Results
Group 8 doorstroomtoets
The proportion of pupils achieving the basic level (1F) and target level (1S/2F) in reading, spelling and grammar, and maths, averaged over three school years. The Inspectorate compares these results with a performance threshold based on the school's pupil population.
- Performance thresholds for this school: 85% (1F) and 30,2% (1S/2F). Results: 1F above the performance threshold, 1S/2F above the performance threshold.
- By school year: 2023/24: 1F 93%, 1S/2F 53% (n=40) · 2024/25: 1F 96%, 1S/2F 32% (n=34) · 2025/26: 1F 94%, 1S/2F 30% (n=35).
- School weighting: 36,1 (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 Schiedam: 32,2.

Sources and notes
- DUO open education data (CC BY 4.0): school location addresses, pupil counts by school location and year group, pupils' home postcode areas, secondary school track recommendations and revisions, average primary school transition test scores, exam candidates, passes and grades, and pupils repeating a year. 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.
