SEATTLE (AP) -- Washington is one of a declining number of states that fail to analyze test results for signs of cheating.

The Seattle Times reports that while Washington has good measures in place to help prevent cheating, such as teacher training in test security, it doesn't do any of the post-test analyses that other states routinely use to detect cheating.

The state Office of the Superintendent of Public Instruction doesn't look for erasure patterns on student answer sheets that suggest someone changed wrong answers to right ones. Nor does it look for improbably high gains in a school's scores or look for other suspicious results, such as a class full of students with identical answers.

OSPI says it doesn't need to spend time and money on such post-test analyses because it's confident suspicious activity would be reported.

But national testing experts say relying on whistle-blowers and on school districts to police themselves is inadequate, especially as many states start using test scores in evaluating teachers and principals.
