Mount Greylock School Committee Hears 'Remarkable' MCAS Data
WILLIAMSTOWN, Mass. — The Mount Greylock Regional School Committee on Thursday heard that students across the district showed significant growth in their performance on the commonwealth's spring 2026 round of standardized testing.
Superintendent Joe Bergeron and committee member Curtis Elfenbein offered the panel its first look at the results of the most recent Massachusetts Comprehensive Assessment System tests.
"One thing I do want to say is that many people can look at scores and see them in a vacuum and think the score is the thing," Elfenbein said. "But in an academic setting, there's performance and then there's growth. And over the last decade or so of my teaching career, there was a massive shift toward an increase in focus on growth."
Elfenbein explained that the "student growth percentile" in MCAS reporting measures how an individual student performs in a given year relative to students who got the same score on a given test (mathematics or English language arts) in the prior year.
"So Timmy and Joanny each get 75 percent of the questions right on the fifth grade ELA MCAS," Elfenbein said. "Then they take the sixth grade ELA MCAS, and whoever improves on their score more gets a higher student growth percentile."
An SGP of 50 percent means that a student showed typical growth relative to his or her peers.
And in that measure of growth, Elfenbein said the district's results are "remarkable."
Williamstown Elementary School showed gains in SGP in fourth, fifth and sixth grades with all three groups measuring above 50 percent, Elfenbein said.
Down the road at the district's other elementary school, the student growth percentile numbers were even more impressive.
"The SGP on the ELA MCAS at Lanesborough Elementary School in the sixth grade was 75.8 percent, which is a truly remarkable number, something I would reach for every year as a teacher," Elfenbein said. "At Lanesborough Elementary, also in sixth grade … the highest SGP is sixth grade math: 83.5 percent in 2026. I can't even put into words how massive that growth is in the scores."
Elfenbein said he gets choked up talking about the district's progress among students with disabilities, one of the subgroups in the MCAS numbers. He reported the district showed more than 50 percent SGP scores for all students with disabilities.
Districtwide, he said the Mount Greylock district's 2026 MCAS results show, "a strong reversal in the perceived decline in math testing scores and in ELA as well.
"I don't want people to see scores in a vacuum and think, 'Oh, that's a terrible score,' " Elfenbein said. "The growth is really the true measure of a student's mastery, fluency and understanding of content area. And we're seeing truly remarkable gains."
Bergeron noted that Williamstown Elementary has been named a "School of Recognition" by the Department of Elementary and Secondary Education. That makes two years in a row that one of the district's elementary schools has earned recognition for academic growth.
"[The School of Recognition honor] is quietly released as the state does its initial round of data release, but as we move toward January, there's a public celebration at the Statehouse," Bergeron said. "And we will gear up and prepare our community for that."
Both Bergeron and Elfenbein pointed to the hard work of teachers and students and the use of a new mathematics curriculum across the district as playing roles in the strong growth in standardized test scores.
"The big picture is that with our math curriculum implementation, we're a year or two ahead of where we thought we would be," Bergeron said. "Our students have done an incredible job. Our staff have done an incredible job of taking on something new that we believe — and we think we are already seeing — is advantageous.
"But it takes transition. And it takes effort to adopt and figure out and find your stride with. Our numbers, when you look across both our population as a whole and, particularly, our high needs population, have risen."
Elfenbein emphasized that MCAS data is just one data point to be looked at by the School Committee's Outcomes Subcommittee, but the standardized test scores happened to be released in early fall in time for the full committee's October session.
And he said the Outcomes Subcommittee and school administration will continue to look at the reasons why the MCAS gains were achieved.
"Whether that's new curriculum being implemented, changes in ways the classroom is operating, additional supports, we'll beat the bushes to see what the driver is," Elfenbein said. "But I do have to say the new curriculum is a huge driver of that. And I'm really impressed with the work our teachers are doing with that curriculum."
