Three incumbents on the Alexandria School Board have a solid chance for reappointment, despite challenges from seven other city residents, according to political insiders.

Judith S. Seltz, the current board chairman; Gene C. Lange, vice chairman; and Nelson E. Greene Jr. are all seeking their third three-year terms.

Mayor James P. Moran Jr., who noted that historically few incumbents have been denied reappointment, said the board favors candidates who have direct experience with the school system.

A number of past board members have come from the ranks of the local Parent-Teacher Associations, Moran said, explaining that the City Council often looks for "a representative voice -- someone who gets along with people well enough that when they speak you know they're representing the views of a substantial number of parents."

The seven-member City Council will complete the interview process for School Board candidates Saturday, and will name the three appointees at the June 26 council meeting. One of the toughest issues facing the new board is the redistricting of elementary schools.

Each year, three of the nine School Board members come up for reappointment. Board members receive an annual $4,500 stipend.

Virginia is the only state without elected school boards.

Seltz, who lives in the 400 block of Hanson Lane, has a graduate degree in education from Harvard, was an editor for publications dealing with special education law and policy, and is a specialist in early adolescent development. Seltz, 45, a two-time chairman, said she will not seek a third term at that post.
