National Board Certification is recognized as the gold standard in teacher certification and is the highest teaching certificate a teacher may achieve. National Board Certification requires a teacher to analyze and reflect on a range of instructional practices and the positive impact their practice has on student learning. To achieve certification, teachers must complete four components and submit sufficient evidence of their content knowledge, differentiation of instruction, classroom environment, assessment literacy and professional learning and collaboration. Salt Lake City School District has the largest number of National Board Certified Teachers of any district in Utah.
