What principle is established by the Larry P. v. Riles case?

The principle established by the Larry P. v. Riles case is rooted in the necessity of using multiple assessments for fair placement in special education. The court ruled that using a single IQ test as the sole criterion for placement in special education disproportionately affected African American students, leading to an unfair and biased process.

This ruling emphasizes the importance of a comprehensive evaluation that considers various factors, including educational, social, cultural, and psychological assessments. By advocating for multiple assessments, the case aims to ensure a more equitable and accurate reflection of a student's abilities and needs, allowing for better-informed decisions regarding special education services. The court's decision highlighted the potential harm of relying solely on standardized tests, which may not capture the full range of a student's competencies or challenges.
