Single-Courses to Psy.D. route?

California Southern University obviously has this option, but if you decide to go somewhere else that is also not APA-accredited, make sure that there is a requirement or option to complete internship hours within the program. Even if a state does not require APA accreditation, they may not recognize a degree program that did not include internship hours. My state requires that a certain number of internship hours be completed within the doctoral program.

CalSouthern gives you the option of internship hours as CA requires them and CalSouthern is designed to lead to CA licensure (and CA does not require APA accreditation). The OP did indicate they want to gain licensure in CA. So they should be all set there. The problem will be that they do not assist you in finding an internship and (from what I hear, not first hand experience) it's extremely difficult to find anyone willing to supervise those hours outside of APA partnerships, which are competitive in their own right.

Yes, I stated that CalSouthern has this option, but if other doctoral programs are to be considered, the OP should make sure they also have the option to complete an internship. California doesn't require a pre-doctoral supervised professional experience according to the handbook I'm reading, but not completing a pre-doctoral experience could be a limitation if the OP ever needs to leave California. This should seriously be considered since internship options could be scarce.
