Master List Teacher Approval

There has been a lot of confusion recently about how to get approval for Master Warrior, Arch Caster, and Master Rogue teach skills. As of today, anyone with a Tier 4 skill in one of those lists may teach that list following the standard rule of three lessons.

This does NOT apply to Heroic list teach skills - for approval to teach a Heroic list, email and requests will be reviewed on a case-by-case basis.

Just to confirm- arch caster still follows the same requirement of like with like?

Until further notice, Arch Caster follows the same rules as the other master lists (anyone can teach anyone else regardless of lower professions) but we encourage roleplay that makes sense between the teacher and student. If you need help with how to explain across different sources, feel free to ask.

Can someone who teaches a master list lesson only teach one lesson per list that they possess, or is there some other limit to how many lessons they can give?

You can teach one Master List lesson per master list you have per month. (You can not teach more than one person the same list in the same month, even if you have multiple purchases of one list.) So an Arch Caster/Master Warrior could teach one student Arch Caster and another student Master Warrior, or a triple Master Rogue could teach one student Master Rogue.
