Review Protocols
This review focuses on mathematics interventions that are typically used in grades 9–12 and are designed to affect students’ mathematics achievement. Whether an intervention falls under the scope of this review depends on both the grade level and content of the intervention. For example, the review can include students in lower grades (such as grades 7 and 8) if they use a secondary mathematics intervention such as algebra or geometry.
The following research questions guide this review:
- Which interventions are effective at increasing the learning of secondary mathematics content (e.g., algebra, geometry, trigonometry, and calculus) and skills?
- Are some secondary mathematics interventions more effective for certain types of students, particularly students who are at risk of failure in mathematics?

What is a Protocol?
Starting in January 2021, the What Works Clearinghouse (WWC) uses the Study Review Protocol in combination with the Procedures and Standards Handbook to guide reviews of all studies. In particular, the Study Review Protocol provides additional information on eligible outcome domains for all topic areas reviewed by the WWC and provides examples of outcome measures that fall within each domain.
When conducting systematic reviews, the WWC uses the Study Review Protocol to review studies and an accompanying topic area synthesis protocol to define the parameters of the systematic review. The synthesis protocol provides criteria for the literature search; guidance on how to identify and prioritize relevant studies for review and inclusion in evidence synthesis products; and guidance on intervention, sample, and outcome eligibility criteria for the synthesis.
Prior to 2021, studies were typically reviewed using a topic-specific synthesis protocol and the corresponding version of the Procedures and Standards Handbook. In addition to defining the parameters for the review, these protocols described any topic-specific applications of the design standards, such as how to establish baseline equivalence between samples when required.
