A special election may be needed to decide the fate of one of the three open seats for Charlestown on the Chariho Regional School Committee.

Holly M. Eaves and Joseph M. Ungaro Sr. each received four write-in votes. They have not said if they will accept the position.

If both express interest, a special election would have to be held to break the tie.

Incumbent Andrew J. Polouski, a Republican, was the top vote getter in the School Committee race with 2,506 votes.

Polouski, a former Charlestown councilman, who was first elected to the School Committee in 1994, was the only candidate who declared for one of the three open seats.

The other open seat went to Andrew J. McQuaide, an independent. McQuaide, 18, a freshman at the University of Rhode Island, who graduated from Chariho High School last year, received 166 votes.

McQuaide said he decided to launch a write-in campaign after learning there was only one candidate in the running and was concerned about the makeup of the committee.

“I think that one thing the committee needs is a student perspective,” McQuaide said.

Bernard J. Bishop, who received five write-in votes, declined the seat after consulting with his family.

Bishop is the wastewater superintendent in South Kingstown, a member of the Charlestown Parks and Recreation Commission and president of the Narragansett Water Pollution Control Association.

The election results are yet to be certified by the state Board of Elections.

In Hopkinton, two of the three open seats were also decided by write-in votes.

Republican George M. Abbott, the only candidate who declared candidacy, garnered the most votes with 2,143 votes.

The other two seats went to Robert A. Petit, who received 102 votes, and William J. Felkner, who got 98.

Both have accepted the seats.

Felkner, a Republican, said he had been thinking of running for the School Committee next year, when his oldest daughter starts school, but decided to launch a write-in campaign this year after several people approached him because there was only one name on the ballot.

“This just seemed a logical progression as the kids were getting older,” Felkner said.

Felkner said he and the other two Hopkinton representatives-elect, Abbott and Petit, have discussed creating a Web site to get more feedback from parents.

Referring to two studies conducted by The Education Partnership, a business-backed policy group, Felkner said he favors facilitating the removal process for ineffective teachers, and assigning teachers based on subject expertise – rather than seniority. He also favors linking pay to teacher performance.

Richmond’s open seat went to Terri L. Serra, a Democrat, who earned 2,506 votes.

Serra has two daughters in the Chariho Regional School District and has been active with the American Red Cross and the Chariho Cowboys cheerleading team.

The new School Committee will be in charge of a building plan that will go before voters on Nov. 30. Four building plans have been rejected since 2000.
