When independence is required
An external investigator should be considered when the matter involves senior staff, raises safeguarding concerns, or where internal resource lacks the independence or capacity to conduct a thorough and impartial process. The same applies where there is a reasonable perception of bias — whether or not bias actually exists.
- Allegations involving members of the leadership team or governing body
- Grievances or misconduct matters with significant reputational exposure
- Cases where the internal investigator has prior involvement in the issue
- Matters requiring specialist scrutiny, such as safeguarding-related concerns
What external appointment demonstrates
Commissioning an external investigator signals organisational commitment to fairness. It provides a documented, impartial evidence base for decision-makers and reduces the risk that proceedings will later be challenged on grounds of procedural unfairness.
For schools, academy trusts, care providers, and charities, external investigation is often the appropriate response where governance obligations require demonstrable independence. The key is to agree terms of reference, scope, and reporting requirements before work begins.
