The school system expects to enroll 650 kindergarten students in September, the highest figure in 30 years, according to Peter Rowe, the district’s deputy superintendent for finance. Enrollment records for the town go back to about 1980, he said. Superintendent Bill Lupini announced the new estimate at the March 29 School Committee meeting. The last estimate for this class was 600, which was also unusually high. “There are items we may not be able to do next year” to accommodate the larger class, he said. The district will add at least two classroom teachers and two paraprofessionals, Lupini said. - Andreae Downs
