A conducive school environment is important to health and learning. This necessitated the inclusion of Healthful School Environment (HSE) component into the Nigerian National School Health Policy (NSHPo) of 2006, as part of the School Health Programme (SHP). This work focuses on HSE implementation compliance by the school street-level bureaucrats (school owners, teachers and the entire school community) to the provision of the NSHPo. Methods: This was a descriptive cross-sectional study which utilized a multi-stage sampling technique to select 42 primary schools in Ondo State as the study sample. An observational checklist was used to assess the HSE component of the SHP for compliance with the NSHPo provision. Implementation performance was determined by exploring the availability, suitability, appropriateness for use of specific items of the HSE component. Results: Out of the maximum obtainable score of 60, the schools had a mean score of 38.29± 10.132 (private schools scored 40.0± 10.602 while public schools scored 35.5± 8.940). A statistical significant relationship was found between school type and size of the ground (p= 0.006), school type and type of toilet facility (p= 0.020), and school type and cleanliness of the toilet facilities (p= 0.006). Conclusion: These research findings underscore the fact that the school street-level bureaucrats must and should be involved in every stage of the development of any school-based policy. The HSE implementation performance in the study area was generally above average. Some very important items like water and sanitation, which directly affects the health and safety of the entire school community, is either poorly implemented or completely missing. It is, therefore, recommended that the government should provide the schools with copies of the NSHPo, and provide them with the needed orientation regarding the provisions of the document
