The program I graduated from was a PsyD professional school National Registered Program. I matched at an APA accredited internship. I am working at a Private Psychiatric Hospital and part-time independent practice.
I keep in touch with most of the graduates from my program. All are licensed. Some have thriving independent practice, Three are faculty members at University Training programs in clinical psychology. Some are working in State Hospitals. Everyone has completed their internships, postdoc, and became licensed.
All of the facts you are claiming do not seem to be happening in the real world. When I attend State Psychological Association Conferences or the APA Conference and socialize with colleagues, people are not concerned about where I graduated from or my type of degree.
All of the individuals I know who attended similar programs as my program are working as psychologist and did not have problems acquiring internships or jobs.
This may seems to be bogus to you but this is my world of experience. We actually had some students transfer from PhD APA accredited programs to our PsyD professional psychology program due to dissatisfaction with the quality of training in the PhD program and they had a specific area of interest similar to a faculty member at my school.
Related to using the EPPP and internship match rate to determine quality of a training program, extraneous variable need to be considered. People who don't pass the EPPP the first time often pass it by the third time. Some were already licensed as LPC and continue to work using their LPC license since reimbursement rate is equivalent. As one poster mentioned there is a shortage of internships and it would be a commonly held assumption that most APA accredited sites would select applicants from APA accredited programs over applicants from non APA accredited programs. Individual variable need to be evaluated as some applicants are not interested in APA accredited internships and they find a compatible site to meet their needs.
Regarding student loans, it may be common to have $200,000 or more in student loans but many of us qualify for help with paying back loans and some students are actually wealthy or family pays for their training. Usually payments are based on income variables.
Pertaining to advertisements specifying graduation from an APA accredited program, my current job was advertised in the APA Career section specifying an APA program and internship and I was selected for the position. Being from a NR program and completing an APA accredited internship is equivalent. However, before our program became NR, it did not interfere with students gaining internships and quality jobs. Some of our graduates are Clinical Training Directors at APA accredited internships and they did not complete an APA accredited internship.
We are very fortunate to have some diversity of training programs for professional psychology in either PhD or PsyD models. By having different training models, individuals may choose which models best matches their interest levels.
