A Crossroads for Math Access in Elementary and Middle School
For California’s K–8 students, the stakes in the 2025 adoption could not be higher. More than a decade after the last adoption, most classrooms are still using programs published in 2018 or earlier — with many students, especially in low-income, rural, and non-white districts, learning from materials that date back to the 2014 adoption.
This joint view of elementary and middle school math curriculum access highlights where outdated materials remain the norm, where progress is being made, and how leaders can use the upcoming adoption to close equity gaps and strengthen coherence.
Together, these reports point to the urgency of the moment — and the opportunity to provide students with the high-quality instruction they need to succeed.
Key Learnings:
- Most K–8 students still rely on outdated programs. The majority of elementary and middle school classrooms are using materials published years ago, underscoring the urgency of the 2025 adoption.
- Equity gaps remain a defining challenge. Students in low-income, rural, and non-white districts — and many multilingual learners, particularly in middle grades — are less likely to access updated, high-quality curricula.
- The 2025 adoption is a chance to reset. District leaders have an opportunity to strengthen access, coherence, and equity across the full K–8 continuum.
