Understanding the grade

What does CertIOSH mean?

CertIOSH means Certified Member of IOSH.Once IOSH awards this grade, you can use the post-nominal while you hold Certified membership.

It is particularly relevant to experienced health and safety advisers, managers, consultants and professionals with higher-level responsibility. It represents a more advanced stage of development than Technical membership.

Qualification ≠ membership.SHEC Learning® supports your learning and career planning. It does not award CertIOSH or guarantee IOSH approval.

Professional experience

What experience should I be able to explain?

Describe the work you actually do, the decisions you make and the people or systems you influence. A job title alone does not demonstrate the relevance of your experience.

Experienced advisers

Explain your autonomy, professional recommendations, range of risks and contribution to organisational arrangements.

Managers and HSEQ professionals

Show your responsibilities for policy, monitoring, competence, incident learning and performance improvement.

Consultants

Explain the scope of your client work, advice, decisions and improvements. Consultancy status alone does not establish eligibility.

Keep your CV and role descriptions clear, accurate and current. IOSH may request further information to understand your professional background.

Your starting membership grade

Do I need TechIOSH before CertIOSH?

You do not necessarily need to spend time at every membership grade in order. If your existing qualifications and experience meet a higher grade’s requirements, IOSH can advise on the appropriate application or upgrade.

Progressing from TechIOSH

As your responsibilities broaden, review higher-level qualifications, experience and CPD against Certified membership criteria.

Read the TechIOSH Membership Guide →

Progressing from Affiliate

Affiliate membership does not prevent you requesting an upgrade when you meet the relevant criteria. The decision remains with IOSH.

Application and upgrade

How do I apply for CertIOSH?

1. Check your qualification

Confirm IOSH’s current recognition of your qualification and clarify anything uncertain with its membership team.

2. Review your experience

Prepare an up-to-date CV describing relevant responsibilities, professional decisions and achievements.

3. Bring your CPD up to date

Record development and reflect on learning and its application to your work.

4. Prepare supporting information

5. Apply directly to IOSH

Use IOSH’s current membership or upgrade process and pay the applicable fees.

6. Maintain your membership

Continue meeting CPD, renewal and professional obligations after your grade is confirmed.

View IOSH’s current Certified membership guidance →

Continuing professional development

How much CPD does CertIOSH require?

IOSH’s dedicated CPD guidance requires Certified Members to complete and record 30 hours every 12 months, under its joining and renewal arrangements. CPD is required for Certified membership, not only when preparing for Chartered assessment.

Use learning that develops your competence: professional reading, courses, webinars, mentoring, projects and reflective workplace learning. Record what you learned and how it affects your practice.

IOSH can audit CPD. Its guidance warns that failing to meet obligations can result in transfer to Affiliate membership. Check its arrangements if you recently changed grade or need support.

Value for your career

What can Certified membership offer?

Professional recognition

Use the CertIOSH post-nominal while you hold the grade and demonstrate your continuing professional development.

Resources and professional connections

Access IOSH membership resources, communities and development opportunities that support your practice.

A route towards Chartered status

Prepare for IOSH’s professional assessment when your competence, evidence and career objectives support that step.

Membership does not guarantee a particular role, promotion or salary. Employers also consider sector experience, communication, judgement and demonstrated competence.

From CertIOSH to CMIOSH

How does the Professional Development Assessment work?

The PDA is IOSH’s assessment route for eligible Certified Members seeking Chartered status. It is separate from completing a Level 6 or Level 7 qualification.

1. Knowledge assessment

A Chartered-level multiple-choice assessment checks knowledge against IOSH’s competency framework.

2. Portfolio and discussion paper

Use recent work to demonstrate competence and write a reflective professional discussion paper.

3. Professional discussion interview

Discuss your evidence and professional practice in an online interview. IOSH also reviews CPD and ethical-practice requirements.

You need active, paid Certified membership and must meet IOSH’s eligibility rules. Its current process allows 18 months from registrationto complete; this is not a guaranteed completion time.

Chartered status also requires the IOSH Ethical Practice assessment and maintained CPD.

Qualification and Chartered status

Do I need Level 7 to become CMIOSH?

Level 7 is not automatically required for Chartered progression. IOSH controls its membership and professional assessment requirements.

A Level 7 Diploma can support strategic development where that is your objective, but it does not automatically award CMIOSH. Choose qualifications for the competence you need to develop, alongside a separate review of your IOSH pathway.

Compare Level 6 and Level 7 →

A possible professional pathway

Build qualification, responsibility and membership together

1. Level 3 and experience

Establish operational knowledge or competence and relevant practical experience.

2. TechIOSH

Apply when IOSH’s Technical membership criteria are met.

3. Broader professional responsibility

Develop autonomy, organisational systems and more complex professional judgement.

4. Level 6 or appropriate higher development

Choose a qualification that meets your current role and development needs.

5. CertIOSH

Apply when the relevant qualification, experience and CPD requirements are met.

6. PDA and Chartered progression

Demonstrate competence through IOSH’s assessment when ready; CMIOSH follows successful approval.

This illustrates one pathway. Existing experience and qualifications may support a different starting point; every grade need not be completed in order.

Frequently asked questions

Understanding Certified membership

What is CertIOSH?

CertIOSH is the post-nominal used by Certified Members of IOSH. It recognises an advanced stage of professional development.

What qualification do I need for CertIOSH?

The standard qualification route requires an appropriate IOSH-accepted Level 6 or Level 7 occupational safety and health qualification, alongside relevant experience and CPD.

How much experience do I need?

IOSH currently requires at least two years of professional experience for the standard qualification route. It assesses the relevance of your background.

Does Level 6 automatically award CertIOSH?

No. An appropriate qualification can satisfy the educational component, but IOSH separately decides whether you meet its membership requirements.

Can the ProQual Level 6 NVQ support CertIOSH?

The ProQual Level 6 NVQ Diploma in Occupational Health and Safety Practice can support the qualification element of a Certified membership pathway. Check IOSH’s current recognition and your full eligibility before applying.

Can Level 7 support CertIOSH?

An appropriate accepted Level 7 qualification can support the qualification route. The ProQual Level 7 Diploma in Strategic Health & Safety Leadership and Management is a strategic diploma, not an NVQ or a master’s degree.

Do I need TechIOSH before CertIOSH?

You do not necessarily have to hold every grade in sequence. IOSH determines the appropriate grade from your qualifications, professional experience and other requirements.

Can I progress from Affiliate to CertIOSH?

Potentially. Affiliate members can request an upgrade when they meet the relevant criteria. IOSH reviews and approves the application.

Does CertIOSH require CPD?

Yes. IOSH’s dedicated CPD guidance requires Certified Members to complete and record 30 hours of CPD every 12 months, subject to its membership-cycle arrangements.

How much does CertIOSH cost?

IOSH currently lists the annual Certified membership fee at £183. VAT may apply; confirm the current amount and terms directly with IOSH. This is separate from course or assessment fees.

What comes after CertIOSH?

Certified Members may work towards Chartered membership through IOSH’s Professional Development Assessment when ready and eligible.

How do I progress from CertIOSH to CMIOSH?

The PDA involves a knowledge assessment, evidence portfolio and professional discussion paper, followed by an online interview. CPD and ethical-practice requirements also apply.

Do I need Level 7 for CMIOSH?

Level 7 is not automatically required. Chartered progression is determined by IOSH’s professional assessment and eligibility requirements, not simply completion of another qualification.

How long does the PDA take?

IOSH allows 18 months from PDA registration to complete the process. This is a completion window, not a guaranteed timescale.

Can I become CertIOSH without a Level 6 qualification?

IOSH offers an experiential route for established OSH leaders without the usual accredited Level 6 or Level 7 qualification. Eligibility and successful professional assessment are required.

What is the IOSH experiential route?

It assesses substantial relevant leadership experience through a knowledge assessment and evidence-based professional assessment. IOSH’s guidance refers to five to ten years of relevant OSH leadership experience. It is not an easier or guaranteed route.
