In June 2015, the WWC restructured our reviews of research on math interventions into two areas instead of three. These two review areas are Primary Mathematics (which includes interventions in which math is presented through multi-topic materials and curricula, typically used in grades K–8), and Secondary Mathematics (which includes interventions that are organized by math content area (e.g., Algebra, Geometry, and Calculus), typically taught in grades 9–12). These two areas replace the prior Elementary School Math, Middle School Math, and High School Math areas, which were organized by student grade level. The Primary Mathematics review protocol and the Secondary Mathematics review protocol provide detailed information about the reviews for each review area. For more information about this change, please download our frequently asked questions.
