To help ensure that accomplished teachers reach the students who need them the most, California should incentivize National Board Certified Teachers to teach in high-needs schools, says a report that lays out the strategy for its recommendation. National Board Certification is a voluntary credential offered by the National Board for Professional Teaching Standards. It signifies teachers are instructional experts after completing a lengthy process that includes videotaping instruction, submitting student work samples, and providing analyses of the strengths and weaknesses of their teaching.
