Tonight is the final public forum on a later start time for Northampton High School. Superintendent Brian Salzer will meet with the pubic on the matter for the fifth time, tonight from 7:00 to 8:30 at the school library. Salzer will review three proposals for a later start time that have been discussed at previous forums. Members of the community are also invited to weigh in. He'll make his recommendation to the School Committee in September.
