Ohio Rev. Code § 3319.25
Any teacher performance assessment entity with which the department of education and workforce or the state board of education contracts or any independent agent with whom such entity, the department, or the state board contracts to provide services as a teacher performance assessor, trainer of assessors, or assessment coordinator is not liable for damages in a civil action concerning the actions of such entity or agent made in the conduct of a teacher performance assessment unless those actions were conducted with malicious purpose, in bad faith, or in a wanton or reckless manner.
As used in this section, "teacher performance assessment" means an assessment prescribed by the state board of education to measure the classroom performance of a teacher who is a candidate for licensure based on observations conducted by a trained assessor while the teacher is engaged in actual classroom instruction.
