Participants - inclusion criteria

​Eligible participants are individuals that have applied to join the Metropolitan Police Service as a detective constable and identify as an ethnic minority and/or female. They need to have passed initial employment checks (the ‘sift’). Participants must opt-in to receive the intervention.

Target Sample Size

​A total sample of 718 applicants, 359 assigned to the treatment group, and another 359 assigned to control.

Study Design

​An individually randomised two-arm randomised controlled trial (RCT).


​The intervention to be tested will be a virtual one-day workshop delivered by former police officers and assessors with specialist training. Candidates take part in a combination of individual and group exercises that aim to prepare them for their College of Policing online assessment process for new recruits.

Outcome Measures

​The primary outcome measures will be the proportion of applicants who (1) schedule, (2) attend, (3) complete and (4) successfully pass the entirety of the College of Policing’s online assessment process for new recruits. In the long-term, the proportion of candidates that subsequently graduate from detective training will also be measured.
