<![CDATA[The current research aims to validate physic learning difficulty scale for secondary school students in Indonesia. This research used a survey design. The current research participants were 388 students in Nusa Tenggara Barat, Indonesia. Two procedures were used to analyse the data: exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The results show that EFA with comprehensive techniques that compromise parallel analysis yielded a 3-factor solution: environment factor, metacognitive factor and emotional factor. The three factors solution was confirmed through CFA with the value: Chi Square=1.922, goodness of fit index (GFI)=.936, adjusted goodness of fit index (AGFI)=.913, Tucker–Lewis index (TLI)=.895, comparative fit index (CFI)=.913, root mean square error of approximation (RMSEA)=.049, and Standardized Root Mean Residual (SRMR)=.079. Therefore, based on psychometric analysis, the scale is valid and reliable to be used in measuring students physic learning difficulty of Indonesian secondary school students.]]>
