Parents and students cannot register and log in to School Loop as Register Now button is missing on the login page.
If the Register Now button is missing on the login page - the school is using Standard Unified version of School Loop, which does not allow parent and student registration.

If the school site is correct, please reach out to the School Administration to check if they are going to upgrade to School Loop Plus or if they will be providing information to students and parents in a different way (not via School Loop).
