Many educators believe that, regardless of innate abilities and acquired skills, students at different educational levels do not think in the same way. To account for these differences, 119 female students representing four educational levels (high school seniors to graduate students) completed the Watson-Glaser Critical Thinking Appraisal Form A and the Reflective Judgement Interview (RJI). The results supported previous reflective judgement studies in which RJI scores increased with educational level. This finding suggests that the development of reflective judgement is separate from and involves something other than the acquisition of thinking skills, although attainment of critical thinking skills is still necessary for the development of reflective judgement levels.
