A system of evaluation should be an essential part in the planning of each phase of curriculum development. The evaluation of the curriculum impact on the students can only be measured by comparing the students' status just before beginning the curriculum with their status at the conclusion of their studies. If little or no change in status is found, several possibilities may be considered. The college objectives may be unclear, inappropriate, or unachievable; student experiences may not be relevant to the objectives; the organization of the curricular experience may be inadequate; and/or the evaluation instruments may be invalid.
