Uncover student thinking with a complete K-8 math assessment system
Expect more ¿ì²¥³ÉÈË your assessments with mCLASS® Math, a complete K–8 benchmark and progress monitoring assessment system that shows how students performed, reveals their math thinking, and provides teachers with recommendations to drive grade-level success.
About the program
mCLASS Math is a digital assessment system designed to evaluate student performance and growth against grade-level expectations throughout the year. The program empowers educators and students with:
- Valid, reliable, and research-based assessments that take less time, so you can measure student proficiency and growth without taking time away ¿ì²¥³ÉÈË instruction.
- Valuable insights into student math thinking that move beyond right or wrong answers, revealing students’ processes so you can accelerate grade-level learning by building on what they already know.
- Data that drives instruction, turning assessment results into clear next steps for differentiation and intervention—all aligned with your core math program and MTSS framework.
mCLASS Math is available for grades K–5 in the 2025–26 school year and for grades K–8 in the 2026–27 school year.
Access deeper insights into students’ understanding
—
Traditional assessments focus only on right or wrong answers. mCLASS Math goes deeper, revealing how students think about grade-level math and what they already understand.
This asset-based approach recognizes that every student has their own ways of thinking. Their individual strengths, experiences, understandings, and strategies—or assets, as we collectively refer to them—inform the robust data that powers mCLASS Math. By focusing on what students already know and where they need support, teachers can confidently build on each target area for growth and accelerate grade-level learning with confidence.
Traditional assessments |
mCLASS Math’s asset-based assessments |
| Focus on student deficits | Highlight what students already know and how they think to build on their strengths |
| Require lengthy assessments with separate questions to address each skill | Efficiently gather multiple data points per item, reducing assessment time |
| Judge answers solely as correct or incorrect | Reveal students’ thinking and understanding behind their answers |
| Provide data disconnected ¿ì²¥³ÉÈË core instruction and intervention | Deliver data-driven recommendations aligned with core instruction and MTSS |
mCLASS Benchmark Assessments
- Digitally administered to the whole class three times a year (BOY, MOY, EOY) to measure growth against grade-level expectations
- Provide real-time visibility into student work and responses
- Diagnostic and screening tools to identify strengths and areas for Tier 2 and Tier 3 interventions
- Flag potential risk of dyscalculia for early support
mCLASS Progress Monitoring
- Quick, targeted assessments administered between benchmarks
- Track student performance in specific skills and concepts over time
- Inform instructional adjustments with in-the-moment recommendations
- Ensure interventions are effective to keep students on track
