Los Angeles school superintendent steps down after classroom gains, but boardroom clashes

Los Angeles Unified School District officials say Superintendent John Deasy has resigned from the nation's second-largest school system.

The resignation was announced Thursday by Deasy (DAY-zee) and the school board.

Deasy was applauded for improving student performance, but he had been under fire for technology troubles.

Under Deasy, the district had higher test scores, improved attendance and better graduation rates.

But he had a rocky relationship with the school board and was criticized for his brusque leadership style.

The $1 billion plan to give each student an iPad was fraught with problems, and Deasy's communications with vendors were investigated. The district's new computerized scheduling system recently left students languishing in useless classes or without courses needed to graduate.

Deasy's contract was to expire in 2016.
