The study aims to map the maturity of career guidance and counseling students which includes self-appraisal ability, work information, goal selection ability, planning ability, and skill in solving problems related to career development tasks. In approach, it used the explorative-descriptive research model. Involved as research subjects were students of the Graduate Study Program of Guidance and Counseling, Faculty of Education, Yogyakarta State University (YSU). The conclusions that could be drawn are as follows: 1). the career maturity level of guidance and counseling students is moderate in category (since M=72.42), with the students included in the moderate category being 69.3%, 2). The great percentage in "the middle category" is a group which is quite vulnerable in experiencing instability in career maturity if not well intervened/facilitated, and 3). there is no significant difference in career maturity among students' batches of different years entrance (since F=0.855 with Sig.=0.427).
