In recent guidelines for fair educational testing it is advised to check the validity of individual test scores through the use of person‐fit statistics. For practitioners it is unclear on the basis of the existing literature which statistic to use. An overview of relatively simple existing nonparametric approaches to identify atypical response patterns is provided. A simulation study was conducted to compare the different approaches and on the basis of the literature review and the simulation study guidelines for the use of person‐fit approaches are given.
