An inclusion classroom is a general education classroom in which students with disabilities learn alongside nondisabled classmates for most or all of the school day, with the special education, related services and supplementary aids and services in their IEPs delivered in that room. “Inclusion” is not a term defined in the Individuals with Disabilities Education Act (IDEA): the legal requirement is the least restrictive environment, under which students with IEPs are educated with nondisabled peers to the maximum extent appropriate and removed from regular classes only when education there, with supplementary aids and services, cannot be achieved satisfactorily (20 U.S.C. 1412(a)(5); 34 CFR 300.114). This guide covers the law, staffing models, supports, an example, a comparison of settings, 2024-25 data and research.

Executive Summary
In the 2024-25 school year, 68.1% of the 7.6 million students ages 5 (in kindergarten) through 21 served under IDEA Part B were inside the regular class 80% or more of the day, the federal measure closest to inclusion, according to the U.S. Department of Education’s Office of Special Education Programs (OSEP).
A seat in a general class is only the start. Inclusion works when instruction is delivered in the room, teachers are supported and placement is decided student by student.
Key Takeaways
- Inclusion is a practice, LRE is the law: IDEA requires the least restrictive environment, not “inclusion.”
- Services travel to the student: the IEP’s instruction and supports are delivered in the general class.
- Several models exist: co-teaching, in-class support, consultation, paraprofessional and itinerant support.
- Supports come before removal: supplementary aids and services must be considered first.
- Research is favorable but mostly non-experimental, so the instruction matters as much as the setting.
What Is an Inclusion Classroom?
An inclusion classroom is a general education class that students with and without disabilities attend together, where the specially designed instruction and supports in each IEP are provided inside the class.
Students follow the grade-level curriculum with accommodations, and modifications where the IEP calls for them. Labels vary: inclusion class, co-taught class, in-class support or, in New York, integrated co-teaching. What counts is what the IEP states: the instruction, its provider, minutes and location (34 CFR 300.320(a)(4) and (a)(7)). IDEA allows special education to be conducted “in the classroom” and other settings (34 CFR 300.39(a)(1)); here, that classroom is the general one.
Inclusion and the Law: What IDEA Requires
IDEA requires the least restrictive environment (LRE): each student is educated in regular classes with supplementary aids and services unless the IEP team finds that education there cannot be achieved satisfactorily (34 CFR 300.114).
“Inclusion” does not appear as a placement term in IDEA or its Part B regulations (our search of 20 U.S.C. 1400 et seq. and 34 CFR Part 300 as in force in 2026). The Department of Education calls the LRE provisions “a strong preference, not a mandate,” for regular classes (71 Fed. Reg. 46585, 2006), decided case by case “rather than by the child’s category of disability” (46586). IDEA’s findings tie more effective education to ensuring that “special education can become a service for such children rather than a place where such children are sent” (20 U.S.C. 1400(c)(5)(C)). The rules and the continuum of placements are in our guide to the least restrictive environment.
Some states define the word. Florida requires districts to use “inclusion” for education in a general education regular class “reflecting natural proportions and age-appropriate heterogeneous groups,” with the student a valued member of the class and teachers given support (s. 1003.57(1)(a)2., Florida Statutes, 2026); see exceptional student education.
Inclusion, Integration and Inclusive Education
In United Nations usage, “inclusive education” means changing the school so that every student can learn in it, while “integration” means placing students with disabilities in mainstream classes and expecting them to adjust.
The UN Committee on the Rights of Persons with Disabilities draws that line in General Comment No. 4 (2016): integration places students in mainstream institutions “with the understanding that they can adjust to the standardized requirements of such institutions,” while inclusion “involves a process of systemic reform” of content, methods and structures; placement without such changes “does not constitute inclusion.” The United States signed the Convention on the Rights of Persons with Disabilities in 2009 and has not ratified it (UN Treaty Collection), so IDEA’s LRE rule is the binding standard in U.S. public schools.
Inclusion Classroom Models
Schools deliver special education inside general classes through five common arrangements, often combined for one student.
| Model | What it looks like | How one state or IDEA writes it |
|---|---|---|
| Co-teaching | A general and a special education teacher share one class all period | New York integrated co-teaching: at most 12 students with disabilities unless a variance applies, a special and a general education teacher at minimum (8 NYCRR 200.6(g)) |
| In-class support (push-in) | A special educator teaches a student or small group during the lesson | New Jersey in-class resource program: at most 8 students with disabilities in elementary, 10 in secondary (N.J.A.C. 6A:14-4.6(n)) |
| Consultation | A special educator plans with the general teacher, who adapts instruction | New York consultant teacher services, direct or indirect: at least 2 hours a week per student, at most 20 students per teacher (8 NYCRR 200.1(m), 200.6(d)) |
| Paraprofessional support | A trained aide assists under a teacher’s direction | Paraprofessionals “appropriately trained and supervised” may assist (34 CFR 300.156(b)(2)(iii)) |
| Itinerant services | A specialist travels between schools, such as a teacher of students who are deaf or hard of hearing | “Itinerant instruction” with regular class placement (34 CFR 300.115(b)(2)) |
See co-teaching models for the six ways two teachers share a class, the resource room for short pull-out blocks, and paraprofessional training for the aide’s role.
Supports That Make Inclusion Work
An inclusion classroom works when the IEP’s aids, instruction and supports for staff are delivered in the room.
- Supplementary aids and services provided in regular classes and other settings (34 CFR 300.42), such as IEP accommodations.
- Specially designed instruction: adapting “the content, methodology, or delivery of instruction” (34 CFR 300.39(b)(3)), in small groups during the lesson.
- Lesson design: universal design for learning builds options into every lesson, and high-leverage practices such as explicit instruction apply in general classes.
- Supports for school personnel written in the IEP (34 CFR 300.320(a)(4)); each teacher must know their responsibilities (34 CFR 300.323(d)).
- Lunch, recess and clubs with nondisabled peers (34 CFR 300.117).
What an Inclusion Classroom Looks Like: An Example
From the door, an inclusion classroom looks like any other; the difference is who teaches what, to whom, in each block. This original example of a fictional third-grade class of 24 students, five with IEPs, is one to adapt.
| Block | What happens | Adults |
|---|---|---|
| Reading, 90 minutes | Mini-lesson for all, then stations; the special educator teaches decoding to a group of four, including Leo | Two co-teachers |
| Math, 60 minutes | Same lesson for all; Ana uses a number line and fewer problems, as her IEP states | General teacher, after a weekly 30-minute consultation |
| Science, then lunch | Lab in mixed groups; Sam follows a visual checklist and eats with his class | General teacher; paraprofessional at transitions |
Inclusion Classroom vs Resource Room vs Self-Contained Classroom
The three settings differ in where instruction happens and for how much of the day: in the general class, partly in a small group, or mostly in a separate special class.
| Feature | Inclusion classroom | Resource room | Self-contained classroom |
|---|---|---|---|
| Where instruction happens | General class all or most of the day | General class, plus part of the day in a separate room | Separate special class most or all of the day |
| Who teaches core subjects | General teacher, with a special educator co-teaching or supporting | General teacher; the special educator teaches targeted skills | Special education teacher, often with paraprofessionals |
| Group size | The whole class | Small groups (New York: at most 5 per teacher) | Small class capped by state rules (New York: 15 or fewer) |
| IDEA wording (34 CFR 300.114-300.115) | Regular classes with supplementary aids and services | Supplementary services “such as resource room” with regular class placement | “Special classes” |
| Closest OSEP environment, 2024-25 | Inside the regular class 80% or more (68.1%) | 80% or more, or 40% to 79% (14.8%), by minutes | Less than 40% (12.5%) |
| Texas setting code | 40, mainstream | 41 or 42, resource room/services | 43 or 44, self-contained, regular campus |
OSEP counts time in the regular class, not program names, so the match is approximate; Texas codes come from TEA’s 2026-27 data standards. See the self-contained classroom guide.
Inclusion Data for 2024-25
In 2024-25, the share of students inside the regular class 80% or more of the day varied widely by disability category.
| Category (ages 5 in kindergarten to 21) | Regular class 80% or more of the day |
|---|---|
| Speech or language impairment | 89.0% |
| Specific learning disability | 78.8% |
| Other health impairment | 72.5% |
| Emotional disturbance | 58.2% |
| Autism | 40.7% |
| Multiple disabilities | 24.6% |
| Intellectual disability | 21.0% |
| All categories | 68.1% |

What the Research Says About Inclusion
Studies published from 2013 to 2021 generally link more time in general education with better academic outcomes, though most designs cannot rule out that stronger students were included.
- Time and achievement: among more than 1,300 students ages 6 to 9, more hours in general education were strongly related to higher reading and math scores (Cosier and colleagues, 2013).
- Meta-analysis: across 40 studies, students with general learning difficulties in inclusive settings had better cognitive outcomes (d = 0.35) and similar psychosocial outcomes; the authors discuss selection effects (Krämer and colleagues, 2021).
- Extensive support needs: in 15 matched pairs, children included 80% or more of the day progressed more in communication, literacy and numeracy (Gee and colleagues, 2020).
- Classmates: a review found mostly positive or neutral academic effects in lower grades, neutral or negative ones in later grades, and social benefits (Kart and Kart, 2021).
Funding and Staffing
IDEA Part B funds may pay for services and aids provided in a regular class under an IEP “even if one or more nondisabled children benefit” (34 CFR 300.208(a)(1)). Staffing is harder: 45 states reported special education teacher shortages in 2024-25 (Learning Policy Institute, 2026).
Common Mistakes District Leaders Make
- Placing without supports. A seat without the IEP’s services is not inclusion.
- Writing “inclusion” as the service instead of the instruction, minutes, provider and location.
- Equating inclusion with co-teaching and ignoring the other models.
- Letting a paraprofessional become the teacher.
- Scheduling co-teachers without common planning time.
- Deciding by category or building instead of by each IEP (34 CFR 300.116).
Recommended Actions
- Define your inclusion models in writing, with what each requires.
- Build common planning time into the master schedule first.
- Audit IEPs for in-class services with minutes, provider and location.
- Train general educators on accommodations, UDL and their students’ IEPs.
- Review Indicator 5 data by campus and category, starting with autism and intellectual disability.
Questions District Leaders Should Ask
- Which inclusion models do our campuses use, and who chose them?
- Do our IEPs show instruction delivered in general classes, with minutes?
- How many inclusion sections does each special educator support?
- Were supports tried with data before last year’s moves to more restrictive settings?
Frequently Asked Questions
What is an inclusion classroom?
An inclusion classroom is a general education class where students with disabilities learn with nondisabled classmates for most or all of the day, and the instruction and supports in their IEPs are delivered in the room, by a co-teacher, a special educator, a consultant or a paraprofessional. Its legal basis is IDEA’s least restrictive environment rule, 34 CFR 300.114.
What is inclusive education?
Inclusive education means students with disabilities learn in the same schools and classes as their peers, and the school adapts content, teaching and structures so all can take part. The UN Committee on the Rights of Persons with Disabilities says inclusion involves “a process of systemic reform.” In U.S. public schools, the legal standard is IDEA’s least restrictive environment.
What does inclusion mean in special education?
It means delivering a student’s special education and related services inside general education classes rather than in a separate room or school. IDEA does not define the word; it requires removal from regular classes only when education there with supplementary aids and services cannot be achieved satisfactorily, a decision the IEP team makes for each student.
What is the difference between integrated and inclusive education?
Integration places students with disabilities in mainstream classes and expects them to adjust to the existing program; inclusion changes the program, teaching and supports so every student can learn there. The UN Committee on the Rights of Persons with Disabilities says placement without structural changes “does not constitute inclusion.”
What are the benefits of an inclusion classroom?
Studies link more time in general education with higher reading and math achievement for students with disabilities, and a 2021 meta-analysis of 40 studies found a small to medium cognitive advantage in inclusive settings for students with general learning difficulties. For classmates, a 2021 review found academic effects mostly positive or neutral in lower grades, neutral or negative in later grades, and social gains. Most studies are not randomized.
What are high-leverage practices for inclusive classrooms?
They are core teaching practices for students with disabilities, defined by CEC and the CEEDAR Center, such as collaboration, using data and explicit instruction. High Leverage Practices for Inclusive Classrooms (second edition, Routledge, 2022) applies them mainly to students with mild to moderate disabilities in general classrooms. Our guide to high-leverage practices covers the current 22 practices.
Is an inclusion classroom the same as a general education classroom?
Yes, as a setting: an inclusion classroom is a general education class, taught to grade-level standards, that includes students with IEPs. The label usually signals planned support, such as a co-teacher or regular consultation, but what each student receives is set by the IEP.

Conclusion
An inclusion classroom is a way of delivering special education, not a program name: in the general class, with the supports and instruction written into each IEP. Districts that define their models, protect planning time and check what each student receives turn placement in general classes into real inclusion.

Join the 2027 Special Education Pilot
Inclusion gives students more time with grade-level content, but the practice they need on IEP goals still has to fit between whole-class lessons, and two adults can reach only so many students in a period. Telo AI is being adapted for students with IEPs: patient, 1-on-1 practice aligned to each student’s IEP goals and pace, which frees teachers for small-group and individual work. We are inviting districts to shape it with us in a 2027 pilot.
