WORCESTER – On Wednesday, Sept. 26, the Massachusetts Dept. of Elementary and Secondary Education [DESE] notified Worcester Public Schools Superintendent Maureen Binienda that Chandler Elementary’s 2017 MCAS Scores would be invalidated due to several anomalies and severe violations.

As ThisWeekinWorcester.com reported earlier, Chandler’s 2017 MCAS scores had been under investigation since Oct. 2017.

In a letter addressed to Binienda from DESE Commissioner Jeffrey Riley, the 2017 scores were investigated due to several anomalies including: the percentage of students who were in the “Meeting Expectations” and “Exceeding Expectations” categories, averaged scaled scores, student growth percentage, timing patterns to responding to individual questions and to the test as a whole, and the number of changed responses that led to an increase in scores.

In comparison to the 2018 scores that were released on Thursday, Sept. 27, it was revealed that the number of students in the Meeting and Exceeding Expectations categories were lower in every grade and in every subject by an average of more than 20 points, the averaged scaled scores in every grade were lower than an average of nine points, growth was lower in all grades and subjects — including two grades who had extremely low median grade averages — and growth was extremely lower for those students that tested at Chandler in 2017 and then at another school in 2018.

Additionally, the state found several serious violations of test administration and test protocol.

The review of the anomalies and the violations will continue, according to the DESE.

The students who took the MCAS at Chandler Elementary in 2017 will not have student growth percentiles for that year because it requires that the test be taken subsequently year to year.
