Summary
The study tested Fiedlér's contingency theory by examining the relationship between Lebanese secondary school principals' style and school outcomes. The findings support the Least Preferred Co-worker instrument as a discriminatory tool and demonstrate the existence of significant predictive relationships between high LPC scores and students' achievement in high and moderate control situations. No support is provided to Fiedler's interpretation of the LPC instrument as a measure of a hierarchy of motives nor to Fiedler's LPC/situational-control match concept.
