Achievement test is an assessment tool of academic outcomes of students in particular subject. The primary goal of an achievement test is to assess the mastery of knowledge in a specific subject or content. This test measures the capability of an individual in quantitative terms that shows how much individual has expertise in that particular subject. Generally achievement test is mostly used by teachers in school and colleges to assess the learning outcomes of individual in teaching learning process at the completion of the unit. This paper represents the construction and authentication of Science Achievement Test (SAT) at secondary level for 9th standard students. The researcher constructed 70 multiple choice items based on NCERT syllabus of Science taken from 3 units of biology section as mentioned “Fundamental Unit of Life: Cell”, “Tissue” and “Diversity of Living Organism”. After the item analysis 54 items were retained in the final version of tool. Test retest reliability was calculated and value of coefficient of correlation was found to be 0.78 and Cronbach α was 0.87 and validity of the test established by content validity and face validity through experts’ suggestions. This test is developed especially to knowing the learning-outcomes of students in science concepts that was taught by mind mapping techniques. The items of the test were based on the selected mind maps topics such as structural organization of cell, Nucleus, Cytoplasm etc. Mind maps are creative and logical way of representing ideas in nonlinear form and showing how you connect ideas and concepts. They allow students to create visual images to make information more meaningful and allow for deep learning to occur. Mind mapping can enhances the students’ achievement and knowledge retention because learner constructing the knowledge via understanding the concepts.
