strong certified practitioners are trained to:

  • Work with clients and interpret reports.
  • Provide insight into client’s interests, preferences and personal styles.

Participants gain the skills necessary to:

  • Appropriately and ethically apply the assessment results.
  • Explain psychometric aspects of the instrument.
  • Thoroughly understand Holland’s RIASEC theory of personality and work environments.
  • Solve interpretation issues and inconsistent codes.
  • Use the instrument in diverse cultural applications.

“I have learned about the Strong Interest Inventory for a long time and had good context of it, but there is so much detail and nuance that goes along with each section that makes an interpretation so much richer. Students are coming to me to be an expert, not just someone that hands them a packet of paper and asks them how they feel about it. I feel much more confident in my career assessment abilities now.”

School Career Counselor 

“The Strong Interest Inventory is an amazing tool, and it is something I have been looking for. The Certification Program was great from start to finish and equipped me with the knowledge and skill to provide significant value to future clients.”

Corporate Coach

“I would recommend this program to others, and already have, because I believe having this certification raises my credibility in my career of human resources development and since I frequently help my peers write their resumes, cover letters, and letters of intent, I can now administer the assessment before I start that process. It is a tool that is very useful in optimizing your career coaching skills.”
