Ms. Astin received a file for a new student. In the file the student is labeled as having autism, but Ms. Astin has spent several days with the student, and many of the serious social skill deficits one might expect from a student with autism do not seem to be evident. Whose responsibility is it to determine if the student qualifies for services under the educational classification of autism, under another category, or if the student qualifies for services under Section 504 of the Rehabilitation Act?
