Effective school management entails the establishment of systems and procedures that facilitate the learning process (Putra et , 2. Education is crucial in human life since it possesses the ability to provide hope and elevate an individual's quality of life in the future, as stated by Silalahi .

Unquestionably, this has an adverse effect on education and frequently leaves the public feeling let down (Silalahi, 2. According to Syamsul . , good head of school leadership should promote teacher effectiveness through staff development. A leader can start by being loving.
