Notlandıranların öğrencilerin dil yeterlilik seviyesini önceden biliyor olmasının onların sözlü mülakat esnasındaki notlardırmalarına etkisi

This quasi-experimental study, focusing on scorer reliability in oral interview assessments, aims to investigate the possible existence of rater bias and the effect(s), if any, of the raters' prior knowledge of students' proficiency levels on rater scorings. With this aim, the study was carried out in two sessions as pre and post-test with 15 English as a foreign language (EFL) instructors who also perform as raters in the oral assessments at a Turkish state university where the study was conducted.
