Abstract
The purpose of the study is to measure students' performance through different measurement tools and compare the findings through G Theory in order to identify the errors associated with the raters and items to improve the future applications. The sample consisted of 48 eighth graders in Kars. Two different types of exams (a multiple choice test and an essay) were applied and essays were graded by three raters. G and K analyses were performed on the results. According to the findings, the error rate was higher for the essays in comparison to multiple-choice test. The mean score was higher for the multiple-choice test, the variances were similar. There were no differences among the essay scores given by different raters.
