The purpose of this study was to investigate Chinese university professors' perceptions about the ethicality of classroom assessment practices. In a survey of Chinese professors, participants completed a questionnaire with 15 scenarios that depicted ethical and unethical assessment practices. Participants consisted of 555 professors from 143 universities located in 29 provinces in China. Overall, professors had high agreement about the ethicality of assessment practices with assessment experts on six scenarios, moderate agreement on five scenarios, and low agreement on four scenarios. Results indicated that ethical issues should be discussed according to the context of assessment. Additionally, developing guidelines of ethics in assessment should involve stakeholders, policy makers, administrators, researchers, and instructors.
