About Mathematics: A Look at the OGT

Mathematics: A Look at the OGT provides classroom teachers, curriculum specialists, and other leaders in mathematics education with resources and information about using item-specific data from the OGT to change mathematics instruction and model professional discussion. Watch 30 to 40-minute webcasts that elaborate on an engaging and stimulating conversation about how to analyze test items and data from state and national tests to improve instructional practice. And take advantage of the mini-collections—small sets of ORC resources—created to support the articles and webcasts by providing additional examples and materials.
