This article examined the extent to which leadership strategies to enhance school effectiveness were employed in selected secondary schools in Jamaica. Attention was placed on leadership strategies as these relate to decision-making, instruction and the learning environment. The sample of 35 principals was selected by stratified random sampling from 14 Reclassified High, 7 Junior High and 14 All Age Schools. A questionnaire was used in the collection of data. The findings revealed that while the selected leadership strategies were employed in the schools little attention was given to the extent to which parents participated in school decision making. There was no significant difference in opinion between principals with formal training in Educational Administration and those without formal training, on the extent to which leadership strategies were employed to enhance school effectiveness.
