Watertown Middle School teachers and staff have a plan in place to raise the MCAS scores at the school after a poor performance in 2018. Monday night, the School Committee heard about the strategies being used in the Watertown Schools that led to improvements for the town’s schools on the 2019 MCAS test. The Watertown Schools have made an effort to use data to drive lessons and to address weaknesses in classrooms and even for individual students, said Theresa McGuinness, the district’s Assistant Superintendent for Teaching, Learning & Assessment. “Student performance data is used to identify areas of strength and areas of opportunity, as a district, grade level, cohort and individual in English Language Arts (ELA), mathematics, and science,” McGuinness said. She added that the MCAS data is used in conjunction with other assessment tools used in the Watertown Schools.
