description Inthis study, the equated score results of the kernel equating (KE) methodcompared with the results of traditional equating methods—equipercentile andlinear equating and 9th grade 2009 ÖBBS Form B of Social Sciences and 2009 ÖBBSForm D of Social Sciences was used under an equivalent groups (EG) design.Study sample consists of 16.249 students taking booklets B and another 16.327students taking D in that test. The analysis of the test forms was carried outin four steps. First, descriptive statistics were calculated for the data andthen it was checked whether the data obtained from the two booklets satisfy theequating conditions. In the second step, the booklets were equated according tomethods. Lastly, the errors for each equating methods were calculated. Kernelequating results were nearly same to the results from the correspondingtraditional equating methods. In Kernel equating, when parameter h was selectedas optimal, equated scores provided almost identical results as traditionalequipercentile equating. When it was selected large, this time the equatedscores provided results almost identical to traditional linear equating. It isconcluded that Kernel equating methods are relatively more the most appropriateequating method method than traditional equating methods.
