Abstract: An equating design in which two groups of examinees from slightly different populations are administered different test forms that have a subset of items in common is widely used. A procedure for equipercentile equating under this design has been previously outlined, but standard errors for this rather complex procedure have not been provided. This paper provides these standard errors and a simulation that verifies the equations for large samples. A real data example is provided for considering issues involved in using these procedures.
