Work readiness is essential in preparing students to enter the actual workplace. The lack of work readiness will make it difficult for students to survive in the contemporary workplace and lead to unemployment. Internship and self-efficacy are the keys that will lead the student to succeed in the workplace. This research examines the influence of internship and self-efficacy on student work readiness. The data were collected from 200 higher education students in Jakarta using a questionnaire. Only a few studies have been done on this subject, with Multiple Regression Analysis to explain the research phenomenon and validate the research hypothesis. Rasch Model was used to clean biased data, convert ordinal data from Likert Scale questionnaires to interval data, and examine the validity and reliability of the questionnaire. The findings show that the internship and self-efficacy directly impact work readiness simultaneously. Thus, in addition to academic achievement, the students should have internship experience and high self-efficacy to prepare them to enter the workplace after graduation.
