Up to $400 million has been spent on new computers and software for classrooms, but the Los Angeles Unified School District has not tracked where all of the new technology has gone, officials said Monday.

Since 2004, the district has purchased 129,000 personal computers. But because of haphazard tracking, some classrooms still do not have enough computers for students, while others have computers but not enough software. Meanwhile, some school computers still are operating with outdated systems.

But officials have begun pushing for all district schools to have up-to-date instructional computer facilities, a plan to ensure that obsolete technology is quickly replaced, and tracking on how many personal computers are in which classrooms.

“Once we figure out what’s out there, then we can know how to fill the gaps,” said school board member Tamar Galatzan, who will introduce the resolution today. “We have software in one place and computers in another.”

I know…let’s turn over healthcare to the government because government monopolies are so efficient.

Oh, that’s harsh! But wait, there’s another $400 million LAUSD boondoggle — the high school built atop a toxic site.

And that’s not all — the very same LAUSD cannot pay its employees properly.

In the weeks leading up to the launch of a new payroll system, Los Angeles Unified School District officials had plenty of warning that the $95-million technology project would have serious problems.

Critical hardware had failed numerous times. Flawed data collected over decades proved difficult to clean up and input into the new system. Payroll clerks complained that training had fallen far short — more than 60 schools didn’t have a single staff member who’d received any training.

Still, consultants hired to implement the system urged the district to proceed as scheduled in early January 2007. Three days before the system was to begin, they urged the district in a report to “Go! Proceed . . . and go-live on January 1!”

Go live they did, plunging the district into a crisis from which it is only now emerging. Over the course of last year, taxpayers overpaid an estimated $53 million to some 36,000 teachers and others, while thousands more went underpaid or not paid at all for months.

$95 million plus $36 million to fix it. In the real world, where losing money means losing your job or your company, heads would roll.
