Isn't it just as, if not more, likely that a teacher would i.e. refuse to teach evolution (or even just be generally incompetent) and irremovable because of tenure? How does that improve anything?
Ah, but that is a violation of the curriculum and clear cause for removal.
Tenure isn't some magical invulnerability to being fired. It simply slows the process to a crawl and forces the collection of a mountain of evidence to fire someone for cause.
If someone intentionally, and repeatedly, violates the curriculum you can fire a tenured teacher.
You can't acquire that mountain of evidence in the 12 months between getting a ban on evolution passed and having it repealed in federal court.
Joe is right, you did contradict yourself. You originally said that tenure allows teachers to violate stupid school board decisions and to teach evolution anyway. Here, you said that tenure does not allow teachers to not teach evolution if the school board mandates it.
Which is it? Can the school board fire teachers for not following the curriculum? If so, then school boards can stop teachers from teaching evolution. If not, then teachers can choose to teach Creationism. Either way, tenure doesn't matter.
