Step-by-step explanation:
The correct option : b
According to the Republic Act 9155, otherwise known as the Governance of Basic Education Act of 2001, the component considered as the "heart of the formal education system" is B) Teacher Performance Assessment. This aspect of educational governance in the Philippines emphasizes the central importance of teacher quality and performance in achieving effective learning outcomes.
Teacher performance assessment is pivotal because teachers are directly responsible for the delivery of instruction and the facilitation of learning. The law recognizes that the quality of teaching is the most significant school-based determinant of educational outcomes. Therefore, it aims to establish high standards for teachers, promote their professional development, and assess their performance to ensure that students receive the best possible education. Teacher evaluations are critical for understanding the impact of instructors on student achievement and for guiding their ongoing professional growth and development.
