Career self-efficacy, maturity, and readiness are the three concepts often associated with career planning. The study investigates the relationship between career self-efficacy, career maturity, and career readiness among students undergoing technical and vocational education training (TVET) in Terengganu. A total of 500 students from five training institutes were selected purposively as a sample. This research implemented cross-sectional data with the ordinary least square analysis method. Data were collected using three sets of instruments, namely career factors inventory (CFI) to measure career readiness, career maturity inventory-revised (CMI-R) to measure attitudes and skills in career planning, and career decision making self-efficacy scale (CDMSE-SF) to measure the level of career self-efficacy. The results confirmed that career self-efficacy has a positive relationship with career maturity, while career maturity and career self-efficacy are unrelated to career readiness. A few ideas have been proposed to help all institutions.
