The application of the case method stage indicators forms the basis of student literacy habits. Experience following the stages of the case method directs students to gradually explore the case-solving activities given. Improving student solving skills through literacy optimization shows an important influence of the case method applied as a flow of learning activities. Applied the stages of the case method, it will be analyzed which stages are more dominant in influencing case-solving skills through literacy activities. Tests were carried out with descriptive analysis and linear regression analysis. The valuation instrument is prepared by adapting the valuation process. There are 4 stages in the case method, namely: Problem/Dilemma Selection; Presentation Issues; Preparation Issues; and Curricular Issues. The four stages have specific specifications for improving literacy skills. The literacy used in presenting solutions to given cases is more likely to be applied in 2 stages (Preparation Issues-and Curricular Issues). At this stage, the increase in literacy reaches 60% with an average per work indicator. The percentage of this achievement is obtained based on the treatment given in solving cases through structured training through various systematic procedures and strict supervision of learning activities. Adjustments need to be made in monitoring activities for the settlement of proposed cases to achieve acceptable solutions. The solutions provided need to be tested and go through an evaluation process from various literacies that are analyzed in concluding. By following the stages of this process, students become trained and experience an increase in problem-solving literacy, although they have not yet become accustomed to providing solutions individually.
