The state is investigating K12, the nation’s largest online educator, over its alleged use of “teachers of record.”

Earlier this month, the Florida Center for Investigative Reporting and StateImpact Florida reported on the state Department of Education’s investigation of K12, the nation’s largest online educator with business in 43 Florida school districts. In a joint investigation, FCIR and StateImpact Florida disclosed how K12 allegedly used improperly certified teachers and asked employees to cover up the practice.

After publication of the story — which ran in the Miami Herald, The Ledger in Lakeland, and the Star-Banner in Ocala, among other state newspapers —  K12’s stock price dropped 13 percent in trading and public school districts in Brevard and Volusia launched internal reviews of the for-profit online educator’s records.

Follow-up reports from FCIR and StateImpact Florida revealed that K12’s student-teacher ratios are as high as 275-to-1, according to internal company records, and that few Florida school districts are able to check for problems with K12.

Responses to the FCIR-StateImpact investigation of K12 have come from around the state and across the country:
