QuickHAC is no longer supported due to changes with the district's gradebook. Do not install. You will not be able to log in. This is the reason for the recent poor reviews. If you are an AISD student, please download manaTEAMS (. Com) instead, as it is the successor to this app and adds many new features. For students of Austin ISD (AISD) and Round Rock ISD (RRISD) only!
