Data are important assets of organizations and define their businesses or functions. Data needs to be governed and controlled so that it goes to the proper owner. Well-defined data management can help organizations maintain the quality of their data. This study took the IT Bureau of Audit Board of State as a study research. The study assesses its maturity level and recommend how the board can benefit from learning it. This study used Stanford Maturity Model as the framework tool to assess practices of data governance in IT Bureau of audit board. The maturity assessment is performed by assessing both IT Bureau staffs and top echelons. After validation and finalization assessment, the result showed that most maturity components had average maturity level of 2.63. It means the IT Bureau of Audit Board already has high-level data governance meta-policies which are considered as best practices (between level 2 and 3). The data governance components that can be improved in the future are stewardship and metadata on capabilities dimension and policies dimension.
