MCAS Testing Error

BOSTON, Mass (AP)-

Massachusetts education officials say more than 3,000 students who passed the spring 2011 Grade 10 MCAS math test achieved a higher performance level than first indicated.
School districts were informed Friday that although the tests were accurately scored, an error made by the testing contractor resulted in inaccurately scaled scores for the 70,000 students who took the test. As a result, 3,521 students statewide were misclassified with a performance level that was too low.
Now, performance levels for 1,364 students will increase from “needs improvement” to “proficient.” The performance levels of 1,887 students will increase from “proficient” to “advanced.”
Statewide, the corrected performance level means that 77 percent of 10th graders scored “proficient” or higher in math, up 2
percent from the previously reported figure of 75 percent.
