We conducted an exploratory structural equation modelling analysis to eliminate any restrictions on the variables and to allow them to covary. While measurement invariance was found on configural and metric levels, scalar invariance was not found. The results advance the aim of the South African Personality Inventory to comply with stipulations in South Africa’s Employment Equity Act regarding fair and unbiased assessments.en© The Author(s) 2019Cross-cultural researchIndigenous psychologyMeasurement invarianceSouth African personality inventoryPostprint Article
