Academic grit can be a student's rock-solid confidence to maintain focus and go on learning despite obstacles in the way of achieving their long-term goals. This investigation into points to develop an academic grit scale and determine the variables that underlie students' academic grit will help to construct a significant and reliable tool for measuring academic grit. Twelve questions that measure students' intellectual grit when thinking about chemistry make up the intended survey. 817 understudies were randomly selected from 13 different state-tall schools to participate in the test. Calculations for reliability, confirmatory factor analysis, exploratory factor analysis, and Cronbach alpha internal consistency coefficient were done in the process of constructing the scale. It has been shown that academic grit assessments are reliable and significant tools that can be used with high school students studying chemistry. The encouraging results demonstrate Three essential elements: diligence, constancy in studying, and learning focus. These findings also suggest that female students have greater perseverance in their studies than male students.
