No, we don't get paid extra for those trainings/workshops/etc. I'm a teacher and a coach. Been doing it for 22 years. I love it. However, there is a HUGE misunderstanding of all the "free time" teachers, and especially coaches, get during the year. I've been an AD as well and I can tell you that there's no comparison as to the amount of hours and responsibilities between an AD and a teacher. The AD is, and should be, paid like an administrator.
So I'm all for raising the pay for teachers and more specifically, teachers who coach. And saying that teachers only work 9 months a year is absurd, false, and misinformed.
