Carruth was fired by the board in June. Borden's report described Carruth as a "mediocre" principal and said the board was justified in terminating him.

The district paid Borden $90,000 for the report, and Freeman said it was "well worth it."

What the Brimm Probe Found

"Illicit tampering" in the 2004 and 2005 testing.

Lax security procedures, an unexplained absence of test-tracking documents, and a failure to follow security protocols.

Roger Robinson, the district official in charge of all testing, "participated in or facilitated the tampering."

No evidence to support principal Joseph Carruth's allegations that he was pressured to cheat.

Camden was justified in not renewing Carruth's contract.

Brimm scheduler Paula Veggian deserved praise for her courage and integrity in blowing the whistle on grade-fixing.
