Teacher Keys Effectiveness System (TKES)


Every child in every community deserves excellent, effective classroom teachers.  That is why Georgia developed the Teacher Keys Effectiveness System (TKES) to provide teachers with more meaningful feedback and support so they can achieve the goal of increasing academic learning and achievement for all students. We believe students have the greatest chance to succeed when teachers receive support to continuously improve their knowledge and skills. Ongoing feedback and targeted professional development help teachers meet the changing needs of their students. We believe TKES provides teachers with meaningful information about how their practice and performance impact student learning. TKES acknowledges the central role of teachers and provides the opportunity to refine their practice to continually and effectively meet the needs of all students.



Components of the Teacher Keys Effectiveness System (TKES) The Teacher Keys Effectiveness System (TKES) is comprised of three components which contribute to an overall Teacher Effectiveness Measure (TEM): Teacher Assessment on Performance Standards (TAPS), Professional Growth, and Student Growth.  

Teacher Assessment on Performance Standards (TAPS): (50%)

  • TAPS provides evaluators with a qualitative, rubrics-based evaluation method by which they can measure teacher performance related to quality Performance Standards.
  • Observations by a credentialed evaluator shall inform the Summative Performance Evaluation each year.
  • All ten Performance Standards shall be rated on the Summative Performance Evaluation.
  • Teachers are permitted to use the school district’s local complaint process to file grievances related to procedural deficiencies on the part of the local school system or charter school in conducting TKES evaluations. A teacher’s performance rating(s), professional growth goal(s) and/or plan(s), and job performance cannot be disputed through the complaint process.


Professional Growth(20%)

  • Professional Growth may be measured by progress toward or attainment of Professional Growth Goals. These goals may or may not be reflective of the Professional Learning Goals or Professional Learning Plans as defined by the Georgia Professional Standards Commission (GaPSC).


Student Growth: (30%)

  • Student Growth Percentile Measures: For teachers of SGP grades and courses, this component is comprised of a Student Growth Percentile which shall be calculated annually for student growth based on state assessment data.
  • LEA Determined Measures: For teachers of non-SGP grades and courses, this component is comprised of LEA Determined Measures which may be Student Learning Objectives, the School or District Mean Growth Percentile, or another measure identified or developed and implemented by the LEA.
  • Student Growth data shall be a lagging measure; when available, the prior year’s growth measures will inform the current annual Summative Performance Evaluation.
