Practicum, Preceptorship Field Placement. Practicum, Preceptorship Field Placement is where student learning takes place off campus with the permission of an external agency. In some cases, student supervision and input to evaluation is by the staff of the external agency. This would normally be the case in practica for Nursing, Early Childhood Education, Social Service Worker, and Special Needs. In these cases, the student may also require varying levels of observation by College Faculty. The number of students in one section of a given practicum will be determined by the Xxxx in consultation with the School Chair/Department Head.
