What requirement was established in Larry P. v. Riles regarding intelligence tests?

The requirement established in Larry P. v. Riles specifically addressed the use of intelligence tests in the context of educational placement for students, particularly focusing on the disproportionate representation of African American students in special education programs. The ruling determined that standardized intelligence tests could not be used to classify black students into certain educational categories or programs, as it was found that these tests were biased and did not fairly assess the capabilities of all students, particularly those from different racial or socioeconomic backgrounds. This landmark case emphasized the importance of fair and equitable assessment practices, aiming to prevent the placement of students in special education based solely on flawed testing measures that did not account for cultural and linguistic differences.

This decision was significant as it aimed to protect the rights of minority students and ensure that educational assessments were valid and reliable across diverse student populations.
