The Texas Board of Education has unanimously rejected a Mexican-American studies textbook that experts say is rife with factual errors and anti-Hispanic bias.

Wednesday's 14-0 preliminary move must still be affirmed by a final vote Friday. But it likely dooms a textbook that has long been disputed.

Two years ago, the Republican-controlled board defeated a proposal to create a full Mexican-American studies course in Texas. Instead, it asked publishers to submit proposed ethnic studies textbooks.
