About the Ongoing Assessment Project (OGAP)

The Ongoing Assessment Project (OGAP) is a systematic and intentional formative assessment system in mathematics based upon the mathematics education research on how students learn specific concepts, common errors students make, or pre-conceptions or misconceptions that interfere with students learning new concepts and solving related problems. OGAP presently has formative assessment systems for additive reasoning, multiplicative reasoning, fractions, and proportionality. These mathematical topics represent about 80% of the mathematics in the CCSSM in their respective grade spans. At the foundation of OGAP is teacher knowledge that includes mathematical content, mathematics education research on how students learn mathematics concepts underpinning the OGAP Framework/Learning Progression for each OGAP math topic, and formative assessment practices specific to mathematics.. Therefore, involvement in OGAP involves an investment in extensive professional development and ongoing support.

The system involves using OGAP knowledge and the OGAP Learning Progressions to implement a continuous and intentional system of instruction, probing with instructionally embedded questions, and analysis of evidence in student work to make timely instructional modifications.
