Forty years have passed since the "Larry P. v. Riles" (1979) decision prohibiting the use of standardized intelligence quotient (IQ) tests to assess African American children in California for special education. While the "Larry P." case has governed the assessment practices of school psychologists for so many years, yet little is known about how the "Larry P." decision impacts special education due process in California. A search of the Office of Administrative Hearings Special Education Division (OAH) database of decisions issued between July 2005 and August 2018 found only 31 cases where "Larry P." was invoked, and only 5 of these raised "Larry P." as an issue, for the remaining 26 cases "Larry P." is referenced in an OAH statement or determination. Of these 5 cases, the LEA was found to be in violation of "Larry P." in 2 of the cases, both of which involved students who were incorrectly designated as some other ethnicity than African American in the district student database. For most of the cases (n = 16), "Larry P." is cited as a footnote to support decisions about the suitability of a specific test. In 3 of the 31 cases, the district proposed or conducted testing was disputed, 7 other cases involved independent evaluators, with two of the cases involving parents wanting their child to receive cognitive testing. The results indicate that districts generally prevail by following the California Department of Education's ban on administering published norm-referenced cognitive tests to African American students; however, this practice does little to challenge the institutional racism within our schools that was the heart of the "Larry P." case.
