Prior research has suggested that staff-centred organisational factors such as participation, morale and shortage can have a significant effect on organisational outcomes. However, relatively little attention has been paid to cross-country examination of these relationships specifically for educational organisations such as schools, colleges, and universities. In this study we looked at the link between staff-centred organisational factors and organisational performance, within the special context of high schools across nationally representative samples from 64 countries and economies. Our empirical results indicate large cross-country variations in the effect of factors such as staff participation, morale and shortage, on school performance. Implications are discussed.
