Charter schools are not allowed to discourage a pupil from enrolling or seeking to enroll in the charter school because the pupil exhibits any characteristics such as students with disabilities, academically low-achieving, English learners, neglected or delinquent, homeless, socially economically disadvantaged, foster youth, or based on nationality, race, ethnicity, or sexual orientation. Charter schools are not allowed to request a pupil's records before enrollment or encourage a child who is enrolled in a charter school to dis-enroll or transfer to another school. A parent, guardian, or pupil (18 years or older) may file a Charter School Complaint Form to the authorizing entity if they suspect the charter school is in violation of Education Code Section 47605(d)(4).
