Development and standardization process of mathematics achievement test for the students of grade x

This article is concerned with the achievement test on mathematics for grade X students. The test consists of the 50 multiple choice items extracted from the grade X mathematics course. Moreover, the purpose of this study is to develop and standardize the achievement test to measure the students' cognitive level of grade X mathematics. The preliminary instrument consisted of 60 multiple-choice items and first it was tested on a sample size of 50 students of grade X. After the refinement of the test items using different procedures, 50final achievement test items were designed. The second test administration was organized after 40 days in the same group of students. This test construction and development consists of the steps as preparation of test blueprint, preliminary draft and answer key, pilot testing, item analysis, preparation of final test, reliability and validity of the test and norms. Discriminative Index and power of difficulty level was calculated. Test reliability coefficient was calculated and found to be 0.86 and also the internal consistency Cronbach’s α was found to be 0.85.Likewise, validity was also established through the expert judgment and establishing reliability coefficient. The age norm was also established.
