Scoring the Ohio RESA is an opportunity for administrators, teacher leaders, and university faculty to understand how Resident Educators are developing their craft and to assess their instructional practices based on the Lesson Reflection domains, which were developed from the Ohio Standards for the Teaching Profession. Assessors must have a minimum of 10 years of teaching experience in a pre-K–12 setting. To become an assessor, you must meet RESA recruiting needs, participate in online training, and pass the certification test.
