Where Can I get Formal Training for Coaching?

I have been coaching house league and as well helping out with high school basketball for a couple of years now. My basketball knowledge is basic but would like to increase by receiving formal instruction. I was wondering if anyone (coaches in particular) can offer any adivce, tips on where to seek formal training for basketball at the high school level. Thanks!

Go and look around other high schools and see how their coach do practicing and take notes.

there are plenty of coaching work shops i think. im not sure where because i am a player but im sure if Coach Clement or Coach Phillipe comes on they can probably help you out and point you in the right direction.
