Score equity assessment was used to evaluate linkings of the new SAT® to the current SAT Reasoning Test™. Population invariance across gender groups was studied on the linkage of a new SAT critical reading prototype to a current SAT verbal section and on the linkage of a new SAT math prototype to a current SAT math section. The results indicated that the conversion lines obtained through subgroup-only linkings were very similar to those obtained using the total group linking for both critical reading and math prototypes. Even though there were slight degrees of divergence from the total group conversion, the differences were smaller than the differences associated with rounding rules for the SAT. Hence, on the basis of the field trial data, it appears that population invariance was achieved with respect to gender groups.
