The key idea is that evaluating and serving students with disabilities in public schools is guided most directly by IDEA and Section 504. IDEA lays out the specific procedures for deciding eligibility, conducting evaluations, and creating an individualized education program (IEP) that provides specialized instruction and services. Section 504 prevents discrimination against students with disabilities and requires an appropriate, equally effective education through accommodations and supports, even for students who don’t qualify for an IEP. In Illinois, state regulations are designed to implement both frameworks, so districts follow IDEA’s evaluation and IEP requirements for eligible students and provide 504 plans and accommodations for those protected under Section 504. The two laws work in tandem: IDEA ensures specialized instruction and measurable services for those who qualify, while Section 504 ensures access and non-discrimination for all students with disabilities, with state rules harmonizing the federal requirements into district practice.

Stay put means the student stays in the current educational placement while disputes about services or placement are resolved. A change in placement under this rule can occur only if the parents agree to it, or if a due process decision orders a change. This safeguard keeps the student from being moved before parents or the proceeding agree on a new placement. The other options—approval by a principal, a teacher, or the school board—do not trigger a stay-put change on their own.

Least Restrictive Environment means educating students with disabilities in general education settings with non-disabled peers to the greatest extent appropriate, and providing the supports and services that make that participation possible. The idea is to give access to the general education curriculum and social interaction with typical peers, while using accommodations, assistive technology, and other supports as needed to help the student succeed. Placement should be individualized: stay in the general classroom if the student can participate and benefit with supports; move to more restrictive settings only if a less restrictive option cannot meet their needs, even with supports. The other options describe more isolating or separate environments that are considered more restrictive and used only when necessary. This aligns with the goal of inclusion and access to the full school experience.

Transition planning in an IEP is done to prepare a student for life after high school by identifying postsecondary goals and the services needed to reach them. While federal law requires that transition services be addressed no later than age 16 (and earlier if appropriate), many states implement the practice of including a transition statement by age 14 to start planning earlier. This earlier milestone ensures there is ample time to align coursework, experiences, and supports with the student’s postsecondary goals before reaching the 16-year mark. Therefore, 14 is the age reflected by this state practice. Ages like 12 are generally considered too early for formal transition planning, 16 is the federal trigger rather than the state-by-state standard, and 18 comes after high school exit, not the point at which transition planning is typically required.
