Studied three common item response theory equating approaches to capturing academic growth using data from a statewide testing program: (1) linear transformation of separate calibrations; (2) fixed common item parameter calibration; and (3) concurrent calibration. Found differences in mean growth depending on ability estimate and equating procedure. (SLD)
