Answer: NCHE’s unaccompanied youth issue brief is probably your best bet. It includes the legal citations about the right to immediate enrollment, without proof of guardianship, and of course “enrollment” means “attending classes and participating fully in school activities.” It discusses the requirement for LEAs to develop, review, and revise policies to remove barriers to the identification, enrollment, and retention of homeless children and youth, including barriers due to outstanding fees, fines, or absences. Also, it specifically discusses allowing youth to enroll themselves. Lastly, because it is from NCHE, it might have more clout with a resistant district; the last page specifically mentions the U.S. Department of Education. Also, you could show the entire U.S. Department of Education’s Guidance. Question I-5 might be helpful, in addition to the tips on page 26.
