Early childhood intervention is intended to systematically network and customise support services, particularly for socio-economically disadvantaged families. The programmes are universal or selective, but the evidence on their effectiveness is limited.

The aims of this study were to exemplary analyse whether participants in early childhood intervention services had better development than non-participants using the school entry examination (SEE) as well as to discuss to what extent the SEE can be used to assess the impact of early childhood intervention services.

We analysed three typical offers of early childhood intervention services (family education; Zukunft für Kinder (ZfK); Kita-U) in relation to full vaccination coverage and age-appropriate development at U9. Data from 4579 Düsseldorf first graders were included. Propensity score matching was used to calculate percentage differences (average treatment effect on the treated; ATT) in terms of immunisation coverage and development between comparable intervention and control groups.

All programmes are associated with a slightly increased probability of full vaccination protection (ATT 2.1 for family education; 2.5 for ZfK; 5.3 for Kita-U). Family education is also associated with a slightly higher probability of age-appropriate development (ATT 1.6), while the probability of age-appropriate development is lower for participants in ZfK (−10.1) and Kita‑U (−4.5).

The evaluation of early childhood intervention, especially selective services, is a methodological challenge due to confounding and suitable comparison groups. However, the SEE could be a framework for impact analyses under specific conditions.
