It's easy for learners to see excellence as quite a narrow thing, instead of seeing excellence in many different forms, depending on what people are doing - excellently. Equally, it's easy for learners (and the people supporting them) to focus strongly on particular ways of measuring excellence, such as public and other exams. In fact, there are many different measures for different kinds of excellence: e.g. audience responses for measuring performing excellence, ingenuity in responding to a challenge as a measure of creativity, assessments and reviews from friends and peers as a measure for many things. Helping learners to understand these 'excellences' and measures, and to take them seriously, is important for helping them to lead their own learning.
