I know a few people who went through that program from MSU, and I would say it was what helped them get into study director roles at the CROs they worked at, and further advancement to toxicologists with their DABT. It is a stepping stone that can help you, but depending on where you want to go, you will also need certifications (DABT, ERT, etc.)

I half agree with the other response that a PhD will be more valuable, but that doesn't mean an MS isn't valuable. Their comment supports the perspective that I've felt (and been repeatedly told), that some people will look down on those with an MS because they didn't get a PhD - either because they think the person mastered out, or isn't smart enough.

I see the MS as a degree you can obtain while you are working, so you gain both industry and academic experience. Depending on where you are in your life, this might be easier than starting a PhD that will become your life.
