Yorkville does not satisfy the residency requirements for the CPO. Adler does. I called the CPO and was told that they have a great number of candidates for Psychological Associate who have graduated from Adler.
It also takes a LOT of time to become registered (4 years I believe). Since they've only been open since 2011, it's unreasonable to gauge their success as a school by how many have registered. There has not been enough time. There is one graduate who has made it to registration thus far and there are a lot of graduates who are close behind. Again, as per the CPO, the school is producing candidates.
