They got rid of TATCs @ CTC months ago. They've just had a meeting on Teams to discuss with those TATCs the option to return, through what they're callign cohort 1, 2, and 3. Cohort 1 is destined to return early 2022 (We're talking Feb-Mar), Cohort 2 mid 2022 (Apr - Jun) and Cohort 3 late 2022 (Sep-Nov).
I can't imagine they'd start the recruitment process before mid 2022 - with their aim to fill cohorts for either the very end of 2022 or the start of 2023.
That's as far as we (the TATCs they got rid of) are aware.
