The evaluation of learning is a systematic process involving testing, measuring and evaluation. In the testing step, a teacher needs to choose the best instrument that can test the minds of students. Testing will produce scores or marks with many variations either in homogeneous or heterogeneous forms that will be used to categorize the scores based on the level of achievement or what the teachers desire to measure the achievements of students. The achievement measurement is measured using four types of scales normally used, i.e., the Ordinal Scale, Nominal Scale, Intermittent Scale and the Ratio Scale. The evaluation will be done based on the categories of the measurement used in which the item is used to test the effectiveness of teaching and learning in achieving its objective. The principals of authenticity, reliability, linearity, practicality, objectivity and easy-evaluation are to facilitate recording results so that the final results will not cause any questionings of reliability. There is also an example of difficulty percentage calculation and discrimination index manually done for the English Form 1 real test paper that was used in Bachok National Secondary School, Kelantan. In this example of evaluation, the analysis was made based on 40 test items on 40 students. (Contains 5 tables.)
