All administrators who are responsible for evaluating teachers MUST be credentialed prior to using the Teacher Keys Effectiveness System (TKES). Credentialing is a process of establishing the qualifications and proficiency of evaluators to utilize TKES. The credentialing assessment is a minimal competency assessment that measures participants' understanding of the information and practice provided during training. It includes both recall of specific TKES information and practice of the TKES process. It is a bridge to ongoing learning as evaluators work with TKES. ALL evaluators MUST pass the credentialing assessment prior to using the Teacher Keys Effectiveness System. The expectation is that evaluators continue to familiarize themselves with the TKES instrument as they work within their districts.
