The instrument used in this research is a measurement tool with a reliability of 0.838. Statistical analysis includes confirmatory factor analysis, mean, standard deviation, and one-way analysis of variance. The study results found that scientific literacy indicators of junior secondary students had construct validity by taking into consideration Chi-square = 20.842, df = 17, p = 0.233 and X^2⁄df = 1.226. which was less than 2, while RMSEA = 0.024, RMR = 0.07, which was near to 0, GFI = 0.987, AGFI = 0.972, CFI = 0.979.
