I don't know, but I remember that a slide from the NCEES from 2013 states that 30 states were already offering it, and 10 more scheduled to go online in 2014.

I don't know, but I remember that a slide from the NCEES from 2013 states that 30 states were already offering it, and 10 more scheduled to go online in 2014. So perhaps all 50 are offering it now? You'd have to call/check out the CA Board of Engineering to know for sure, unless someone here can confirm.
