The Teacher and Principal Evaluation and Growth Program (TPEP) is based on these core principles:

  • High quality teaching and leading are key to student success.
  • Growth in practice is developmental in nature.
  • Growth occurs best when there are clear standards of practice supported by quality professional learning and learning-focused feedback.
  • Evaluation systems should reflect and address the career continuum.
  • The focus for teacher and principal growth should be driven by student learning needs.

Evaluation Guidance for 2023-24

For information and guidance on following the established evaluation procedures, please consult Bulletin 040-23 and consult the TPEP FAQ page. Of particular note this year would be the following, which are detailed in the Bulletin:

  • Effective August 1, 2023 evaluations and summative conference for principals and assistant principals must be conducted by the evaluator prior to June 1 of that school  year. For more information, please consult the amendatory sections of WAC 392-191A-160 and WAC 392-191A-190.
  • The 2023-24 school year is the final year that districts can elect to use the 2011 version of the Danielson Framework for Teaching. Beginning with the 2024-25 school year, the updated Danielson Framework for Teaching (2022) will be required for use for evaluation purposes for districts who use this instructional framework. For information and resources please visit the Danielson Framework page.
  • The 2023-24 school year is the final year that districts can elect to use the original Student Growth Goals for evaluation. Beginning with the 2024-25 school year the Final Revised Student Growth Goal Rubrics will replace the existing rubrics for use in evaluation. For more information and resources, please visit the Student Growth page.

eVAL will be undergoing a process to make the platform ADA compliant. Under the advisement of the TPEP Steering Committee, OSPI is convening a technical advisory committee to provide input and guidance on the work of making eVAL ADA compliant. Districts will continue to have access to eVAL in its current form while the work of transitioning occurs. Once we have a clear timeline and transition plan, we will communicate it via GovDelivery and a Bulletin.
