Despite years of intense focus on diversity and inclusion and numerous initiatives, gender and racial disparities at senior levels persist. In 2019, the NHS reported a mean gender pay gap of over 30%. The purpose of this research was to provide NHS Trusts with actionable insights into the cultural factors contributing to inequality, pay gaps, and the under-representation of women and BAME employees at senior levels. The assessment used CultureQuest, a cultural assessment created by Psychologists at Conflux and delivered through Tivian, the leading employee feedback and reporting platform provider. The CultureQuest Parity Assessment measures both the behavioral and cultural factors that influence decisions and ways of operating. Employees across 15 NHS Trusts were invited to respond to the online survey in February 2020 and the summary of results is based upon the 5,754 completed responses.
