Reeves (2002) has offered one set of criteria that teachers might use to distinguish between what is nice and what is essential for students to know:
- Endurance - long term knowledge
- Leverage - applicable to many academic disciplines
- Readiness - prerequisite knowledge for the next level of learning
- Is regularly assessed on provincial exams
Outcomes meet most criteria in order to be essential.
