Abstract

The purpose of this study was to determine to what extent teacher-made tests are effective and to identify the factors that inhibit high school teachers of Addis Ababa from analyzing and evaluating their exams a fter they have administered them. To check the quality of the test, two tests of final exams from five sample schools were taken. This helped to check the quality of the test items from the response of the test takers by computing difficulty and discrimination indices. To see the internal consistency of the tests, KuderRichardson KR-20, and Spearman Brown, s plit -h a lf methods were employed. Moreover, qualitative description of the test was made by observing the test papers based on the principles of test construction . In addition, the correlation of average teacher-made tests of students' score and the national exam score of the students were computed. By using qucstionnaire relevant data from teachers, and by conducting interview with principals about the overall condition of the schools data, that can limit teachers from making posttest analysis, were secured. The finding demonstrated that test qualities currently are not as such good in terms of their difficulty level, discrimination power and internal consistency. The qualitative data a nalyses have also indicated that most of the tests are not constructed as per the principle of test construction q Teachers are also found not in a position to make posttest analysis. To minimize the problems associated test or test items evaluation the need to encourage teachers to en gage in such practice is highly recommended.
