February 19, 2026 ·1:20-cv-01771-JPB ·Published ·KIDD · By Aisha Johnson

The Eleventh Circuit affirmed a district court ruling that a school district complied with the Individuals with Disabilities Education Act by moving a student with Down syndrome from one special education class to another. However, the court reversed the lower court's dismissal of the case as moot regarding the student's alternative assessment placement and ordered a remand for further proceedings.

C.B., a student with Down syndrome in the Henry County School District, was initially placed in an Interrelated Resource (IRR) class for language arts and math. During his fourth-grade year, the school district's IEP team determined that C.B. was not meeting benchmarks in the IRR class and decided to move him to a Mild Intellectual Disability (MID) class for fifth grade. The MID class offered a modified curriculum and increased visual supports tailored to students with greater cognitive impairments. C.B.'s parents objected to this change, arguing that the IRR class was the least restrictive environment and that the district failed to consider mainstreaming. They requested a due process hearing, which resulted in an administrative law judge ruling in favor of the school district. The district court affirmed the administrative decision but dismissed C.B.'s separate claim regarding the Georgia Alternate Assessment (GAA) as moot, noting that the district had since determined C.B. would not be required to take the GAA. The parents appealed both the placement decision and the mootness dismissal.

The Eleventh Circuit addressed three main issues. First, regarding the least-restrictive-environment claim, the court clarified that the IDEA's mainstreaming requirement applies only to the decision of whether to educate a child in a regular classroom versus a special education setting. It does not govern the choice between two different types of special education classes, such as an IRR class versus an MID class. The court held that because both placements were special education settings, the parents could not establish a least-restrictive-environment violation based on the statutory text. Second, the court applied the standard of review for IDEA cases, emphasizing that while courts review legal questions de novo, they must defer to school authorities on educational methodology. The court found that the school district had provided a cogent and responsive explanation for moving C.B. to the MID class, citing his specific needs for an adaptive curriculum and assistive technology. Third, the court rejected the district court's mootness finding regarding the Georgia Alternate Assessment. The court reasoned that federal and state regulations require IEP teams to consider alternative assessments annually, regardless of whether the student is currently eligible for an alternative diploma. Because the assessment decision is a recurring, annual requirement, the issue remained live and legally cognizable.

The decision confirms that school districts have broad discretion to move students between different special education placements without triggering a least-restrictive-environment analysis, provided the decision is supported by evidence that the new placement is appropriate. It also establishes that claims regarding annual IEP assessment decisions cannot be dismissed as moot simply because a student has aged out of a specific testing track, ensuring that families retain the right to challenge annual assessment determinations. The case is remanded to the district court to adjudicate the alternative assessment claim on the merits.
