Ethical dilemma case-based examination (ethics Script Concordance Test, eSCT) is a written examination that can be delivered to a large group of examinees for the purpose of measuring high-level thinking. As it accommodates for diverse responses from experts, ethics SCT allows partial credits. The framework of ethics SCT includes a vignette with an ethical dilemma and a leading question, which asks the examinee to "agree" or "disagree", plus the shifts of prior decision by adding new information. In this article, the following tips for constructing this type of examination are provided: use "true" dilemmas, select an appropriate ethical issue, target high-level cognitive tasks, list key components, keep a single central theme, device quality scoring system, be important and plausible, be clear, select quality experts, validate, know the limitation, and be familiar with test materials...
