Value-Added Model Evaluation For Teacher Accountability

An evaluation of leading applications of Value-Added Models (VAM) for measuring teacher effectiveness. The analysis clarifies questions raised by VAM use and discusses statistical and measurement issues affecting inference validity. It was authored by Daniel F. McCaffrey, though its publication date is unknown.

Use Cases

• Analyze the correlation between VAM scores and other teacher effectiveness metrics like classroom observation ratings.
• Assess the impact of student demographic features, such as prior test scores or socioeconomic status, on VAM estimates.
• Evaluate the stability of teacher value-added scores across different academic years or subject areas.
• Investigate statistical issues like measurement error or model bias within VAM outputs for policy recommendations.

Strengths

• Focuses on a critical and widely debated methodology in education accountability.
• Provides a structured discussion of multiple statistical and measurement validity issues.

Limitations

• The dataset or underlying analysis data is not provided, limiting reproducibility.
• Specific sample sizes, model parameters, or empirical results are not detailed.
• The publication date and temporal context of the evaluation are unknown.
