The school of choice form includes a dropdown to select "Your school or program of choice selection" that is broken and it is not displaying any options in the list. This is a required field so the form can't be submitted.
I am sorry you are unable to access the dropdown in the form to select your school of choice. I suggest contacting your school district directly to inform them of the issue. Your district should be able to work with our Professional Services team to resolve this error.
