Koutougakou (High School) are fifteen to eighteen (public HS rarely hires non-JET ALT's, some hire only teachers with a master's degree in TESL, private schools are the best paid non-JET ALT's)
Daigakou (college) are eighteen to twenty-one (No ALT, master's required, cushiest job in all of Japan)[/quote]

What is TESL???
Also what is non-JET ALT's?? is it like a company or something??
