The Los Angeles school district paid $200 million more in salaries than it budgeted last year even as it laid off 2,000 teachers and hundreds of other employees, according to an internal audit.
Auditors so far have unearthed no wrongdoing, but officials are puzzled, concerned and perhaps even a little embarrassed.
"We've been in the process of cleaning it up," said L.A. schools Supt. Ramon C. Cortines, who said his staff is verifying the size of the discrepancy and will, over time, determine how much relates to incomplete accounting and how much to something more serious.
The issue emerged in an audit, completed in December, on the arcane subject of "position control."
