What is a primary responsibility of a principal regarding staff development?

A primary responsibility of a principal regarding staff development is to provide ongoing training. This encompasses creating opportunities for professional growth, ensuring that teachers and staff members have access to current educational practices, resources, and skills necessary for effective teaching and administration.

Principals play a vital role in fostering a culture of continuous improvement within their schools, which can include workshops, professional learning communities, and individualized coaching sessions. Ongoing training not only enhances the teachers' effectiveness but, ultimately, it leads to improved student outcomes and a more supportive learning environment.

The other options pertain to responsibilities that, while important for the overall functioning of a school, do not focus specifically on the development and support of staff. Evaluating bus schedules, monitoring student lunches, and enforcing discipline are operational and managerial tasks that are necessary for school logistics and discipline but do not directly pertain to the professional growth and development of the staff.
