IOSH provides two main routes to Chartered Membership.
1) Professional Development Assessment (PDA) Route

Requirements typically include:

(e.g., NVQ Level 6 Diploma,degree in OSH) - Current role with HSE responsibilities
- Evidence of professional competence

This process usually takes 12–18 months, depending on candidate preparation.
2) Experiential Route
Designed for highly experienced senior HSE professionals who may not hold formal academic qualifications but have:
- Extensive leadership-level HSE experience
- Strategic safety management responsibility
- Proven contribution to professional practice
This route recognizes long-term industry expertise.
Continuing Professional Development (CPD) Requirement
Achieving IOSH Chartered Membership is not the end of professional growth — it is a commitment to ongoing excellence. All Chartered Members (CMIOSH) are required to maintain an IOSH Continuing Professional Development (CPD) record, which demonstrates continuous learning, skill enhancement, and sustained professional competence.
IOSH places strong emphasis on CPD to ensure that Chartered Members remain up to date with evolving safety legislation, emerging workplace risks, new technologies, and global best practices in occupational health and safety.
Why CPD Matters
Maintaining an IOSH CPD record ensures that:
- Your health and safety knowledge remains current and relevant
- Your professional competence is continually verified
- You stay informed about regulatory and industry changes
- You demonstrate commitment to lifelong professional learning
- You retain your Chartered Membership status in good standing
This process protects the credibility and integrity of the CMIOSH designation worldwide.

What Counts as CPD Activities
IOSH recognizes a wide range of professional development activities, including:
- Attending professional training courses and workshops
- Participating in industry conferences and seminars
- Completing technical or leadership development programs
- Conducting safety research or contributing to industry publications
- Mentoring junior safety professionals
- Participating in professional discussion groups or IOSH networks

These activities help Chartered Members expand knowledge, strengthen leadership ability, and enhance professional influence.
A Continuous Commitment to Excellence
Rather than being a one-time requirement, CPD is an ongoing professional responsibility. IOSH periodically reviews CPD records to ensure members remain actively engaged in professional development and continue to meet high competency standards.
CPD keeps Chartered Members at the forefront of health and safety leadership — informed, competent, and professionally relevant throughout their careers.
