Crafting Effective Teacher Evaluations: Best Practices for Principals and Educational Leaders
June 10th, 2024
By Héctor Navedo, Ed.D.
Introduction
Teacher evaluation should connect evidence, feedback, and opportunities for professional development. This article proposes a professional framework for local review, not a validated evaluation instrument. A Stanford report argues for connecting evaluation with support for effective teaching (Darling-Hammond, 2012). An administrator-training field experiment examines feedback quality in evaluation systems (Kraft & Christian, 2022). These sources inform the emphasis on feedback and support; they do not validate every procedure proposed below.
Understanding Evaluation
Evaluation is a systematic and objective process for determining the value or merit of an object, individual, or program through the collection and analysis of data. In the educational context, evaluation applies to various facets, including the performance of teaching and non-teaching staff, curricular programs, and educational systems.
Types of Evaluation
Evaluation of Teaching and Non-Teaching Staff
Evaluation of Teaching Staff: Review evidence about instruction, classroom practice, and professional development against clearly communicated criteria.
Proposed purposes of evaluation:
Improving teaching and learning.
Identifying areas for professional development.
Recognizing and rewarding excellence.
Professional principles proposed for local review:
Equity and Transparency: Utilizing multiple data sources and methods, avoiding over-reliance on standardized tests.
Relevant Evidence: Consider classroom observations, self-evaluations, student work, and student feedback, while reviewing the limitations of each source.
Focus on Professional Development: Linking evaluations to personalized professional development opportunities.
Evaluation of Non-Teaching Staff: Adapt evaluation criteria to the responsibilities of each role; do not assume that a teacher-evaluation model fits every school employee.
Curricular Evaluation
Curricular evaluation examines the relevance of content, methods, and materials to educational objectives and student needs. I recommend defining the questions and evidence before selecting evaluation tools.
Program and System Evaluation
Program Evaluation: Define the objectives of an intervention, extracurricular activity, or support program, then select evidence that can inform whether it is meeting those objectives.
System Evaluation: This refers to the comprehensive evaluation of educational systems at an institutional or national level. It involves reviewing educational policies, organizational structures, and administrative practices to identify areas for improvement and promote the efficiency and effectiveness of the overall educational system.
Principles of Responsible Evaluation
Equity and Transparency
Do: Use more than one relevant evidence source and communicate the criteria and process to teachers. Review whether the evidence fairly represents the work being evaluated.
Please do not rely solely on standardized test scores, as they may not accurately reflect a teacher's overall performance and can introduce bias.
Evidence-Based Evaluation
Do: Use relevant evidence and examine its quality and limitations. Consider classroom artifacts, student work, and observations rather than treating any measure as automatically objective.
Do not: Make judgments from unverified assertions. Specify the framework and examine its suitability for the intended use.
Focus on Professional Development
Do: Link evaluations to personalized and contextualized professional development opportunities. Provide actionable feedback and support to help teachers improve their practice.
Do not: Use evaluations punitively or without follow-up support. Avoid creating a high-stakes environment where teachers feel threatened or demotivated by the evaluation process.
Innovative Evaluation Models
Collaborative-Based Evaluation
Do: Promote the active participation of teachers in the evaluation process. Encourage reflection and professional dialogue to foster a collaborative culture.
Do not: Implement top-down evaluation models that exclude teachers' voices and perspectives. Avoid making decisions without involving those who are being evaluated.
Use of Technology in Evaluation
Do: If digital tools are used, choose them for a defined evaluation need, train users, and review workload and data quality. Technology alone does not establish the effectiveness of an evaluation process.
Keep digital evaluation procedures simple, provide training, and review whether the tools create unnecessary work.
Holistic and Inclusive Evaluation
Do: Consider various dimensions of teaching, including pedagogy, content knowledge, and impact on student well-being. Include metrics that evaluate the learning environment and school culture.
Do not: Focus narrowly on academic outcomes alone. Avoid ignoring teachers' broader contributions to the school community and student development.
Implementation and Policies
Support Policies and Resources
Do: Advocate for time and space for teacher collaboration and access to professional development programs. Ensure that policies support a conducive environment for growth.
Do not: Implement policies that create excessive administrative burdens or limit opportunities for meaningful professional development.
Evaluator Training
Do: Provide evaluator training and opportunities to review criteria and compare judgments. Assess whether that preparation supports the intended evaluation process.
Do not: Allow untrained evaluators to conduct assessments. Ensure that all evaluators understand the evaluation criteria and procedures.
Stakeholder Involvement
Do: Invite relevant teacher, student, and family perspectives when designing and reviewing evaluation procedures. Clarify how those perspectives will be used.
Make stakeholder participation meaningful by explaining decisions and the reasons for them.
Continuous Improvement
Do: Review the evaluation system regularly using feedback and evidence about its operation. Revise procedures when the review identifies a reason to do so.
Keep the evaluation system from becoming stagnant. Avoid resisting changes that can enhance the evaluation process.
Balanced Approach
Do: Balance accountability with professional support. Specify both expectations and opportunities for development.
Do not rely on accountability measures without adequate professional support.
Reviewing Principal-Led Evaluation
Five Risks to Review
Over-reliance on Test Scores: Ask whether the evidence captures relevant dimensions of teaching rather than reducing the judgment to test results.
Evaluator Preparation: Review whether evaluators understand the criteria and have opportunities to calibrate their judgments.
Feedback and Follow-up: Check whether feedback is specific and whether teachers can access the support needed to act on it.
Teacher Input: Create a meaningful opportunity for teachers to discuss the evidence, explain context, and respond to feedback.
Evidence Coverage: Examine what each evidence source captures and what it leaves out.
For a proposed pilot with explicit safeguards and decision rules, see teacher evaluation and professional learning.
Conclusions and Recommendations
I advocate evaluation that is equitable, transparent, and connected to professional development. Schools should examine how their procedures operate in practice rather than assume that adopting this framework will improve outcomes.
Ten Professional Recommendations for Local Review
Integrate Formative and Summative Assessments: Combine both types of assessments to provide comprehensive feedback and measure long-term progress.
Encourage Self-Reflection: Incorporate self-assessment opportunities for teachers to reflect on their practices and identify areas for improvement.
Implement Peer Reviews: Foster a culture of collaboration by having teachers observe and provide feedback to one another.
Use Student Feedback: Collect and analyze student feedback to gain insights into teaching effectiveness and classroom climate.
Regularly Update Evaluation Criteria: Ensure that evaluation criteria are current and aligned with best practices and educational standards.
Provide Professional Development: Link evaluation outcomes to targeted professional development opportunities to address identified areas for growth.
Create a Supportive Environment: Establish a supportive school culture where teachers feel safe to take risks and innovate.
Focus on Instructional Quality: Prioritize evaluating and improving instructional practices rather than solely focusing on student outcomes.
Engage in Continuous Dialogue: Maintain open lines of communication between evaluators and teachers throughout the evaluation process.
Evaluate the Evaluation System: Regularly review and assess the effectiveness of the evaluation system itself to ensure it meets its goals and supports teacher development.
