The Psychological Specialty in Industrial-Organizational Psychology
Certification for I-O Psychologists. Demonstrate your competence through the profession's independent certification program.




Backed by the Profession
SIOP, Inc has promoted the PSI-O certification as an important step in advancing professional recognition and proficiency within Industrial-Organizational Psychology.


A Credential Built for Modern I-O Practice
Unlike an academic degree, the PSI-O credential verifies that a professional has met established standards for education, professional experience, and examination developed through nationally accepted credentialing practices.


"For a graduate level profession to not have a certification, that's a bit unusual... we know that there's variability in graduate programs, I-O psychology doesn't have accreditation, so there really isn't one universal standard across programs. And so that was really where it was born is that we needed an opportunity for people to demonstrate their proficiency." - Matt Turner, PhD, ICE-CCP
The Psychological Specialty in Industrial-Organizational Psychology (PSI-O) is an independent professional certification developed to recognize practitioners who demonstrate competence in the science and practice of I-O psychology.
Why Become Certified?
The PSI-O credential allows you to demonstrate your professional competence through an independent standard, distinguishing yourself from non-certified practitioners while increasing trust among employers, clients, and the public. By earning this certification, you join a community committed to excellence and ongoing learning, helping advance the recognition and professional standards of Industrial-Organizations psychology as a whole.
