Ordering adjectives
At my school the students will get report cards next week. For their effort in a subject they are assigned A to F. To explain what A to F stands for adjectives like ‘average’, ‘excellent’, ‘good’, ‘improvement needed’, ‘less than satisfactory’, and ’satisfactory’ are used.
My problem is that I don’t know if ‘good’ is better than ‘satisfactory’. So the question is, can these adjectives be ordered?
