The first draft of the multi-state standards declares that evolution and its underlying mechanisms are "key to understanding both the unity and the diversity of life on Earth."

Kansas is headed toward another debate over how evolution is taught in its public schools, with a State Board of Education member saying June 1 that science standards under development are “very problematic” because they describe the theory as a well-established, core scientific concept.

From 1999 to 2007, the state had five different sets of science standards for its schools as conservative Republicans gained and lost majorities on the board, which sets the guidelines. The debates attracted international attention—and some ridicule—before the latest standards, which reflect mainstream scientific views about evolution, were adopted five years ago.

Kansas is now among 26 states helping to draft new science standards alongside the National Research Council, with the goal of creating standard, nationwide guidelines. A first draft became public last month, and the Kansas board is scheduled to hear an update on June 12.

Education Commissioner Diane DeBacker said a final draft could be ready by the end of the year, and the board then would decide whether to adopt those common standards as the state’s science standards.

But the decision might not be made until after the November election—in which five of the 10 board seats will be on the ballot.

Board member Ken Willard, a Hutchinson Republican, said he’s troubled by the first draft of the proposed standards. In the past, Willard has supported standards for Kansas with material that questions evolution; guidelines that he and other conservatives approved in 2005 were supplanted by the current ones.

Willard said the draft embraces naturalism and secular humanism, which precludes God or another supreme being in considering how the universe works. He said he intends to raise the issue June 12.

“That’s going to be very problematic,” Willard told The Associated Press in an interview. “They are preferring one religious position over another.”

Kansas law requires the board to review its academic standards at least once every seven years, meaning science standards must be considered again by 2014. The state uses these standards in developing annual student-achievement tests, which, in turn, influences what’s taught in classrooms.

Board member Sally Cauble, a moderate Republican from Liberal, said she’s comfortable with the language in the draft standards. Cauble, elected in 2006 after ousting an evolution skeptic in the GOP primary, voted for the 2007 standards.

Cauble said Kansas is participating in the multi-state effort to draft common science standards because it wants to ensure that its students can compete in a global job market. She said the board should defer to scientists, science educators, and business leaders when considering changes.
