Paul Mazzuchelli, a two-term School Committee member, will not run for a third term.
Mazzuchelli said Tuesday he had struggled with the decision, but felt he couldn't guarantee a time commitment to the position, given personal and professional commitments.
Mazzuchelli is fulfilling his current term, and will have served six years when he steps down. He will continue serving on the Milford Housing Authority for at least the next year.
Two positions on the seven-member School Committee are open this spring. .
The election is April 2.
