Increasing diversity in the workforce is an important challenge. The public trust government services and companies more if they see that their social identity – race, gender, disability etc. – is reflected in the service being provided. Employers are therefore keen to improve the application rate and success rate of minority-group candidates. A recruitment campaign for a regional police service managed to increase by 50% the pass rate on a pre-employment test, amongst non-white candidates. They achieved this huge improvement by changing the wording of emailed information sent to candidates. How did this work and what are the practical implications for employers?
