Uganda has received considerable international attention for being the first and, to date, only African country to adopt a policy of free universal secondary education (USE). However, the policy was adopted with little attention to system capacity or involvement of secondary head teachers, even though there is considerable research documenting the importance of school leaders in promoting or blocking education reform efforts. This study investigated the extent to which Uganda secondary school leaders support USE policy, the extent they think USE is being implemented successfully, and the extent they believe they have the knowledge and skills needed in USE implementation. To understand the role of head teachers in the move to USE in Uganda, it is necessary to understand the political context in which it was adopted and the conditions under which it was implemented.
