Castro Valley Unified School District will be using ParentSquare for school communication, primarily with email, text and app notifications. ParentSquare automatically generates an account for each parent, using your preferred email address and phone number. We encourage parents to access their accounts so they can download the mobile app and update their preferences on when and how they are notified.


Here’s what you can do with ParentSquare:

  • Receive messages from the school via email, text or app notification
  • Choose to receive information as it comes or all at once at 6pm daily
  • Communicate in your preferred language
  • Comment on school postings to engage in your school community
  • and so much more to come...
