School Committee Chair Chris Allen has announced that she will not run for reelection this year.

Allen, who is serving her second term on the committee, said she wants to give someone new a chance to serve.

"I think for any elected official, two terms is plenty," Allen said. "It's time to give somebody else a chance. You know, it's a lot of hard work.

Allen was elected to the committee in 2007 and has served during a time of budget cuts and standards-based education transitioning.

"I no longer have children in the schools," she added. "I'm very interested in North Andover's schools, have been for many years, but I've always thought that at least most of the committee should have children in the school system."

Allen would not formally endorse a candidate, but she did praise Zora Warren, a former teacher who has pulled papers for the election and attends School Committee meetings regularly.

"She's actually very impressive," Allen said.

Also running for a seat on the School Committee is Mark Mezzina, who recently passed in his signatures and has hit the ground running in the campaign.
