Course Description
Investigate Incidents with Greater Confidence
On completion of the qualification, learners should have the skills needed to carry out an unaided investigation of a non-complex workplace incident.
The course develops the ability to distinguish between immediate, underlying and root causes so that investigations move beyond simply identifying what happened.
Learners also develop interviewing skills and an understanding of the PEACE interview process. These competencies can also support participation in larger team-based investigations.
