Ron Chandler, head of technology for LAUSD, abruptly resigned.

The Los Angeles Times said that Chandler oversaw two of the disrict’s most controversial and troubled programs: the $1.3 billion iPad purchase, which was former Superintendent John Deasy’s signature initiative, and the botched MISIS computer system.

“Chandler, 52, became associated with two major troubled projects. The first was a $1.3-billion effort to provide every student, teacher and campus administrator with an iPad, a flagship initiative of former Supt. John Deasy.

“Chandler was responsible for some of the problems that accompanied the iPad rollout at 47 schools last year. For example, immediately after receiving iPads last year, students at three high schools figured out how to delete the security filter and freely browse the Internet.

“Officials immediately took back the devices and some schools made little use of them for the remainder of the year….

“But Chandler’s position apparently became untenable in the wake of a second technology project called My Integrated Student Information System, or MISIS. The system eventually is expected to integrate all student records, keeping parents informed, allowing educators to tailor instruction and helping students stay on track with graduation and college requirements. But the system wasn’t ready and caused chaos across the sprawling district of about 600,000 students.

“As if to underscore the link between Chandler’s departure and MISIS, new Supt. Ramon C. Cortines tersely announced the resignation at the beginning of an update on the records system.

“There will be a change of leadership … Mr. Ron Chandler, Chief Information Officer, has resigned,” Cortines said. “We thank him for his service.”
