As part of the national education monitoring, the ÜGK/COFO/VECOF (i.e., the Assessment of the Achievement of Basic Competencies) is a large scale assessment (LSA) using computer-assisted classroom tests to assess the extent to which basic competencies (as defined by the national educational goals, see EDK, 2011) are achieved at the end of a cycle . Results, expressed as percentages of students meeting national educational goals, serve as indicators of cantonal and national education system performance. The assessment ÜGK/COFO/VECOF 2023 measured language competence in the local school language (German, French, or Italian), as well as in the first and second foreign languages (another national language or English). The main objective was to assess whether or not a student has achieved the desired language competence. Additionally, students completed a questionnaire assessing contextual variables (e.g., motivation, home language, and learning strategies).
