Effective ongoing assessment, referred to in the education literature as formative assessment or progress monitoring, is indispensable in promoting teacher and student success. Feedback through formative assessment is ranked at or near the top of practices known to significantly raise student achievement. For decades, formative assessment has been found to be effective in clinical settings and, more important, in typical classroom settings. Formative assessment produces substantial results at a cost significantly below that of other popular school reform initiatives such as smaller class size, charter schools, accountability, and school vouchers. It also serves as a practical diagnostic tool available to all teachers. A core component of formal and informal assessment procedures, formative assessment allows teachers to quickly determine if individual students are progressing at acceptable rates and provides insight into where and how to modify and adapt lessons, with the goal of making sure that students do not fall behind.
