Voluntary sampling was conducted to collect research data. Electronic survey sent to 600 Indonesia which was 504 filled the survey completely. The partial least square structural equation modelling (PLS-SEM) was employed to analyze the data. The results showed that integrated leadership directly affected teacher job satisfaction in a positive way. Teacher collaboration and professional development had positively affected teacher satisfaction in their job. It was figured out that teacher collaboration and professional development have partial mediation effect on the relationship between integrated leadership and teacher job satisfaction.
