2,000+ Learners since 2017
~1,000 Now CertIOSH or CMIOSH members
7+ Years of proven delivery
CFIOSH Some alumni have progressed to Fellow grade
GradIOSH Accredited (2017 – 2022) For five years, IDSE held GradIOSH accreditation from IOSH — the world's largest professional body for health and safety. While that formal accreditation period has concluded, the qualification's rigorous academic content and the career outcomes achieved by its alumni speak to its standing as a serious, substantive programme. Many IDSE graduates went on to achieve CertIOSH, CMIOSH, and in some cases CFIOSH membership through their continued professional development.
About the Qualification

What is the International Diploma in Safety Engineering?

The International Diploma in Safety Engineering (IDSE) is a Level 6 equivalent, NOCN 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 60-minute online multiple choice examination. Five attempts are included in the registration fee. 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.

Why IDSE stands out

  • Systems-based approach Learn how OHSMS components interact, not just what they are.
  • Scientific and engineering depth Understand risk through chemistry, physics, and toxicology principles.
  • Technology-informed practice Explore how modern sensing, data, and AI tools support prevention.
  • Flexible online assessment MCQ exams completed remotely — 5 attempts included.
  • Audio narration — learn anywhere Listen on the commute, travelling, or during any mundane task.
  • Zero to hero — open to all No prior OHS experience needed. Plain English. Real-life examples.
  • Workplace relevant Applied content designed for real operational environments.

60-Minute MCQ Exam 5 Attempts Included
Unit 2

Principles and Application of Science and Technology in Occupational Health and Safety

This unit develops a scientific and engineering understanding of occupational hazards — how they emerge, how the body and environment respond, and how technology and data can be applied to improve prevention and control.

Key topics include:

  • Fundamentals of chemistry, physics, and toxicology as they apply to workplace hazard identification
  • How occupational diseases develop and the scientific basis for biological monitoring
  • Ergonomic principles and musculoskeletal risk — the science behind human factors in safety
  • Measurement and monitoring of workplace hazards — noise, vibration, thermal environment, and air quality
  • How technology, sensors, data analytics, and AI-enabled tools are transforming risk prevention

Common Questions

Frequently asked questions about IDSE

IDSE is a Level 6 equivalent endorsed qualification, placing it at the same academic level as an honours degree. It is endorsed by NOCN UK. It is not an Ofqual regulated qualification — it is an endorsed qualification that is highly suitable for professional development, continuing education, and career advancement in occupational health and safety.

Each of the two IDSE units is assessed through a 60-minute online multiple choice examination. Both exams are completed remotely through the ParaQual learner portal — no in-person attendance or invigilated sessions are required. The timer starts when you begin each exam and cannot be paused. Five attempts per unit are included in the registration fee.

No in-person attendance is required. All e-learning content is delivered online, and both unit examinations are completed remotely through the ParaQual portal. The qualification is fully accessible to learners anywhere in the world.

Five attempts per unit are included in the £395 registration fee. This applies to both Unit 1 and Unit 2 — giving you sufficient opportunity to succeed without additional cost.

IDSE is not an Ofqual regulated qualification. It is an endorsed qualification regulated through NOCN 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).

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.

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.

The registration fee is £395 (one-off payment). This includes: access to the full e-learning content for both units, access to the online exam portal for both units, and five attempts per unit. There are no hidden charges or additional resit fees within those five attempts.

IDSE is endorsed by NOCN 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.

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.

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.

After successfully completing both unit examinations, learners participate in a brief telephone-based closing interview conducted by ParaQual. This is not an additional exam — it is a short professional conversation designed to confirm that the submitted work is authentically your own and that you have genuinely engaged with the material. It is ParaQual's commitment to qualification integrity: IDSE holders should be recognised for real knowledge and genuine effort — not simply for having purchased a certificate. Unlike many diploma programmes that offer little more than a piece of paper, the IDSE closing interview ensures that every holder has truly earned the qualification.

Yes. The International Diploma in Safety Engineering held GradIOSH accreditation from IOSH from 2017 to 2022, during which time over 2,000 learners completed 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. The qualification continues to be delivered at the same rigorous level, now endorsed by NOCN UK.
