Perdue announced Wednesday that he is unhappy with what he called ``woefully inadequate'' internal probes by the Atlanta and Dougherty County school systems. The investigations followed a statewide review of all standardized tests taken by first- through eighth-graders in spring 2009 showing unusual numbers of erasures on tests.
Perdue says he hopes to complete his investigation this fall. He says he plans to name a special investigator in coming days who will have subpoena power if educators in the districts refuse to cooperate.
He says criminal charges could be possible after the investigation is complete.
Atlanta schools spokesman Keith Bromery declined comment until later in the day. Doughtery County schools spokesman R.D. Harter said the district ``welcomes'' the state investigation.

Perdue says he hopes to complete his investigation this fall.
