Because T-PESS is an evidence-based process, it is imperative that the appraiser and principal must collect and prioritize evidence throughout the year. Each indicator of the T-PESS rubric provides numerous examples of artifacts and evidence. The appraiser should be intentional about conducting school site visits to collect pertinent evidence, including the impact on systems, processes, teacher performance, student outcomes, and including the implications on the larger system.
Principals and appraisers synthesize their collected artifacts and evidence, to create a comprehensive view of the principal's performance throughout the year. This brief summary is not intended as a portfolio, but rather a concise review of information that may be used as consideration for performance and ratings during the end-of-year conference. T-PESS evidence is collected using four comprehensive strategies:
- Purposeful observations and walk-throughs tied to principal practices.
- Ongoing and purposeful data collection tied to the systems and processes within the campus.
- Artifacts and/or evidence tied to the domains, indicators, and descriptors in the rubric.
- Other performance data regarding the campus and its operational systems and processes, staff, students, and parent/community stakeholders.
The principal may be asked to provide the summary evidence to the appraiser in advance of the EOY meeting, as specified in local policy or procedure, or as requested by the appraiser.
