TDES (Teacher Development and Evaluation System)

Teacher Development and Evaluation System (TDES) 

TDES is the Teacher Development and Evaluation System for the Cleveland Metropolitan School District. Based on the Charlotte Danielson Framework for Professional Practice, TDES has transformed an outdated employee evaluation checklist into a comprehensive system based on self-reflection, observation, feedback and a plan for growth. 

The teacher development focus of the TDES system provides opportunities for CMSD teachers to engage within the District in meaningful learning experiences to benefit every child in Cleveland. With focused professional development offered at buildings and at locations throughout the district, CMSD teachers dig deep into the Framework for Professional Practice (the TDES rubrics) to enhance the effectiveness of their teaching.

Frequently Asked Questions  

What is TDES? 

TDES is the Teacher Development and Evaluation System of the Cleveland Metropolitan School District. The Cleveland Teachers’ Union and CMSD have worked together to create a system for evaluating Cleveland’s teaching staff. Our model is informed by the research of Charlotte Danielson, a nationally recognized expert in education, and is founded on a research-based framework for evaluating four domains of teacher effectiveness. 

Why do teachers have to be evaluated in TDES? 

House Bill 153 was signed into law on June 30, 2011. This legislation makes changes to the teacher evaluation process throughout Ohio, not just in Cleveland. HB 153 requires that all Ohio school districts have new evaluation system in place by July, 2013. ODE has a good FAQ on HB 153 for more information. Additionally the CBA for Cleveland teachers includes TDES. 

What is OTES? 

OTES is the State version of TDES. It stands for Ohio Teacher Evaluation System. Our system, TDES, is aligned to OTES, but they are not identical. Evaluators must receive training in OTES in order to be state-certified evaluators. They take a computer-based test that they must pass in a proctored setting in order to conduct valid evaluations for the State of Ohio. 

Who will evaluate the teachers? 

The building principal will be the evaluator. In large buildings with assistant principals, the AP may do the evaluation instead. A CIS may also conduct evaluations. If you work under a teaching contract, but are not a classroom teacher, then your department head or supervisor will conduct your evaluation. 

Can teachers choose their evaluators? 

Generally, no. 

Will Teach for America teachers be evaluated using TDES? 

Yes. All CMSD teachers, including TFA teachers, will be evaluated using TDES. 

Are substitutes evaluated in TDES? 

No. The state does not require that we evaluate substitutes.
