In the face of an increasingly strong and competitive globalization era, implementation of Integrated Quality Management System (IQMS) in the vocational schools is very important for the long-term success of school organizations and is a source of excellence in order to create performance and productivity towards achieving continuous quality management. This study aimed to describe: (1) the implementation of IQMS in the State Vocational High School in Samarinda based on school quality management; (2) the level of achievement of IQMS at State Vocational School in Samarinda according to school quality management; and (3) the obstacles of IQMS implementation in the state vocational high school in Samarinda. This study used a qualitative descriptive design and selected one of the state vocational high school in Samarinda that implemented the IQMS, i.e. SMKN 7 Samarinda. The structured interview and library reseach used to explore information about the implementation, level of achievement, and the obstacles that the school faced during IQMS implementation. The results showed that: (1) the IQMS implication in the SMKN 7 Samarinda had been implemented according to the IQMS indicators; (2) the level of achievement of IQMS implementation in the SMKN 7 Samarinda reach the good criteria with increasing number of students and increasing educators' competency, teaching and learning facilities and infrastructures, and established a conducive work and learning environment; and (3) the obstacles to the IQMS implementation in the SMKN 7 Samarinda, i.e. some teachers still lack to use technology in the learning process and often used traditional way to teach, and lack of commitment in quality assurance from the internal school.
