By now, Los Angeles Unified was supposed to be the technological model for big-city school systems.
All of its pupils would have iPads, teachers could access student data with the click of a mouse, and parents could check their children's attendance and grades daily online.

On some campuses teachers had no rosters, student schedules were scrambled and classrooms were either empty or overflowing. The computer system was so overloaded, it couldn't process simple commands.
