You might be confusing two different things, depending on what you mean by "admissions people." The Admissions Board meets on Thursdays, reviews candidate records, and determines Board qualification based on the whole person assessment. They do not recommend or determine appointments, and candidates are not informed of their Board qualification status. Candidates who are medically qualified by DODMERB, physically qualified by passing the CFA, and Board qualified are sometimes referred to as "triple qualified". Candidates who are triple qualified and who receive a nomination are eligible to compete for an appointment.
A separate group within Admissions begins to fill the class from those eligible to compete for an appointment. That process is complex, to say the least. I am not aware that they convene on any specific date. I think that their work is ongoing until the class is filled.
