To register for Parent Self-Serve on the CFBISD website, parents need their child's school ID number which can be found on their report card or lunch card. They then go to the CFBISD website, click on the Parent Information Link and Parent Self-Serve, and choose New User to create their own User ID, password, and security information. Once registered, parents can view their children's grades, attendance, health records, email teachers, and more under one account on Parent Self-Serve.
