ST. PAUL, Minn. (AP) - The Minnesota Department of Education and its student testing contractor have reached a settlement over spring testing glitches.

Pearson, the vendor, will take $1 million off its new three-year contract and add up to nearly $4.7 million in services to settle with the state.

Pearson also says it will move Minnesota Comprehensive Assessments testing next year to a new platform the company says will guard against online attacks.

The problems angered school district officials, who were frustrated by the technical woes during the testing season.

Reports say the $1 million off what was a new, three-year $40.8 million contract comes in the form of a credit to the state Education Department.

In a statement, Education Commissioner Brenda Cassellius says the disruptions this spring "were simply unacceptable."
