Proven Success for California K–5 Students
- ESSA Level: Level 2
- Program: enVision Mathematics
- Subject: Mathematics
- Grades: K–5
- Study Year: 2025
- Study Completed By: Savvas
Key Findings
A quasi-experimental study of Grades 3–5 found that schools using enVision Mathematics K–5 for a full school year had math proficiency rates that were 3.5 percentage points higher on the mathematics section of the Smarter Balanced Summative Assessment system than similar schools using other elementary math programs, a statistically significant difference.
Study Description
The study examined whether enVision Mathematics K–5 is associated with higher math performance on the mathematics section of the Smarter Balanced Summative Assessment system by comparing schools that use enVision Mathematics with closely matched control schools that use other math programs. The final sample was diverse, including:

Proven Success for California High School Students
- ESSA Level: Level 2
- Programs: enVision A|G|A and enVision Integrated Mathematics
- Subject: Mathematics
- Grades: 9–12
- Study Year: 2023
- Study Completed By: Savvas
Key Findings
A quasi-experimental study found that schools using enVision Mathematics A/G/A and enVision Integrated Mathematics for a full school year had math proficiency rates that were 14.2 percentage points higher on the mathematics section of the Smarter Balanced Summative Assessment system than similar schools using other high school math programs, a statistically significant difference.
Study Description
The study examined if enVision A|G|A and enVision Integrated Mathematics are associated with higher math performance on the mathematics section of the Smarter Balanced Summative Assessment system by comparing schools using enVision A|G|A and enVision Integrated Mathematics to closely matched control schools using other elementary math programs. A total of 31 enVision A|G|A and enVision Integrated Mathematics and 31 control schools in California were represented in the sample at third to fifth grade. The final sample was diverse, including:
