The mistake was caught by Newton North 10th grader Michael Safran, prompting the DESE to reissue MCAS scores to schools.
In many cases student scores improved and in no instance did a student's score decrease. As reported by many news outlets last week, the mistake made by the testing contractor had the following effect on statewide students:
- 3,521 students statewide were misclassified with a performance level that was too low.
- Performance levels for 1,364 students will increase from “needs improvement” to “proficient.”
- 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.
Here is the official statement from the DESE website.
