Abstract
To cultivate the students' ability of appropriate ethical judgments is a purpose of engineering ethics education. How to measure the ability of ethical judgments must be devised in order that the achievement of the purpose can be properly assessed. This paper proposes that three kinds of knowledge should be taught in an engineering ethics course because of the necessity for their making appropriate ethical judgments. And these three kinds of knowledge would be also the three aspects from which the students' ability is assessed.
