Hello, and welcome to the forums!
Go to Utilities > Keychain Access. In the Category box (bottom right) select Certificates, then select the appropriate certificate in the main window and delete it. You may also need to delete the appropriate password (select All Items or Passwords as the Category; the name will be the school's network and the Kind will be Airport Network Password). If the keychain is locked you will be prompted to enter your system password to delete it.
Next time you log onto the network you should be prompted to enter your password and accept the certificate.
FYI, you are encouraged to mark replies as Solved or Helpful, if appropriate, as described here.
