State expands charter investigation after IO raises questions about testing

horizonJust over a month ago, Innovation Ohio released an analysis of test scores at Horizon charter schools around the state, after reports emerged of possible test tampering at the chain’s Dayton location. In it, we showed that Horizon’s Columbus High School showed indications that state test scores were abnormally high when compared to how the school performed on independently-administered ACT exams.

Today, the Ohio Department of Education announced that it was expanding the scope of its investigation to Horizon’s Columbus school.

We’re happy¬†that the state has concluded that the questions IO raised concerning test score discrepancies at Horizon’s Columbus school bear further investigation.
