A testing company's mistake led to hundreds of students incorrectly receiving a failing grade on Ohio's new graduation test, including 22 seniors who still needed to pass the test to graduate, the Department of Education said Monday.

A story from the AP says, the state said Measurement Inc. graded the tests of 890 students correctly but made a mistake converting raw test data to passing and failing grades.

It was not clear whether the test was the only hurdle left for graduation for the 22 seniors given false failing grades. Schools cannot release the students' identities under federal privacy laws.

Another 45 seniors had their test results bumped up but not enough to pass the test.

The mistake was made on tests given last summer to students entering their junior and senior years as well as students who were in 12th grade last year but haven't graduated.

The state and the company planned to notify 272 school districts this week whose students were affected by the mistake.

An Education Department data analyst caught the error in October after noticing discrepancies between actual and projected results on the test.

The Durham, N.C.-based company, at the end of a five-year, $107 million contract, faces financial penalties under the agreement that would be paid to the state.

The company acknowledges the mistake and said it's the first time it made an error big enough to warrant a fine.
