This study aims to examine and prove the factors that affect the optimisation of facilities and infrastructure in vocational high schools. The research design used is a quantitative research method. The study was conducted at vocational high schools. The research sample used was 125 teachers in vocational high schools. Data collection techniques were carried out using a questionnaire. Data analysis was carried out using descriptive statistical analysis and multiple regression analysis through t-test. The results of this study indicate that there is a significant effect on the optimisation of facilities and infrastructure for the rule factor, partnership factor, student needs factor and motivation factor. The findings of this study prove that the optimisation of facilities and infrastructure is very important to be developed and implemented in vocational high schools.           Keywords: Educational facilities and infrastructure, vocational high schools.

The research aims to know the factors that influence optimizing vocational high school facilities and infrastructure. By optimizing vocational high school facilities and infrastructure, it becomes strategic enough to contributeto the administrative performance, quality of learning, and quality of graduates. The research used a quantitative approach using questioners as the instruments of data collection with several 124 respondents.The analysis technique used a multiple regression test with one dependent variable and four independent variables. The results of the research conclude that the factors of student need (ρ = 0,016) and motivation (ρ = 0,024) significantly influence while the factor of rule (ρ = 0,169) and partnership (ρ = 0,108) do not significantly influence the optimization of facilities and infrastructures in Vocational High School.The four factors have a significant effect on ρ = 0,000.
