The data analysis was based on the response of 635 students towards the test instrument of Physics Final Exam of grade XII in six schools, which were located in Bima Regency. Test instrument reliability was analysed by using Iteman 4.3 software. Standard Error Measurement analysis of the six test instruments was done by using Compound Binomial Method, Anova Method and Iteman. Index of test instrument reliability in State Senior High School 1 and State Senior High School 3 is less than 0,7, while the test instrument in State Senior High School 2 Sape, MAN, Muhammadiyah Senior High School and PGRI Senior High School are more than 0,7. Standard error measurement extremely depends on the error, which is caused by the test instrument, in this case, the reliability of some tests. The result of this study shows the teachers’ need for training in designing proper test questions. Keywords Estimation, Error Measurement, Test Instrument 1. Introduction In carrying out the evaluation, measurement is a step that must be taken. When an evaluation process will be carried out, it should be preceded by a careful measurement process. Educational measurement is an activity to quantify symptoms or objects. Symptoms or objects can be in the form of motivation, achievement, confidence or achievement, all of which are expressed in the form of numbers [1]. The numbers obtained from the measurement results will help the researcher/teacher know the level of success of the learning process carried out. Of course, the information obtained through measurement is the result of the process of analysing data with certain techniques. Then the teacher conducts an intensive assessment to see the success of the learning process, whether the numbers obtained through measurements have met the standards of success or vice versa [2, 3]. The success of the learning process can only be seen through the measurement process. To carry out measurements, a good instrument (measuring instrument) is needed, which can reflect the actual ability of the student. A good measuring instrument will provide accurate information about the success of learning. On the contrary, a measuring instrument that is not good will produce a standard error of measurement. Making good questions is one of the abilities that must be possessed by a teacher [4]. Good questions are important for teachers to get the true results of the success of the learning process. Questions / Instruments that are not good will make it difficult for teachers to get information about the success of the learning that has been done and cause a standard error of measurement. Reliability is an important requirement that must be owned by the test kits. Reliability shows the extent to which a test kit is consistent or steady in getting information when used again at different times [5]. Knowing reliability and magnitude of standard error measurement is important for an educator. This is because someone's ability can be seen from the magnitude of the standard error measurement that occurs in the testing process. The smaller the standard error measurement, the more visible the score closer to the actual score, on the contrary, the greater the standard error measurement, the score that appears to be farther away from the actual score [3, 6].
