While teachers continue to learn and grow as they gain experience, the foundation for their skills is provided by their initial teacher education program. And of all the parts of teacher education, none is more important than clinical practice. In general, the field of education has long recognized and championed the importance of practice. A 2010 blue ribbon panel organized by the profession's accrediting body called on the field of education to see clinical experiences as the core of teacher preparation. The two standards addressed in this brief take different, but complementary approaches to better understanding the quality of clinical practice: the Clinical Practice standard addresses three elements of clinical practice that have an outsized effect on its overall value, while the Classroom Management standard takes a closer look at how teacher candidates practice a key instructional skill. For each standard, the brief provides key findings from the 2020 "Teacher Prep Review" (TPR) and a list of exemplary certification programs that earned an "A" in 2020. Three recommendations for educator preparation programs conclude the brief. [A list of "Teacher Prep Review" sponsors can be found on page 28 of the PDF.]
