Paraoptometric Certification Exams

The AOA offers four levels of Paraoptometric certification, Certified Paraoptometric (CPO), Certified Paraoptometric Assistant (CPOA) and Certified Paraoptometric Technician (CPOT) and Certified Paraoptometric Coder (CPOC).


The purpose of the CPO, CPOA, CPOT and CPOC examinations is to assure a level of knowledge to perform the functions necessary to each certified designation. Each program requires successful completion of an examination prepared and administered by the Commission on Paraoptometric Certification (CPC) with the assistance of Professional Testing Corporation (PTCNY). Recipients must renew their certification every three years to remain current in their field. AOA membership is not required to become certified or to maintain a paraoptometric certification. 

Paraoptometric certification is a program developed by a respected panel of American Optometric Association (AOA) certified paraoptometrics and doctors of optometry, created to encourage continuing education and knowledge as the field of optometric assisting grows.  

The CPO TM, CPOA TM and CPOT TM examinations are accredited by the National Commission for Certifying Agencies (NCCA). The NCCA accreditation serves as a benchmark on how organizations should conduct certification and clearly distinguishes the excellence and value of CPC certification. The CPC is a member of the Institute for Credentialing Excellence, an organization that provides education, networking and other resources for professionals.
