D.C. Mun. Regs. tit. 5, r. 5-A3050
The child with a disability shall remain in the child's current educational placement during the pendency of a due process hearing or judicial proceeding unless the parent and the LEA agree on an alternative placement.
If the matter involves an application for initial admission to public school, the child, with the consent of the parent, shall be placed in the public school program until the completion of all proceedings, unless the parent and the LEA agree otherwise.
If the impartial hearing officer decision in a due process hearing or in an administrative appeal agrees with the child's parent that a change of placement is appropriate, that placement shall be treated as an agreement between the parent and the LEA for purposes of Section 3050.1.
