Experts have highlighted research for many years that stresses how the most important part of education success relates to the quality of the teaching in the classroom. RAND reports that “When it comes to student performance on reading and math tests, teachers are estimated to have two to three times the effect of any other school factor, including services, facilities, and even leadership.” Quality teaching matters as much in early childhood education as it does in K-12 classrooms. In fact, the effort to better understand and support early childhood educators is growing.
