The Courier-Journal of Louisville, Ky., reports that the state of Kentucky has concluded its investigation of Jefferson County Public Schools’ technology spending. The district had been accused of violating its own bidding policies in a deal with Apple that provided 3,000 laptop computers to students at four secondary schools. In the end, however, investigators found no violation of laws or regulations, but it did report that the district’s technology director had misinterpreted the program’s costs and understated the price tag by as much as $1 million.
