At my unit (fairly simple aerodrome) we'd anticipate a trainee (from college) to validate in around 6 months. Obviously that time varies with standard of trainee/standard of on-unit instruction/"cross-training"/training reviews but that would be the 'normal' amount of time.
Trainees who have experience at other units (whether they've validated there or not) would generally be anticipated to validate from 3 months onwards.
Trainees who have returned to my unit from various periods at other units may validate in a month or so...depends largely on how they get on and what level of training they are assessed at shortly after returning.
Lots of variables but those are 'normal' time periods historically.
