This exploratory study involved a structured group-games intervention to develop first-grade students’ social competence. The effects were evaluated by assessing possible outcomes for the children's social status. A sample of 119 first-grade, mixed-ability students from a Hong Kong primary school participated in the sessions (63 boys, 56 girls: mean age 74 months). Sessions were led by trained parent-volunteers and involved a 60-minute session each week for 8 weeks in the children's own classrooms. Peer nominations were used before and after intervention to assess participants’ social status under five possible categories ― popular, rejected, controversial, neglected and average. Improvement in children's social awareness and social status was noted following the intervention. Children's competence in playing group games was found to be positively correlated with their social acceptance. The findings support the value of early social intervention in classrooms as a practical way for preparing first-grade students for primary school life.
