D.C. Mun. Regs. tit. 5, r. 5-E2109
A student shall be granted the opportunity for transfer, pursuant to this section, to high schools with special programs having specific entrance requirements, specialized curricula, and specific student performance requirements; provided, however, that a transfer under this section shall be granted only to the extent it is possible to do so without overcrowding schools, displacing other students, or disrupting the educational process.
A transfer granted pursuant to this section shall become effective at the beginning of a school year in September, and shall remain in effect during the entire period the student remains at the school; provided, however, that a student who enrolls in the public high schools of the District of Columbia after the beginning of the school year may be granted a transfer under this section at the time of his or her application.
A student who has enrolled in school pursuant to a transfer received under this section shall continue attendance at the high school of his or her choice for the remainder of the school year, unless the student applies and is eligible for a transfer under allowances set forth in §§ 2105 and 2106 of this chapter.
A student who lives within a school's attendance zone shall be given priority over a student seeking to transfer into the school.
A student who qualifies for a transfer to programs at designated high schools that are prime partners with career centers shall be given priority over other students seeking to transfer to the school pursuant to this section.
In the event the number of students to transfer into a school under this section exceeds the available space, transfers shall be determined by an impartial random selection process established by the Superintendent of Schools.
