Nine statistical strategies for selecting equating functions in an equivalent groups design were evaluated. The strategies of interest were likelihood ratio chi‐square tests, regression tests, Kolmogorov‐Smirnov tests, and significance tests for equated score differences. The most accurate strategies in the study were the likelihood ratio tests and the significance tests for equated score differences.
