I will second this. I'm currently in my second year volunteering and I absolutely love it. I get to help with both the CSP (intro) and CSA (Java-based) classes. Last year I went just two days a week but this year I'm going three. Honestly, if it wouldn't be such a pay cut I would seriously consider quitting my current job and get into teaching full time. (I know money isn't everything but still).

TEALS is great because it realises that unfamiliar teachers being thrown into teaching CS probably won't turn out well for anyone. But having 'real' engineers from industry in the classroom to help teach and explain things is an invaluable resource. Plus, I've been able to get to know some of the students really well and talk to them about their college plans and beyond. I was a little nervous when I first started but it's been one of the best experiences of my life.
