A survey design with six years of mathematics model exam, syllabi, and textbooks served as the key data sources was considered in the study. Kendall’s coefficient of concordance and chi-square test of statistical treatment were used to analyze the quantitative data obtained. In addition, the qualitative data were evaluated using narration and description. e study’s statistical findings revealed that there was no relationship between test items and learning outcomes in cognitive domain categories or main textbook content. As a result, the exam items did not correspond to the syllabus’s objectives and content. Furthermore, the qualitative data revealed that the test items were unclear, poorly laid out, and multidimensional, as well as having low content validity. 1. Introduction A test or examination is an educational assessment to assess student’s learning. Examinations are not meant to trick students or confuse them. Examinations should be related to important learning outcomes, objectives, goals, and/or course competencies. Scholars in the field of measurement evaluation consider examinations for three reasons [1]. First, examinations help to evaluate students and determine if they are learning what a teacher expect. Second, well-designed tests inspire and structure students’ academic endeavors. Students study according to how they expect to be tested. It is easy to memorize facts, but it is difficult to comprehend and apply information. ird, tests can assess teacher’s presentation skills. In addition to reinforcing learning, tests can help students identify areas of weakness and focus their study efforts [2]. According to Coombe, Folse, and Hubley [5], exami- nations are systematic procedures administered to get in- formation about students’ performance. e results of examinations not only reflect students’ level of success, but they also give information to stakeholders about the other components of teaching process. e information provided can be used to make decisions in a variety of educational situations [4]. Brown [3] stated that a well-designed ex- amination or test is a tool that provides an accurate measure of the test-taker’s ability within a particular domain. Ac- cordingly, for tests to help stakeholders make relevant de- cisions, they must possess two important characteristics, namely, validity and reliability. Teachers should pay atten- tion to and check whether measurement tools function for the purposes that they are intended to serve or not. is means that when tests do not attain the quality of truth- fulness, teachers are not advised to use tools for decision- making. Hence, in preparation of tests, teachers need to look into and take practical measures to enhance the validity and reliability of their classroom tests [6]. Tests in mathematics are supposed to be valid and re- liable measures of ability. e extent to which teachers are able to construct and apply valid assessment instruments is determined by their understanding of validity as a means of ensuring classroom assessment quality.
