IEP Modifications in Illinois: Accommodations vs. Modifications
What is the difference between accommodations and modifications in a Illinois IEP?
Modifications in the Illinois IEP alter the content, complexity, or performance expectations of the general education curriculum and carry different implications than accommodations. Under 34 CFR 300.320(a)(4), the IEP must include a statement of program modifications and supports for school personnel that will be provided for the child or on behalf of the child. Illinois regulation 23 IAC §226.230 requires documentation of the extent to which the child will not participate with nondisabled children in the general education classroom, directly linking modifications to the least restrictive environment (LRE) mandate. The ISBE IEP form 34-54 distinguishes modifications from accommodations: while accommodations reduce or eliminate the effects of a disability without reducing expectations, modifications may result in implications that could adversely affect a student throughout their education, such as reduced curriculum scope or altered grading standards. The IEP team must document the justification for any modifications and explain why the child cannot participate in the general education environment even with supplementary aids and services. Under 23 IAC §226.300, each district must ensure a continuum of alternative placement options is available, including: regular classes with supplementary aids, specialized instruction, consultation, curricular modifications, or resource services; special classes with inclusion in regular classes when appropriate; special schools; home or hospital instruction when medical conditions prevent school attendance; and state-operated or nonpublic programs for students whose disabilities are so profound or complex that public school services cannot meet their needs. A placement determination based solely on the category of a child's disability or on the current configuration of the district's service delivery system is prohibited (23 IAC §226.300). The child should not be removed from age-appropriate general education classrooms solely because of the need for modifications to the general education curriculum (ISBE guidance). Placement in the LRE must consider non-academic settings as well, including extracurricular activities and meals. For students requiring curriculum modifications, the IEP must specify the modified curriculum content, the extent of modification, how modified performance will be evaluated, and the impact on the student's progress toward grade-level standards. When modifications are used for state assessments, the IEP team must document whether the student will participate in the IAR with modifications, the DLM-AA, or be exempt from specific assessment components with justification.
