This study aimed at describing the creative problem solving senior high school students based on math self-efficacy (MSE) levels. To achieve these objectives the researchers use creative problem-solving stage CPS Version 6.1 namely constructing opportunities, exploring data, framing problems, generating ideas, developing solutions, and building acceptance. This research is a descriptive qualitative approach. Subjects consisted of two students with high and low MSE based on the analysis of questionnaires the PISA math self-efficacy scale. The data collection technique is task-based interviews to obtain data on students' creative problem solving. The results showed that (1) subject with high MSE doing constructing opportunities, exploring data, framing the problem, generating ideas (doing fluency, doing flexibility, without making a novelty), developing solutions, and building acceptance stage; and (2) subject with low MSE doing constructing opportunities, framing the problem, generating ideas (doing fluency, doing flexibility, without making a novelty), developing solutions, and building acceptance stage, without doing exploring data stage.
