Achieving Chartered status marks the transition from a qualified practitioner to a recognized safety leader capable of influencing organizational strategy and driving excellence in workplace safety.

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
• Contributing to safety policy development or community initiatives

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.
