We can add one more case to creationism's long record of legal failures. Yes, a creationist biology class is not adequate preparation for college coursework. The Supreme Court declined to hear an appeal in a case involving applicants to the University of California system who were deemed to have inadequate college preparation in biology. From the NCSE:
On October 12, 2010, the Supreme Court declined (PDF, p. 12) to review Association of Christian Schools International et al. v. Roman Stearns et al., thus bringing the case to a definitive end. The case, originally filed in federal court in Los Angeles on August 25, 2005, centered on the University of California system's policies and statements relevant to evaluating the qualifications of applicants for admission.<!--more--> The plaintiffs — the Association of Christian Schools International, the Calvary Chapel Christian School in Murrieta, California, and a handful of students at the school — charged that the university system violated the constitutional rights of applicants from Christian schools whose high school coursework is deemed inadequate preparation for college.
This is yet another one of those instances in which creationists try to have it both ways: creationism is religion when it's convenient accuse people of religious discrimination, and it's science when they're trying to get it into the public school curriculum.
