Section 504 mandates that public schools must evaluate alcoholic or chemically dependent students and provide appropriate educational services if the need is indicated. These services can include special education, even though chemical dependency is not a handicapping condition under EHA, and EHA funds cannot be used to provide these services. Thirty-six States, three territories, the District of Columbia, and the Bureau of Indian Affairs responded to a survey designed to determine whether these jurisdictions classify ACD students as handicapped and eligible for special education services. There were no States whose special education regulations include chemical dependency as a distinct classification. Most of the States provide schoolwide drug prevention programs through regular education. More intense services for ACD students are usually not provided. 1 table, 21 references.
