Visit the registration site and create a username and password. Once you input your child's information (name, grade, date of birth), you can view all the available classes, as well as those classes that have been waitlisted, which you can also add to your registration.
You can pay online by simply logging into the registration site and click the orange "Polytechnic Summer Program 2018" link on the "home" screen, under the "View My Registrations" field. This will take you to the Camp Registration page that has your registration details. Under the Financial area, click the orange button that says "new payment." This will take you to the online payment page. You may also call the PolySummer Office at 626-396-6307.
The online registration is configured to hold your registration for 40 minutes. If, after 40 minutes, you do not complete your registration, those seats in the classes are released to other families. Be sure to complete your registration within 40 minutes to get the classes you selected.
