Waller ISD Introduces Online Gradebook. Student’s grades are now available at anytime in an online gradebook on Waller ISD’s website at https://www.wallerisd.net/pinnscripts/piv.exe?action=signin. Look for the scrolling button on the right side of your computer screen. To log in you will need your child’s student ID number and assigned password. Passwords are being sent home in letters to parents and should arrive by the end of the month. If at that time you have not received a letter, please contact your child’s campus registrar to obtain a password. Students are also able to use their password to check their grades at anytime. If you need assistance logging on, please contact your child’s campus registrar.
