The role of the school principal has changed much in the recent intervening years. He/she was formerly thought of as a manager and management of the local school. Today the principal is seen as the leader of curriculum improvement. School principals must believe in pupils being able to achieve optimally in school and in life. Principals must become self efficacious in knowledge and skills in curriculum development.

Examples in reading, mathematics, science, and social studies are listed in this article. A list of inservice education opportunities for all teachers, as well as the principal self involvement in acquiring self efficacy is provided.
