About the Qualification
What is the International Diploma in Safety Engineering?
The International Diploma in Safety Engineering (IDSE) is a Level 6, Qualifi endorsed qualification open to everyone, from those completely new to health and safety, to experienced practitioners looking to formalise and deepen their knowledge. No prior OHS qualification is required to enrol.
What sets IDSE apart is how it teaches. Complex concepts in occupational health, safety science, and risk engineering are explained using everyday examples and plain-English analogies, the kind of explanations that make ideas click, not just stick to a page. Whether you are new to the field or a seasoned practitioner, the content is designed to build genuine understanding, not just exam-passing familiarity.
The qualification consists of two units, each assessed through a 24-hour online subjective open book examination. Three attempts are included. Learning is delivered through a structured, audio-narrated e-learning platform, so you can study at your desk, on your commute, or anywhere in between.
IDSE is equally relevant for business directors and managers who want to understand the safety systems within their organisation, those planning a career switch into OHS, and experienced practitioners ready to build a more analytical, science-grounded understanding of occupational safety performance.

Recognition & heritage
The Qualification That Set the Standard
Not every qualification is safety engineering.
The International Diploma in Safety Engineering (IDSE) is the first qualification of its kind, the one that defined what a safety engineering diploma should be. Since 2017 it has earned an enviable reputation across the Gulf countries, where it is recognised by employers and held by leading HSE corporate directors and managers in oil & gas, construction, and heavy industry.
IDSE is renowned for its innovative approach to assessment. Instead of memory-test exams, learners sit subjective, open book examinations that demand genuine understanding, and every graduate completes a personal closing interview before a certificate is issued. An IDSE is earned, never simply purchased. This is why its alumni have progressed to CertIOSH, CMIOSH, and even CFIOSH grades.
The pedigree speaks for itself. IDSE held IOSH accreditation for five years, a distinction that sets it apart in its field. That is a distinction none of its imitators has ever achieved.
IDSE is endorsed by Qualifi UK, a recognised awarding organisation in the United Kingdom. It is not an Ofqual regulated qualification. It is an endorsed qualification for professionals who want to strengthen their competence, and for those who wish to use IDSE to seek exemption from the ASP examination on the route to CSP certification.
BCSP · USA

Accept No Substitute
IDSE: The Original Safety Engineering Qualification
Before enrolling on any safety engineering diploma, consider the following:
- IDSE is a brand name Gulf employers trust. That trust has been built since 2017. A look-alike certificate on your CV does more than fail on its own. It casts doubt on every other HSE credential you hold. Once an employer questions one certificate, they question them all.
- Your interviewer may well be an IDSE graduate. 1,100+ IDSE alumni now hold CertIOSH, CMIOSH or CSP and occupy managerial and decision-making positions across oil & gas, construction, and heavy industry throughout the Gulf. They know the original, and they know the difference. Presenting a replica certificate with poor market credibility to the very people who earned the genuine qualification is a risk to your career, not a shortcut into it.
- A qualification's value is set by the market, not the certificate. Look-alike programmes may share a similar name, unit count, and format, but employers assess the qualification behind the paper. A certificate that hiring managers do not recognise, or recognise for the wrong reasons, adds nothing to your application.
- Track record cannot be launched overnight. IDSE has been delivered continuously since 2017, refined through years of assessment experience and industry feedback. Programmes created to resemble it carry none of that history, and in a field where employers hire on trust, history is the product.
Your career is built on credibility. Protect it by choosing the original.

Is IDSE a regulated qualification?
IDSE is not an Ofqual regulated qualification. It is an endorsed qualification, quality assured by Qualifi UK. Endorsed qualifications are independently reviewed against quality standards and are widely used for professional development, CPD, and career advancement, but they are not included on the Regulated Qualifications Framework (RQF).
What makes IDSE different from a standard OHS course?
Most introductory OHS qualifications focus on procedures, legal duties, and checklist compliance. IDSE takes a systems-based, scientific approach, it examines how management systems are structured and why they work, how hazards develop from a chemistry, physics, and toxicology perspective, and how technology and data can be used to prevent harm earlier. It is designed for practitioners who want analytical depth, not just procedural knowledge.
Who is IDSE designed for?
IDSE is designed for everyone with an interest in occupational health and safety, from those entering the field for the first time to experienced practitioners wanting analytical depth. This includes OHS officers and advisors, engineers, line managers, business directors, HR professionals, nurses, and career-switchers from any background. No prior OHS qualification is required to enrol.
How do I enrol or find out more?
The quickest way is to chat with us on WhatsApp or call +44 7751 137306. Our team will walk you through everything included with IDSE registration (full e-learning content for both units, access to the online exam portal, and three attempts per unit) and get you enrolled.
Is IDSE recognised internationally?
IDSE is endorsed by Qualifi UK, a United Kingdom-based awarding organisation. The qualification is available to learners worldwide and is suitable for international professionals working in occupational health and safety roles. As an endorsed qualification, its recognition will vary by employer and jurisdiction, learners are advised to check with relevant professional bodies in their own country.
Do I need any prior experience or qualifications to enrol?
No prior OHS experience or qualification is required. The IDSE e-learning content is designed to build your understanding from first principles, using plain language and everyday examples to make complex scientific and management concepts genuinely accessible. Whether you are starting from zero or strengthening existing knowledge, the course takes you where you need to go.
How does the audio-narrated e-learning work?
Every lesson in the IDSE e-learning programme includes professional audio narration alongside the on-screen content. You can follow along visually or simply listen, making it ideal for learning while commuting, travelling, driving, or carrying out everyday tasks. The narration is clear, paced for comprehension, and fully self-contained, so you do not need to be in front of a screen to make progress. Just plug in your earphones and go.
What is the closing interview and why is it required?
After completing both unit examinations, you take an online, video-recorded closing interview at a date and time you choose. The interview confirms that submitted exam work reflects your own knowledge and competence, safeguarding the authenticity and integrity of the IDSE qualification. You will be asked five questions from Unit 1 and five questions from Unit 2, followed by five multiple-choice questions (MCQs) from each unit.
Did IDSE previously hold GradIOSH accreditation from IOSH?
Yes. The International Diploma in Safety Engineering held GradIOSH accreditation from IOSH from 2017 to 2022, during which time thousands of learners undertook the qualification. Many of those graduates have since progressed to CertIOSH and CMIOSH membership, and a number have achieved CFIOSH status, a testament to the depth and practical value of the programme. That accreditation period has now concluded: IDSE does not currently support GradIOSH, CertIOSH, or any other IOSH membership grade. Its current professional recognition is TSP (Transitional Safety Practitioner) status from BCSP (USA) under the Qualified Equivalent Program.
Why is IDSE better than other qualifications that claim to be safety engineering qualifications?
Since 2017, programmes with similar names and similar-looking certificates have appeared, largely modelled on IDSE without its depth of content, assessment rigour, or integrity safeguards. Recognition is earned through years of consistent delivery, and it is IDSE that Gulf employers know and accept — with 1,100+ alumni now CertIOSH, CMIOSH or CSP in decision-making roles across the region. Before enrolling anywhere, verify the provider's track record, alumni outcomes, and assessment rigour. See the 'Accept No Substitute' section above for what to look for.
