No they don't. Now if you're with the school on a field trip they have "chaperone" discounts but that's about it and you have to prove you're with a school. They also have military, membership discounts, and of you're a member at another zoo (besides one in fort hood I think) then you get 50% off
You will have to call them and ask them that, they do have discounts for field trips I believe, but to be sure you should ask them that as well
Don't know
