Basic level 1F96%97%96%
Target level 1S/2F63%64%58%
  • Performance thresholds for this school: 85% (1F) and 49,4% (1S/2F). Results: 1F above the performance threshold, 1S/2F above the performance threshold.
  • By school year: 2023/24: 1F 100%, 1S/2F 71% (n=7) · 2024/25: 1F 94%, 1S/2F 48% (n=11) · 2025/26: 1F 96%, 1S/2F 75% (n=8).
  • School weighting: 27,1 (national average approximately 30; the scale runs from 20 to 40). A lower weighting means pupils' parents have a higher average level of education, so the Inspectorate expects better results. Average in Groningen: 26,7.

DUO does not publish counts below 5; these are excluded here.
  • Inspectie van het Onderwijs: primary school learning outcomes (percentage of pupils at reference levels 1F and 1S/2F, three-year averages, and thresholds by school weighting) and school weighting (CBS). The rating comes from the register of inspection ratings; "Standard supervision" is not a rating.
  • School recommendations: the final recommendation for secondary education, including revisions following the primary school transition test. Combined recommendations (such as vmbo-kader/gl-tl) are split equally between the two levels.
  • Comparisons with the municipality and the Netherlands are calculated by Huisleon as pupil-weighted averages across all schools of the same type. Data on where pupils continue their education after leaving this school is not openly available; see Scholen op de kaart for this information.
