The Minneapolis School District underestimated the cost of the new teacher contract by $3.7 million due to a "significant" clerical error.
The contract will cost the district $14.7 million, not $11 million as initially estimated, Superintendent Bernadeia Johnson told school board members Tuesday.
While preparing a cost estimate for the contract, staffers from the human resources and labor relations department omitted a crucial number from the district's cost calculations.
Finance department staff members discovered the error Friday, a week after Johnson and union President Lynn Nordgren announced the original cost estimate.
No job or program cuts are imminent because the district's budget for the contract negotiations provided a cushion, district spokesman Stan Alleyne said.
"Everybody felt like they were rushing to get this done," Alleyne said. "This was a significant error, but we were prepared" for the financial impact, he added.
Despite the multimillion- dollar blunder, school board members unanimously approved the contract, which covers the 2009-10 and 2010-11 school years.
With the $800,000 fine levied last January for not meeting the state's contract deadline, the deal now has a total price tag of $15.5 million.
