Hello @MAC2809!
At first glance, the price does seem daunting. I almost didn't apply because I felt uncomfortable with navigating how to pay for it. Honestly I was pleasantly surprised at how much Teachers College is able to help their HPSE students financially. The college offered enough assistance that I turned down full-rides from two other schools. Below are some links to websites that you may find helpful.

Also, there is an internship fair in the spring that you may attend if you are admitted!
Please let me know if you have any other questions!
