teaching relationship is new, this model will feel uncomfortable. If co-planning time is not protected, this model is really hard to make work. It is something to work toward deliberately and not something to expect on the first day you share a classroom.

When to use it:

Once the co-teaching relationship is established, co-planning time is genuinely protected, and both teachers are comfortable sharing the lead fluidly, you can use this model everyday. Discussions, Socratic seminars, complex modeling, and lessons where two perspectives authentically enrich the content are all natural fits.

Matching the Model to the Activity

The point isn’t to always use one model or to cram as many models in as possible. It’s about matching the needs of the lesson and students to a model that makes sense.

Here is a simple framework for deciding which model to reach for:

• Introducing brand-new content → One Teach One Support or Team Teaching
• Reviewing or practicing content → Parallel Teaching or Station Teaching
• Targeted IEP goal work needed → Alternative Teaching or Station Teaching
• Need data on a student or the group → One Teach One Observe
• Building the co-teaching relationship → Start with One Teach One Support (changing roles periodically), work toward Team Teaching

These models are not a hierarchy where some are better than others. They’re all tools in a toolkit.

A week of strong co-teaching might look like parallel teaching on Monday during a review activity, alternative teaching on Wednesday to pre-teach vocabulary before a complex reading, station teaching on Thursday for practice and application, and one teach one observe on Friday when you need focused data on a student who has been struggling. Co-teachers can also use different models within one lesson. This is what makes the inclusive classroom genuinely different from a classroom where two adults happen to occupy the same space.

Switching models also resets student attention and supports engagement in a way that repetition cannot. When the format changes, students interact with different peers and different instructional approaches. For students with diverse learning needs, that variety in grouping and modality is not just engaging, it is instructionally necessary.

When Co-Teaching Is Not Working

While there’s a lot of research that shows co-teaching is powerful for all students, there’s still challenges and the truth is that co-teaching fails often. It almost never fails because the teachers are not trying hard enough. There’s just a lot of barriers to this level of collaboration.

No co-planning time.

If you are walking into a co-taught lesson without knowing what you are doing or why, you’re likely going to feel ineffective. Co-planning time is a prerequisite for effective co-teaching. Bring it to your administrator as a student outcomes issue and a compliance concern, not as a personal request. Lesson planning for a co-taught class requires both teachers, and that time has to be protected.

Unclear roles.

Both teachers need to know their role before the lesson starts. Before the lesson, decide on roles and the purpose of the model you’ll use. Who will lead, who will collect data, which students need additional support, and how you will know whether the model worked? Just understanding your own and your partner’s role, will make the lesson go much better.

One teacher functions as a paraprofessional.

If the special education teacher is always the one circulating and supporting and never the one instructing, the arrangement is not co-teaching in any meaningful sense. This pattern usually develops gradually, no one officially decides it, but it becomes the path of least resistance. Once you notice it, choose one upcoming lesson where both teachers will have a clearly defined instructional role and start building from there. It won’t change overnight. You’ll have to build up this relationship overtime.

Relationship issues.

Co-teaching requires trust, and trust takes honest conversation. Different teaching styles, different expectations around lesson planning, different comfort with classroom management, these are all worth talking about directly before they become resentment. If you have had the conversation and things are not improving, that is a situation that needs administrative support. Teachers should not be expected to silently absorb a co-teaching arrangement that is not functioning.

Final Thoughts

Co-teaching done well is one of the most powerful things that can happen in an inclusive classroom, for students with disabilities and for every other student in the room. Two teachers, two areas of expertise, and a shared commitment to making the lesson work for everyone.

Done poorly, it is just two adults occupying the same space while one wonders what they are supposed to be doing.

The difference is the intentionality of knowing the six models, choosing the right structure for the activity, and rotating throughout the week so students get variety, not just repetition. Co-planning before the lesson instead of improvising during it and building the co-teaching relationship slowly is how Team Teaching eventually becomes possible.

You do not have to have it all figured out on day one. Start with the model that fits today’s lesson, and keep building from there.

Frequently Asked Questions

What is the most effective co-teaching model?

There is no single most effective model to prioritize using all the time. The effectiveness depends on what you are teaching, what students need, and what the activity calls for. The strongest co-taught classrooms rotate through several models across the day and week rather than defaulting to one. If you are looking for a starting point, One Teach One Support is the easiest to implement while you are building the co-teaching relationship, and Alternative Teaching tends to deliver the most targeted specially designed instruction once you are comfortable with the structure.

How often should co-teachers switch models?

There is no required frequency, but a useful target is two or three different models across a week. Look at your lesson plan and decide which structure fits the activities you’ll be using. The rotation often happens naturally once you are thinking about it that way rather than defaulting to whatever feels most comfortable or trying to make a specific model fit.

What do I do if my co-teacher only wants to use one model?

Have a direct conversation about what co-teaching is supposed to look like and why variety matters for student outcomes. If your co-teacher prefers one familiar routine, bring a specific suggestion for one upcoming lesson rather than asking for a complete overhaul. Starting concrete is always easier. If the special education teacher is functioning as a paraprofessional every day, that is a legitimate concern and worth bringing to administration if the conversation does not shift anything. If you want help explaining the co-teaching models, this free co-teaching model reference guide has scripts you can borrow to start the conversation.

What is the difference between One Teach One Observe and One Teach One Support?

They look and sound similar from the outside but serve completely different purposes. One Teach One Support means the second teacher is actively helping students in the moment. They’re prompting, redirecting, and answering questions. One Teach One Observe means the second teacher is systematically collecting data with a structured tool and a specific purpose. Before the lesson, be explicit with each other about which one you are doing and why.

Can co-teaching work without co-planning time?

Honestly, not well. You can manage with minimal planning time when using One Teach One Support and the supporting teacher is experienced and flexible. But the models that deliver the most instructional value, like Team Teaching, Station Teaching, and Alternative Teaching, depend on genuine co-planning. If you do not have protected co-planning time, advocate for it. It is a prerequisite, not a perk.

How do special education teachers and general education teachers divide lesson planning responsibilities?

A useful starting point: the general education teacher leads on content and curriculum, and the special education teacher leads on instructional strategies, accommodations, and IEP goal integration. In the strongest co-teaching partnerships, those roles blend more than they divide, as both teachers bring their expertise to one shared plan that accounts for content, access, student needs, and grouping together. The goal is one lesson built through shared responsibility, not two separate contributions stapled together. However, it takes time to build the systems and trust you need to get to the true co-teaching partnership. In the meantime, models like One Teach One Assist, Alternative Teaching, and Centers or Station Teaching can lesson the load while still providing a lot of benefits to students.
