Aims test score improvement under investigation

Posted: Updated:

TUCSON, Ariz. -- A big jump in tests scores, is now raising questions concerning Aims testing.

An analysis by the Arizona Republic newspaper finds at least one class in each of the 93 schools tested, saw the average scores take a one-grade jump.  Testing experts call that, "statistically improbable."

There is now an investigation.

Arizona Attorney General Tom Horne was schools chief during the years in question.

Horne doesn't believe there is improper test-giving going on.
