The master of arts in education and human development in the field of assessment, testing, and measurement (ATM) in education degree program is designed for individuals who are entering or advancing in positions associated with assessment, testing, and measurement in diverse settings. This specialized field combines the study of human behavior with statistical analysis, testing theory, educational measurement, and evaluation. ATM is the science of measuring educational factors such as learning, preference, aptitude, and personality. ATM specialists (commonly called psychometricians) design tests that collect empirical data and quantify the personal characteristics of individuals, comparing those results within or across populations. In addition to creating assessment instruments, some psychometricians govern the tests and analyze the results.
