Teachers need comprehensive support to improve students' literacy. This Policy Update shares how state boards of education can provide this holistic support to improve through: (1) better teacher preparation standards in early literacy; (2) professional development guidance; (3) high-quality literacy coaches and other support professionals; and (4) a one-stop-shop strategy that aids teachers in aligning curriculum, instruction, and their professional development with the science of reading. Boards can advocate for funding for early childhood educators to receive this support as well.
