Tietotaso

Tietotaso is a Finnish noun that refers to the level, degree, or quality of information or knowledge. It is formed from tieto, meaning information or knowledge, and taso, meaning level or tier. The term is widely used in both everyday language and more technical contexts, and its exact meaning depends on the field of use.

In information management and data governance, tietotaso describes how detailed, complete, and reliable the information in a system or dataset is. A higher tietotaso typically implies more granular, richer, or more accurate data, while a lower tietotaso indicates more summarized or uncertain information. In organizational discussions, tietotaso can also refer to the maturity of information processes and practices, such as documentation quality, data stewardship, and governance capabilities.

In human knowledge contexts, tietotaso denotes a person’s level of knowledge or competence in a subject area, often described qualitatively (for example, low, medium, or high) or described through specific skills and qualifications. The term is thus versatile and context-dependent, without a single universal scale.

Common phrases include tietotason arviointi (assessment of information level), tietotason hallinta (management of information level), and combined discussions with related concepts such as tietoturva (information security) and tietohallinto (information management). Because it is broad, the term is typically clarified by accompanying descriptors indicating the relevant domain and scale.
