Which of the following is the objective of a teacher?

Teaching-aptitude theory (per the NCTE teacher-education framework) holds that a teacher's professional purpose is learner-centred: the core responsibility of a teacher is to promote the all-round welfare and development of students, not personal recognition or the sheer volume of students taught.

Applying this principle here, the objective that extends student welfare to the possible maximum limit places the learner's holistic growth at the centre of the teacher's role — exactly what the teaching profession is built around.

• To gain possible maximum fame ties the purpose of teaching to the teacher's own personal recognition, which is self-serving rather than learner-centred.

• To teach the possible maximum number of students measures the objective by headcount and coverage volume, ignoring the depth or quality of each student's development.

• None of these would only be correct if no offered goal matched the recognized objective of teaching; since one of them does capture it, ruling out every option is not warranted.

Hence, extending the welfare of students to the possible maximum limit is the recognized professional objective of a teacher.
