The panel first established a clear understanding of the program’s target audience, then developed a new content outline for COAs and CPAs. In small and large groups, the panel reviewed the 2012 practice analysis content outline, identifying the key domains—the major groupings of responsibilities and tasks that constitute significant areas of the role—and the specific tasks or activities performed within each domain.
Discussions focused on ensuring the identified responsibilities and tasks accurately reflected the diverse settings in which COAs and CPAs operate. Panelists received guidance on developing and evaluating domains and task statements. As the panel refined the content outline, they evaluated the relevance and currency of each domain and task, making revisions as needed to ensure comprehensive coverage. Throughout the meetings, some tasks were reworded, removed, or reassigned to more appropriate domains.
Through an iterative process of development, review, and revision, the panel finalized a comprehensive list of four domains and 30 tasks for the COA exam, and four domains and 32 tasks for the CPA exam. The domains for each exam include:
The final domains and tasks for the COA and CPA exams are listed in Results Relating to Domains and Tasks.
The panel considered the percentage of work time that orthotic or prosthetic assistants spend on performing various practice areas as well as the frequency of time spent on devices within those areas. As displayed in Table 2, both COA and CPA panels reported spending most of their time on patient care, followed by fabrication and administration/ documentation/ other tasks related to billing, office management, inventory, or insurance.
