Courts throughout the United States have consistently supported the teaching of evolution and have rejected the teaching of creationism in the science classes of public schools. Although knowledge of these court decisions can help teachers resist pressures to spurn evolution or to teach creationism, many teachers have a poor understanding of the legal issues associated with the teaching of evolution and creationism. Incorporating these court decisions into undergraduate courses, preservice training, and in-service workshops would educate and support teachers who want to teach evolution, while helping them avoid costly and embarrassing lawsuits.
