Atlanta (AP) - An investigation by The Atlanta Journal-Constitution shows that hundreds of school systems nationwide exhibit suspicious test scores pointing to the possibility of cheating.
The newspaper examined results on standardized achievement tests for 70,000 public schools. It uncovered high concentrations of suspect scores in school systems from coast to coast.
The analysis doesn't prove cheating. It reveals that scores in hundreds of cities followed a pattern that, in Atlanta, indicated cheating in multiple schools.
The newspaper used statistics to identify unusual score jumps and drops on state-mandated math and reading tests.
The AJC reported in 2008 about statistically improbable jumps in test scores within the Atlanta Public Schools system. A subsequent investigation by Georgia officials found that at least 180 principals, teachers and other staff took part in test-tampering.
