How long in advance of starting data collection should I submit my proforma?
You should submit the proforma 2 weeks before the meeting at which you would like your full proposal considered. You will be given feedback within a week of the meeting and any revisions will take a week to be reviewed. Therefore you should submit projects at least 4-6 weeks before data collection (This assumes that you provide revisions in a timely fashion.) If your proposal is a fast-track proposal then it will take 7-10 days to review.
