London ISD uses T-TESS to evaluate teacher performance. Domain 2 (Instruction) and Domain 3 (Learning Environment) have been established as priority areas of emphasis by TIA. Based on statewide observations data, TEA has also identified minimum score averages as measured across both domains of T-TESS. More information can be found in TEA's Texas Teacher Evaluation and Support System (T-TESS) webpage.
*Please note that the new Acknowledged designation will apply to 2025–2026 school year data.
Teacher Observation Minimum Performance Standards
To implement the Teacher Incentive Allotment, House Bill 3 also requires the setting of “performance and validity standards” to ensure that the identification of highly effective teachers under the four designation categories –*Acknowledged, Recognized, Exemplary, and Master – yields reliable and comparable results across the state. The following shows the minimum average scores across T-TESS domains 2 and 3 to achieve each level of designation (Acknowledged, Recognized, Exemplary, and Master).
*Please note that the new Acknowledged designation will apply to 2025–2026 school year data.
T-TESS Domain/Dimension Scoring
Each dimension is scored on a 1-5 point scale as displayed in the below T-TESS Scoring chart. Domain 2 and 3 total score is determined by calculating the average of all dimensions across Domains 2 and 3 from a teacher's summative score. This information will be exported from DMAC.
To be eligible, teachers must earn a *3.5 or above in Domains 2 and 3.
*Please note that the new Acknowledged designation will apply to 2025–2026 school year data.
