I'm interested in teaching high school science. I thought that was the CSET I needed to take (Subtests 1 and 2 - was thinking of starting with Life Sciences and eventually getting Chem too) though it has been about 15+ years since I took any science classes. I have a month to study and pass to join a credential program. Here's my question: I also see "Foundation-Level" science. Can someone tell me the difference in what that teacher does vs the other credential? I'm looking for the best bet in getting hired, so if I'm more likely to find a job with one vs the other and add later, I can do that. Insight into the differences and demand (if you know it!) would be helpful. Thanks in advance!
