In this workshop we will detail strategies for identifying and mitigating the effect of scoring bias in SPs and raters. We will review interactive approaches to engaging the raters in identifying what biases may affect their own scoring. The workshop will also review how a systematic review of rater scores may indicate the presence of bias or other issues, e.g. carelessness in scoring or the need for additional training. The workshop facilitators will also engage participants in sharing their experiences in bias reduction training.
