Nebraska sent the Omaha school district $6.3 million too much last year because the district mistakenly submitted a special education expense twice.

The Omaha World-Herald reports Omaha school board discussed the funding problem Monday night.

The state Education Department audited the district’s budget in August and discovered the district had submitted a special expense twice. State finance administrator Russ Inbody says this appears to be an error.

Inbody says he doesn’t know of any other school district in the state that made the same mistake.

Now that the error has been discovered, the state will deduct $6.3 million from this year’s payments to the district. This year the Omaha district has a general fund budget of about $484 million.
