D.C. Mun. Regs. tit. 6, r. 6-C3804
In accordance with section 953 of the CMPA (D.C. Official Code § 1-609.53) , all appointments to the Management Supervisory Service, except as specifically limited in this chapter, shall be by open competition on the basis of merit by selection from the highest qualified applicants, based on specific job requirements with appropriate regard for affirmative action goals as provided by law and as determined under this chapter.
An appointment to the Management Supervisory Service may be made for an indefinite period, or as a time-limited appointment.
Because an appointment to the Management Supervisory Service is an at-will appointment, a date specifying the duration of a time-limited appointment shall not prevent the termination of the employee occupying such a position prior to the date specified; provided that the termination is effected pursuant to section 3813 of this chapter.
