 Early research on the CBM quickly moved from monitoring student progress to its use in screening, normative decision-making, and finally benchmarking.Indeed, with the implementation of the No Child Left Behind Act in 2001, and its focus on large-scale testing and accountability, CBM has become increasingly important as a form of standardized measurement that is highly related to and relevant for understanding student's progress toward and achievement of state standards.Probably the key feature of CBM is its accessibility for classroom application and implementation.
