What case established that IQ tests cannot be the sole basis for placing minority students in special education?

The case that established that IQ tests cannot be the sole basis for placing minority students in special education is Larry P. v. Riles. This landmark decision addressed the disproportionate representation of African American students in special education programs in California. The court found that the use of standardized IQ tests was biased and discriminatory, leading to wrongful placements of these students. The ruling emphasized that these tests alone could not accurately reflect the abilities of minority students and that multiple forms of assessment should be used to determine eligibility for special education services. This case plays a crucial role in ensuring fair educational practices and protecting the rights of minority students in educational settings.
