The understanding of teachers' perception of new educational policy is crucial since this perception shapes the policy's implementation. However, quantitative research in this area is scarce. This article draws on empirical data to investigate whether the school leader might influence his teachers' perception of the new teacher evaluation policy. The conceptualisation of teachers' perception consists of three policy characteristics: practicality, need and clarifying function. Our results indicate that school leadership influences teachers' policy perception. More specifically, the structure a school leader provides in a school and the amount of trust teachers have in the school leader have a significant impact on teachers' perception of the practicality of the new teacher evaluation policy.
