Professional Development and Ethics (International Diploma)

What the exam tests

Professional development and ethics tests conduct, competence and judgement. You must show how a professional maintains expertise, manages conflicts, protects confidentiality and puts public safety before commercial pressure.

Core rules

  • Ethical principles: integrity, objectivity, competence, confidentiality, accountability and respect. Do not misrepresent qualifications or data.
  • Conflicts of interest: identify, declare, manage and recuse where objectivity is compromised. Financial or personal interests must not influence risk decisions.
  • CPD: planned, recorded, reflective and relevant. It includes technical, legal, managerial and ethical learning; output and reflection matter more than hours logged.
  • Competence limits: know when to refer to a specialist (for example, occupational hygienist or ergonomist) and say so.
  • Whistleblowing: escalate internally first where safe, then to a regulator; document concerns and keep disclosures protected and proportionate.
  • Sustainability: OHS sits within ESG and human rights due diligence, including supply chains and ILO core conventions.

Worked example

A client asks a consultant to downgrade a risk rating to help win a contract. Reasoning: refuse. The request conflicts with objectivity and could mislead workers and decision-makers. Document the evidence, explain the legal and ethical consequences, and offer a legitimate risk-reduction plan. If pressure continues, escalate within the client or withdraw. Loyalty to an employer does not override public safety.

Traps

Equating legal compliance with ethics; failing to declare a conflict; claiming expertise beyond scope; treating CPD as attendance only; breaching health confidentiality; not recording ethical decisions; prioritizing commercial pressure over safety.
