Subd. 1. Supervision of school building.
Each public school building, as defined by section 120A.05, subdivisions 9, 11, and 13, in an independent district may be under the supervision of a principal who is assigned to that responsibility by the board of education in that district upon the recommendation of the superintendent of schools of that district. If pupils in kindergarten through grade 12 attend school in one building, one principal may supervise the building.
Subd. 2. Valid license required.
Each principal assigned the responsibility for the supervision of a school building shall hold a valid license in the assigned position of supervision and administration as established by the rules of the commissioner of education.
Subd. 3. Duties; evaluation.
(b) To enhance a principal's culturally responsive leadership skills and support and improve teaching practices, school performance, and student achievement for diverse student populations, including at-risk students, children with disabilities, English learners, and gifted students, among others, a district must develop and implement a performance-based system for annually evaluating school principals assigned to supervise a school building within the district. The evaluation must be designed to improve teaching and learning by supporting the principal in shaping the school's professional environment and developing teacher quality, performance, and effectiveness. The annual evaluation must:
(9) for principals not meeting standards of professional practice or other criteria under this subdivision, implement a plan to improve the principal's performance and specify the procedure and consequence if the principal's performance is not improved.
The provisions of this paragraph are intended to provide districts with sufficient flexibility to accommodate district needs and goals related to developing, supporting, and evaluating principals.
