I know there has been some confusion about this issue, and I was worried about it myself as I have been out 4 years and not started induction yet. I wrote to the GTCW and this is their reply. Thought it would clear up any confusion! Firstly the date you qualified would be the date that shows on your QTS certificate and not the date you received the certificate. After this extra 2 years you can still work towards completing Induction in Wales but you would not be able to carry out short term supply work.
