Hello.
If you meet all requirements to test for Team-Leader-In-Training and you want to test, please fill in the Team-Lead-in-Training Application at
https://apps.magicjudges.org/checklists/ (available only for L2+ judges).
Once you submit this form, the TLTP manager (temporarily me) will contact you, schedule your TLTP interview and after you pass it, the TLTP manager will also schedule the practical test.
Please, remember this is part of the L3 process. You can find information about TLTP here
