Sasi is a program used by many public schools to keep track of student progress (i.e. grades, attendance, etc.) Has been found to be very unreliable in most cases. So much so that some schools have gone back to paper attendance and grades.
P.A. Announcement: Staff, please excuse this interruption. Please log out of SASI and turn off your computers, their server has gone down...AGAIN! Thank you for your cooperation.
