Career planning is an activity to help students determine future careers, such as high school, jobs and desired positions. The digital module is an alternative that can be used to convey career planning material to students. This study aims to determine the effectiveness of digital modules in improving junior high school students' career planning. This research is an experimental study using a quasi-experimental design method. The career planning instruments was tested for validation using confirmatory factor analysis, resulting in 17 valid items and a reliability of 0.830. The subjects of this study were junior high school students from the seventh-grade level. The result shows that digital modules effectively improve junior high school students' career planning, with an n-gain score of 0.60. The digital module contributes as a novelty in guidance and counselling to deliver career guidance services, besides making it easier for students to learn independently.
