How-To Strategies
BENEFITS
Key Benefits for Students w/Disability
- Stronger growth in reading and math and more likely to pursue education or employment after high school.
-
Learning alongside peers gives students access to grade-level content, a wider range of instructional approaches, and higher expectations.
-
Inclusive placements are associated with fewer absences and fewer serious behavior incidents.
-
Being in general education allows more opportunities to practice communication, cooperation, and conflict resolution and to form meaningful friendships.
-
Avoiding segregation reduces stigma and social isolation, and students often report higher confidence and a more positive self-concept.
Benefits for Students without Disabilities
-
Learning daily with peers who have diverse needs reduces fear of difference and promotes more accepting, prosocial attitudes.
-
Show stronger communication skills, collaboration, and conflict-resolution abilities.
-
Classmates can act as peer models, tutors, or collaborators, which can deepen their own understanding and responsibility.
-
Gains in self-esteem, a stronger sense of belonging, and more developed ethical principles such as fairness and responsiveness to others’ needs.
Benefits for Classrooms and Schools
-
Bring special educators, therapists, and specialists into the general classroom, which can raise instructional quality for everyone.
-
Inclusive classrooms show fewer disruptions, stronger norms of caring, and more cohesive communities.
-
Inclusion and mainstreaming support legal and ethical commitments to educate students in the most typical setting.
Long-term Outcomes
-
Students who spend more time in general education have better postsecondary education and employment outcomes.
-
Stronger social networks and community participation. Inclusive school experiences support the development of friendships and social capital. link
HOW TO
Foundational Conditions
-
Clear vision and policies for inclusion. Schools articulate inclusion as the default, connect it to LRE and equity, and spell out expectations.
-
Leadership and scheduling that prioritize inclusion. Admins build master schedules around inclusive placements, protect common planning for co-teachers, and allocate paraprofessionals and related services into gen ed instead of pull-out by default.
-
Ongoing, job-embedded PD. Teachers get concrete training and coaching in co-teaching, UDL, behavior supports, and IEP implementation.
Instructional Design and Delivery
- Teachers plan lessons with multiple means of engagement, representation, so that grade-level content is accessible.
-
Align instruction to IEP goals with progress monitoring.
-
Flexible grouping and varied assessment. Station teaching, small groups, performance-based tasks, and multimodal assessments.
Collaboration and Staffing
-
Strong co-teaching partnerships. Share planning, instruction, and assessment using models like station, parallel, and team teaching, rather than “one teaches, one helps.”
-
Intentional use of paraprofessionals. Paras are trained to promote independence, scaffold access, and support peer interaction.
-
Related service providers (SLPs, OTs, behavior specialists) push in when possible and co-plan supports that can live in classroom routines.
Classroom Climate and Behavior Supports
-
Consistent expectations and tiered supports reduce exclusionary discipline and make classes manageable for diverse learners.
-
Culture of belonging and high expectations. Teachers explicitly teach prosocial norms, model respect for differences, and communicate that all students are capable.
-
Predictable routines with visual and organizational supports. Visual schedules, clear procedures, and structured transitions.
Family and Student Voice
-
Active family engagement in placement and planning. Families are treated as partners in decisions, share expertise on their children, and receive transparent communication.
-
Student agency and self-advocacy. Students are taught to understand their strengths and needs, use accommodations, and participate in IEP or goal-setting discussions. link
CHALLENGES
System and Resource Challenges
-
Insufficient funding and staffing. Schools often lack enough special educators, paraprofessionals, related service providers, and access to specialized materials.
-
Overcrowded classes and limited time. Large class sizes and packed schedules make differentiation, co-planning, and individualized support difficult to sustain.
-
Buildings, classrooms, and transportation may not be fully accessible or adaptable for students with diverse physical, sensory, or behavioral needs.
Teacher Capacity and Workload
-
Many general educators report feeling underprepared for disability-specific strategies, behavior supports, and accommodation/modification decisions.
-
Managing diverse needs, IEP requirements, and progress monitoring on top of core instruction can contribute to burnout and reduced self-efficacy.
-
When expectations for general vs. special educators, paraprofessionals, and related service providers are unclear, tasks fall through the cracks or are duplicated.
Co-Teaching and Classroom Practice
-
Without shared planning and clear models, special educators become aides, and students do not get the full benefit of two teachers.
-
Fixed pacing guides and standardized assessments can clash with the need to adapt content, process, and products for diverse learners.
-
Teachers may struggle to implement proactive supports, leading to increased disruptions, reliance on removal, or informal exclusion within the room.
Attitudes, Beliefs, and Relationships
-
Some educators and families still believe students with disabilities belong in separate settings, or view them as “someone else’s responsibility.”
-
Social prejudice or lack of structured social support can leave students with disabilities isolated, even when physically included.
-
Families may feel unheard in placement decisions or uncertain that the general classroom can meet their child’s needs, reducing collaboration.
Policy and Implementation Gaps
-
Laws and district policies may support inclusion, but local interpretations, scheduling, and staffing decisions can undermine it.
-
Schools report limited coaching, unclear guidance, and slow responses from central offices or special education support services. Link
WHAT NOT TO DO
-
Don’t act as a “host” while the para or special educator does all the teaching for the student with a disability.
-
Don’t park the student with a disability at a separate back table with an adult; this undermines peer interaction and social belonging.
-
Don’t exclude the student from group work, projects, or whole-class activities.
-
Don’t use a single teaching style (mostly lecture/text/worksheets) and assume all students will access learning that way.
-
Don’t “teach to the middle” and plan one level of materials, pacing, and tasks.
-
Don’t glance at the IEP once and then file it away; this leads to missed accommodations and noncompliance.
-
Don’t ignore or quietly drop accommodations because they feel inconvenient or “unfair” to other students.
-
Don’t let the para or specialist work independently without coordination.
-
Don’t plan in the hallway or “on the fly” instead of scheduling real co-planning time.
-
Don’t systematically water down tasks so the student never encounters productive challenge.
-
Don’t keep the student with a disability from trying grade-level work or leadership roles.
-
Don’t use supports in ways that create dependence (the adult doing the thinking, writing, or social navigating).
-
Don’t tolerate subtle exclusion, teasing, or “othering” in seating, grouping, or talk.link

PROGRAM
Universal Design for Learning – Programs and materials designed with multiple means of engagement, representation, and expression.
MTSS / RTI – Schoolwide frameworks that emphasize high-quality Tier 1 instruction, evidence-based interventions, and increased learning time (e.g., MiMTSS resources) support students with disabilities in general education rather than default pull-out.
Comprehensive SEL curricula (Second Step). SEL programs that explicitly teach self-management, social awareness, relationship skills, and responsible decision-making promote empathy, reduce bullying, and make peer inclusion more likely.
Schoolwide SEL and Leadership models (Leader in Me). Give all students roles in supporting one another, normalize help-seeking, and build a culture where diverse strengths are valued.
Peer-mediated intervention (PMI) models. Structured programs in which peers are taught how to support classmates with disabilities in academic tasks, communication, or social situations improve social networks, engagement.
Peer networks and peer support arrangements. Organized peer groups that meet around shared activities (lunch bunches, clubs, class projects) are evidence-based ways to increase interaction and reduce adult overreliance.
Cooperative learning structures embedded in curriculum. Using structured group work (jigsaws, reciprocal teaching, team-based learning) as a regular part of content programs gives natural roles for students with disabilities in mixed-ability groups.
Trauma-informed and restorative practices toolkits. Programs that build staff skills in de-escalation, repair, and student voice help keep students with behavioral or emotional disabilities connected to the community.

Inclusion (Mainstreaming)
DEFINITIONS
Mainstreaming means that a school is putting children with special needs into classrooms with their peers who have no disabilities. Often this is done during specific times of the day based on their skills. At other times, the special needs child may be studying in a resource room or “self-contained classroom.” In that environment the student has access to more one-on-one time with special education teachers and aides.
Inclusion is the newer term referring to allowing those student access to the general education curriculum and instruction without barriers.
Difference Between Mainstreaming and Inclusion: Essentially, mainstreaming requires that special needs learners adapt to the rigors of the general education classroom, whereas an inclusive classroom adapts to the needs of individual students, including those with disabilities.
