Teaching counselling ethics is not only about distributing a list of codes of ethics, but it also plays an important role in the acquisition of competencies. The current study utilised a single-group pre-test and post-test design to evaluate counselling students' multicultural counselling competencies, effective counsellor characteristics, basic psychological needs, and empathy skills as a result of taking a 14-week ethics course designed with a flipped classroom approach. The study group included 59 counselling students. The results showed a significant increase in the post-test scores of students' multicultural counselling competencies, effective counsellor characteristics, basic psychological needs, and cognitive empathy skills. Limitations of the study and implications for future research are discussed.
