Abstract	This study investigated kernel equating methods by comparing these methods to operational equatings for two tests in the SAT Subject Tests[TM] program. GENASYS (ETS, 2007) was used for all equating methods and scaled score kernel equating results were compared to Tucker, Levine observed score, chained linear, and chained equipercentile equating results. The results of the kernel chained equatings using a large fixed bandwidth were nearly identical to the results from the chained linear equatings whereas the comparisons of the kernel poststratification equatings using a large bandwidth showed differences from both Tucker and Levine observed score equating results, although for most of the score range those differences were small. Similarly, the differences were small for most of the score range in the comparisons of kernel poststratification equatings and kernel chained equatings using the optimal bandwidth with chained equipercentile equatings. (Contains 5 tables and 14 figures.) (As Provided).
