Matas: The last I heard, there were about 1800 BGO's in the program. They typically are assigned to schools although there were times when I assigned them to specific students, especially in the case of a candidate re-applying or one who was related to his/her normally assigned BGO. There are years when BGO's have no candidates selected for an appointment, for any number of reasons but usually due to the very competitive nature of the selection process, but also for lack of a nomination, failure to qualify medically, etc.
