Science is critical to any society's advancement, and if it is deprived of its due role, all civilization comes to a halt. Science prepares us with a diverse set of problem-solving, logical reasoning, and creative and critical thinking abilities. In order to build analytical skills in science, one must use a variety of methodologies. Students can benefit from achievement tests in science since they assess the amount of information or competencies gained by an individual as a result of systematic science instruction. In the present study, a few chosen topics in science that are part class VIII syllabus was used to prepare an achievement test. The researcher, keeping in mind the objectives and content, prepared a preliminary draft having 78 items. After the expert, individual, and group try-outs, only 38 items were included in the final draft. The test-retest method was employed to establish the reliability of the test and the coefficient of correlation was found to be 0.87 which indicated a strong relationship. Expert judgement and content validity judgement were used to establish the validity of the test. The content validity ratio was found to be 0.99.
