ACT CEO Marten Roorda issued his thoughts about the testing "mis-administration" at Bearden High School, saying he "felt the need to respond when the integrity of our organization is questioned."

In a blog post published on the testing company's website Friday morning, Roorda said ACT "deeply regrets that the students of Bearden High School have been impacted" by the situation, but places the blame for the mis-administration on the school.

"Despite procedures, instructions and protocols carefully designed to ensure the accurate ordering, delivery and administration of the test, mistakes were made by a small number of schools. One such misadministration resulted in the cancelling of scores of approximately 400 students at Bearden High School in Knox County," Roorda wrote.

He said ACT has made efforts to support and assist the affected students, and said a "great deal of incorrect information" has circulated since the mis-administration was announced.

"Integrity is a weighty word and one that my organization and I take seriously," Roorda wrote. "ACT takes seriously our duty to ensure every student—and university and scholarship agency—receives an ACT score they can trust as valid. It’s what we’ve done for almost 60 years for millions upon millions of students across the country and around the globe. Releasing scores from a test that occurred under a flawed testing administration would compromise that public trust."

ACT also sent out an open letter to Lt. Gov. Randy McNally on Thursday, after McNally, Mayor Tim Burchett and others discussed the testing issue with ACT representatives during a meeting in Nashville earlier this week.

McNally said he was "extremely disappointed" in how the meeting turned out and Burchett said the Lt. Governor was considering a push to make the SATs the future testing standard in Tennessee.
