Recruit intakes are often dictated by the requirements and the planned training courses required after basic training for each specific trades. Some trades have been rewriting course packages and missed serials, or, because the manpower requirements for that trade may be low (despite overall CF shortfalls), the qualifying courses may not be run every year, or more than once per year. To minimioze the length of time that a recruit will hang around as an untrained private between basic and occupation training, many recruits have to wait to be enrolled for the recruit course that runs just before their trade qualifying course. This is one major factor that leads to long waits for some recruits and very uneven waiting periods.
