Clinical experiences remain an integral component of teacher preparation programs. One type of clinical experience is the Comprehensive Scope and Sequence Model, which calls for five hierarchical levels of clinical experiences: (1) college classroom practice activities; (2) campus laboratory practice activities; (3) block practicum field experiences in local schools for one semester; (4) one semester of student teaching; and (5) first year teaching follow-up support services. The model addresses the following criteria for assessing clinical experiences as reflected by the literature: varied settings; a wide array of experiences that are systematically selected, tied to course objectives, and integrated into the total teacher preparation program; careful selection of mentors; sequencing and monitoring of experiences; assessment of student performance; provision for practice of theory; opportunities for reflection on teaching; block practicum experiences; a year of school experience; follow-up support for first year teachers; and support of experiences by technical and material resources. A discussion of each level and of how the model addresses the criteria for effectiveness is provided. (Author/LL)
