Requires school districts to use student growth data to create: (1) A rank order of teachers based on the amount of average student growth achieved in each teacher's classroom; and

(2) A rank order of principals based on the amount of average student growth achieved by the teachers in each principal's school.

Requires one of the multiple measures of student growth, for certain teachers and for certain principals, to be student results on relevant assessments.

Requires seniority to only be used as a tiebreaker when determining how multiple factors will be used in making certain human resource or personnel decisions.
