The NBPTS has been the topic of much discourse in the measurement, teacher education, and education policy literature; nearly 200 articles discuss the board’s work. However, the majority of these documents do not report on empirical research, and only a handful yield valid findings related to the questions in our charge. Thus, we relied on an evidence base that was neither broad nor deep, which we supplemented with additional investigations.
DEVELOPMENT OF THE STANDARDS AND ASSESSMENTS
Over a seven-year period, the board worked to identify the essential characteristics of accomplished teaching and to develop a method for identifying teachers who demonstrated these practices. Their product is a set of standards for 25 teaching specialty areas. The standards in each area describe the ways accomplished teachers demonstrate that they know their students, their subject matter, and how to teach it; think systematically about their practice; and learn from their experience. Assessments for each specialty were designed to allow teachers to demonstrate their proficiency in classroom settings. To earn NBPTS certification, teachers must respond to six computer-based constructed-response exercises that measure subject
