LITTLE ROCK, AR - A mistake made by a school testing company means Arkansas school officials spent hours analyzing inaccurate data and will have to redo their work.
Jodi Goldman, a spokeswoman for Riverside Publishing, says scorers failed to include results of a math computation section when figuring each school's overall math scores.
She said Riverside will issue corrected reports by early next week at its own expense. She attributed the mistake to a miscommunication.
The mistake affected the results of the Iowa Test of Basic Skills and the Iowa Test of Educational Development. Schools use the test to see how students compare with others around the country. The state Education Department says the error affected the scores of 238,000 students in grades three through nine.
