The National Association of State Boards of Education will elect officers in July, and for one office, president-elect, there is only one candidate: a member of the Kansas school board who supported its efforts against the teaching of evolution.

Scientists who have been active in the nation’s evolution debate say they want to thwart his candidacy, but it is not clear that they can.

The candidate is Kenneth R. Willard, a Kansas Republican who voted with the conservative majority in 2005 when the school board changed the state’s science standards to allow inclusion of intelligent design, an ideological cousin of creationism. Voters later replaced that majority, but Mr. Willard, an insurance executive from Hutchinson, retained his seat. If he becomes president-elect of the national group, he will take office in January 2009.

The group, based in Washington, is a nonprofit organization of state school boards whose Web site (www.nasbe.org) says it “works to strengthen state leadership in educational policymaking.”
