Generally, a distinction is made between two types of intervention activities: those which are conducted at home (family-based activities) and those which are conducted in, for example, preschools (center-based activities). This research project tries to establish whether there is a relation between participation in early intervention activities and the educational achievements of 119 pupils from the cities of Tilburg and Waalwijk. A comparison is made between four groups of children: a group that took part in the family-based program Opstap Opnieuw, a group that went to preschool, a group that did both, and a control group. The performances of these four groups are followed during the first years of primary education. In addition, an estimate is made of the influence of family characteristics on the effectiveness of both types of intervention activities., language=, type=
