Schools continue to face specific and persistent teacher shortages in certain subjects, such as upper-level math and special education, and in certain schools, including historically under-resourced schools and rural schools. The current teacher workforce also has a shortage of teachers of color, who have a positive impact on student outcomes and school climate. These shortages are more likely to impact schools that serve students in rural and urban areas, linguistically diverse students, students identified for special education and students of color. Shortages contribute to students being taught by inexperienced or out-of-field teachers and they can be financially costly for schools and districts. Declining participation in teacher preparation programs, coupled with high turnover in the profession, suggests that a comprehensive approach that accounts for each stage of the teacher pipeline is necessary to recruit and retain effective teachers.
