Purpose: The purpose of this paper is to report findings from an investigation of Greek principals' attitudes and perceptions concerning parental involvement in schools--research prompted by the belief that the information will be useful in attempts to make Greek schools more effective. Design/methodology/approach: The participants of the study were secondary school principals and vice principals from one Prefecture in Central Greece. The questionnaire used elicited information about the participants' demographics, the main features of the schools they were serving in, and their views concerning existing and preferred school-family partnerships. Findings: The principals in the investigation seemed to be not only in favor of parental participation, but also saw a need to increase it. In general, then, the findings support others' reports that parents' participation in schools--in this instance secondary schools--tends to be less than satisfactory. Originality/value: In Greece, the issue of parental involvement in schools has not received adequate attention until recently. The latest school reforms emphasize the notion of parental involvement as a significant factor for the effectiveness of the Greek schools.
