Former D.C. schools chancellor Michelle Rhee said she welcomes a probe by the district's inspector general into standardized test scores.
Last week, USA Today reported that some high-scoring schools had high numbers of erasures from wrong to correct answers. That's raised some questions about the validity of standardized tests given during Rhee's tenure.
Rhee touted some schools for their drastic improvement in test scores.
Today on WAMU 88.5 FM, Rhee said that the school system had an outside investigator look into the erasure rates in 2009. She said education officials saw no data to indicate widespread cheating. Rhee said the new probe is needed to ease suspicion and to confirm that the scores were real.
"We should absolutely put that doubt to rest," she said Friday on MSNBC.
One possible explanation for the erasures could be that students are taught to review their answers carefully, Rhee said.
