[rehab] CRC certification

[Gloria Graves]

Hello,
My name is Gloria and I'm for semester master student and am working towards a masters degree in vocational rehabilitation counseling. I am trying to get some information as to where I should start to look for study materials for the CRC exam? It's a couple years out for me but I figure it's never too early to study. Thank you for any advice you can give :-)
Sincerely,
Gloria
