SUMTER, S.C. (AP) -- State agents are investigating how Sumter High School conducted a standardized test this spring.
The Item of Sumter reports that the State Law Enforcement Division agreed to investigate the school after the Education Department found problems with the test given in April that students must pass to get a diploma.
State education officials say testing materials for the High School Assessment Program were not secured and students weren't given the proper environment to take the exam.
Sumter High principal Sterling Harris wrote a letter denying some of the allegations. Harris wrote that teachers and other staff have been unhappy recently and they may have tried to take their anger out on administrators.
Violating testing procedures is a misdemeanor under state law, but teaching credentials can also be revoked.
