(a) All school districts have two choices in selecting a method to appraise principals: a principal appraisal system recommended by the commissioner of education or a local principal appraisal system.(b) The commissioner's recommended principal appraisal system, the Texas Principal Evaluation and Support System (T-PESS), was developed in accordance with the Texas Education Code (TEC), §21.3541.(c) The superintendent of each school district, with the approval of the school district board of trustees, may select the T-PESS. Each school district wanting to select or develop an alternative principal appraisal system must follow the TEC, §21.3541, and §150.1026 of this title (relating to Alternatives to the Commissioner's Recommended Principal Appraisal System).(d) The commissioner may designate a regional education service center to serve as the T-PESS certification provider for the state. The designated regional education service center may collect appropriate fees under the TEC, §8.053, from school districts and open-enrollment charter schools for training and certification.(e) Sections 150.1022 through 150.1025 of this title apply only to the T-PESS and not to local principal appraisal systems.
