Scholars have called for increased attention to within-group variability in models and measures of identity development. As a step toward responding to these calls, the current review focuses on the womanist identity development model as a model of gender-related identity development that has been argued to be applicable to women across racial/ethnic, class, and other groups. The review provides an introduction to the womanist identity development model and its operationalization, critically analyzes literature on the model and its measurement, and explores directions for further development of womanist identity development theory and research.
