RESA assessors receive extensive training on the RESA Lesson Reflection. Their training includes a module on recognizing and minimizing bias, in addition to comprehensive modules on each of the seven evaluation domains in the Lesson Reflection. Once assessors pass the certification test, they are assigned submissions to score.
Assessors are prohibited from scoring submissions of candidates they might know, and they are asked to defer submissions of candidates whom they recognize.
For quality assurance purposes, master scorers check assessor quality by conducting reviews of the assessor’s scoring. Assessors who do not meet a minimum accuracy standard are not permitted to score.
