According to the official MSPP website what is optional is whether the student does an APA-approved internship or a non-APA one (they offer a 2 year, half-time internship through their own school). In either case the internship consists of 2,000 hours of clinical practice. Check out their website info below.
Pratica & Internship
Field Placement & Training | Pratica & Internship | Sample List Of Placements
The First Two Years: Practica
Practica have training goals consistent with the curricular goals of Year I and II. At this stage, field placements emphasize broad exposure to varied populations and life span issues, theoretical orientations, assessment procedures, and modalities of intervention. Practica require 16 hours per week in the first year and 20 hours in the second year. Field placements are approved for one year of training.
Incoming students may request that their current work site be evaluated as a practicum site. In order for this to happen, the site must comply with the School's standards as well as meet the learning needs of the student. Such requests should be made on the admissions application and then discussed at the admissions interviews. Decisions regarding these requests are made after admission but prior to registration. Approval for such sites is for one year only.
Internship Readiness Committee (IRC)
As students near the end of the second year, they are assessed by the Internship Readiness Committee (IRC) for their readiness to proceed to the internship level of training. This is based on the acquisition of particular knowledge, skills, and attitudes. The IRC considers the student?s academic, clinical, professional, and interpersonal development through a comprehensive review of the student?s academic record. After successful completion of relevant coursework and practica, and certification of readiness for internship, a student can begin his/her internship.
The Second Two Years: Internship
Internship training spans the third and fourth years of the program in two half-time placements. These occur while students complete the academic requirements of the program. Students may remain at the same site both years or may be at two different sites. Whichever option is chosen, MSPP faculty work with students and field sites to ensure that this advanced training is singular in nature, with a common understanding of the School?s and student?s overall educational plan and learning objectives.
The internship totals 2000 hours and must be completed within a 24-month period. Students typically spend 25 hours per week at their training sites when choosing a two-year, half-time internship plan. Students may elect to train in a full-time internship program. Students considering this option locally must generally complete their elective courses in the third year to allow for the demands of a full-time internship in year IV. Students interested in a geographically distant internship must add a fifth year to the program to complete the requirements.
