I left in the middle of the school year last year. So did other people. Pay is very low (1700US a month). You have to pay for housing and airfare. When you arrive, you are put on probation for 3 month and administration holds it over you. You do not get health insurance until you pass the probation.

If you look at the school's page, you will see that there are 6 elementary school teachers. Only 2 of the 6 has been there since the start of the academic year. 4 people left for various reasons.

Stay away! As nice as Thailand is, CRIS is not a real school.
