Texas Teacher Evaluation and Support System (T-TESS)

The Texas Teacher Evaluation and Support System (T-TESS) focuses on providing continuous, timely and formative feedback to educators so they can improve their practice. This is the state adopted model for teacher evaluation. In order to be a certified evaluator using this system, one must complete the following:  a 3 day T-TESS training and either Instructional Leadership Development (ILD) or Advancing Educational Leadership (AEL).


Advancing Educational Leadership (AEL)

Administrators must be knowledgeable in curriculum and instruction, must be skillful in data gathering and analysis, must be able to set goals, must be skillful in conducting effective conferences, must have team building skills and conflict resolution skills, and must have mentoring and coaching skills.   The Advancing Educational Leadership (AEL) training addresses all of these skills and provides practical tools for participants to implement.  This 3 day, researched based and engaging training is now required for teacher appraisers who are T-TESS evaluators unless you are already ILD certified.


Texas Principal Evaluation and Support System (T-PESS)

The intended purpose of the Texas Principal Evaluation and Support System (T-PESS) is to assess the principal’s performance in relation to the Texas Principal Standards. This is the state adopted evaluation model for Principals and in many districts for Assistant Principals as well. In order to be an evaluator for T-PESS, a 1 day face to face training must be completed.  


Guidance on Student Growth in T-PESS and T-TESS

The Student Growth Guidance documents from TEA on both T-TESS and T-PESS (links below) are designed to give you further clarification on the options for Student Growth within evaluation.

Student Learning Objectives Training (SLO)

The focus of this training is on Student Learning Objectives (SLOs), one option for measuring Student Growth as part of T-TESS or a locally developed appraisal system. The Student Learning Objective (SLO) Model in Texas provides a framework for continuous dialogue between students, teachers, and principals to support teacher development and student growth throughout the year.  In this training you will understand the SLO process, the value of the SLO process, the pedagogical questions are addressed through SLOs, and how SLOs fit within the broader goals of teacher appraisal. Finally, we want to provide a framework for districts and schools to begin planning for implementation.
