The overt or explicit curriculum in education is designed to meet the inferred needs of students, as they are those identified by teachers or individuals to improve the classroom learning environment. In the ethics of care philosophy, inferred needs are referred to as those that come from those not directly expressing the need. Most needs identified by educators for learners are inferred needs because they are not being identified by the learners themselves. Students' inferred needs can often be identified interactively, through working with them one on one or observing their behaviour in a classroom environment.
