D.C. Code § 38-306: Proof of residency.

All students enrolled in District of Columbia public schools and public charter schools funded by the District of Columbia or a student for whom educational services are paid by the District of Columbia shall provide proof of residency in the District or pay tuition pursuant to § 38-302. A determination of residency status shall be made annually for each such student. The methods used to determine residency status shall be consistent across District of Columbia public schools and public charter schools and shall be crafted to facilitate rather than hinder school enrollment of eligible students.
