Hi Francois,
Here are a few suggestions for you . . .
1) What concerns did PMI have about your application? Answering each concern might lead you to the best solution.
2) PM PrepCast and PMI have good articles that may help in your decision-making:
CAPM® vs PMP®: The Differences You Need To Know
Types of PMI® Certifications and Which One is Right for You?
Certification Types
CAPM certification is targeted toward anyone looking to acquire or improve project management skills. The exam is less rigorous with fewer questions, requires less experience, and is cheaper than the PMP. The CAPM certification demonstrates knowledge of PMI’s project management principles and processes, which benefits candidates applying for jobs against those without any certification. To maintain your CAPM, you must retake the exam every five years.
On the other hand, the PMP certification is the most significant, industry-recognized credential for project managers worldwide. Some employers require PMP certification when hiring project managers, as PMPs have exhibited the knowledge and skills necessary to lead complex projects and direct project teams. The PMP exam is appropriate for more established professionals with significant project management experience, and is therefore more challenging to achieve. To maintain your PMP credential, you must earn 60 Professional Development Units (PDUs) or hours of learning, teaching others, or volunteering every 3 years as a way to measure your ongoing professional development.
I think you are the best one to answer if it's worth pursuing the PMP certification. I suggest:
• Answering the concerns from PMI on your application
• Reading through the articles linked above
• If you are at a loss as to what to pursue after doing those action items, reply back to this forum thread and we will continue to guide you.
I wish you the best, Francois! Stay safe and well.
