Purpose : To demonstrate the impact of Physical Therapy Centralized Application Service (PTCAS) five years after initial participation in the application system.Description : St. Ambrose University started participation in PTCAS during the inaugural cycle of 2008-2009. At that time, although there was an increase in number and geographic diversity of applicants, it did not lead to a more diverse or higher quality cohort of students admitted to the class. In order to examine the impact of PTCAS over time, the characteristics of the five consecutive applicant pools were compared to determine trends since initial participation in PTCAS. Additionally, comparisons were made between those interviewed and eventually admitted to each class.Summary of Use : Results: Total applications increased 76 percent over the last five years, while qualified applicants increased 24 percent. In comparison, PTCAS applications per program increased 58 percent. The most significant impact at St. Ambrose was on number of undergraduate institutions represented in those students accepting positions in the program, with a 67 percent increase. The number of applications from minority applicants doubled, as did those from male applicants. Although these increases were greater than those in the nationwide applicant pool, these increases were not reflected in the composition of the St. Ambrose class.Importance to Members: Conclusion: The results of this analysis may be useful for other programs in making a decision whether to use PTCAS for the own admissions process and the possible impact it will have on class composition. Although the applicant pools reflected more geographic and ethnic diversity, this was not reflected the final class demographics.
