Five weeks of online grade records and class materials affecting hundreds Palo Alto middle and high school students may have been wiped out by a computer backup that went wrong.
The grade records were from March 15 through April 26, according to Palo Alto High School's Campanile student newspaper.
School officials said Monday the loss is districtwide, affecting high and middle schools. The number of students and teachers affected is unknown, but one official said about 60 percent of teachers used the computer program -- some of whom may have kept hard copies of the records.
The Blackboard education program InClass, an online system used by many teachers to post assignments and grades, crashed April 26 after a faulty backup, The Campanile reported.
School officials told Campanile reporter Daniel Kwasnick they were working to restore the system but believed some data would be lost.
Marie Scigliano, the school district's director of educational technology, told the Campanile about 60 percent of the district's secondary teachers use InClass. Some teachers also keep paper records while others do not.
"I'm really worried for my kids," Paly social studies teacher Arlene Camm told The Campanile. "Our study guides are gone and they have finals coming up. However, I'm confident that the district will at least find a little more of the data."
Paly Science teacher Ronald Pruzan said he "lost all of my files. I was told that we had a system that worked, but apparently it doesn't."
Scigliano was not immediately available for comment. Assistant Superintendent Scott Laurence said he believed technicians are still trying to recover the data, but did not know for sure.
