An urgent update must be made to PowerSchool to protect the services. All PowerSchool and PowerTeacher environments will be unavailable Tuesday, September 19th starting at 3:30 p.m. to install a release issued by PowerSchool. Once the system has been updated a message will be posted on the PowerSchool and PowerTeacher log-in screens advising that the system is back on-line and available for use. Thank you for your cooperation and patience as this urgent update is completed.
