COLUMBUS (AP) — Ohio education officials say school districts can have additional time to complete standardized testing due to bad winter weather.

Depending on the test format, Ohio districts have either 10 or 20 days to complete the tests — known as Partnership for Assessment of Readiness for College and Careers, or PARCC.

The Ohio Department of Education said districts that cancel school during their testing windows may add up to an additional five testing days.

Snow, frigid temperatures and wind chills reaching 25 degrees below zero this month have spurred numerous school closings across the state.

Education department spokesman John Charlton told The Columbus Dispatch that testing windows are extended each year if necessary.
