Foundational Learning Is Declining Before It Is Even Built

Across the United States, foundational learning gaps in reading and math have widened post-pandemic and still haven’t fully recovered. Based on benchmarks from the National Assessment of Educational Progress, roughly 30–40% of K–12 students are performing below grade level, affecting an estimated 20–25 million children. In California, state data continues to show persistent gaps in literacy and math proficiency across districts, particularly in the Central Valley and parts of Southern California. You can see what this looks like in districts like Los Angeles Unified School District, Fresno Unified School District, and Oakland Unified School District. Students are moving forward each year, but many are doing so without a solid grasp of the basics. Progression is continuing. Mastery is not.

In Los Angeles Unified School District, the gap shows up clearly inside the classroom, as reflected in district-level reporting. In the same third-grade class, you might have a few students still working through basic decoding, while others are expected to analyze and interpret text. The lesson moves forward for everyone, but not everyone is actually keeping up with it. Over time, that spread only gets wider, and it becomes harder for both students and teachers to bridge it.

In Fresno Unified School District, the challenge is shaped by real constraints. Schools serving low-income communities continue to report lower proficiency rates, as highlighted by the Public Policy Institute of California. Teachers are often working with large class sizes and limited time for individual support. So even when a student hasn’t fully built reading fluency or number sense, they’re still expected to move on. The work gets done, assignments get turned in, but the understanding underneath isn’t always there.

In Oakland Unified School District, there have been real efforts to close these gaps, but the results are uneven. Some students benefit from targeted programs, while others miss out due to inconsistent access or attendance. Early literacy gaps, especially for underserved students, are still not fully closing. From the outside, things can look like they’re improving. But inside the system, the depth of learning often tells a different story.

Addressing this doesn’t start with a big overhaul. It starts with smaller, more consistent shifts. Giving students time to actually work through a concept until it clicks. Letting teachers slow down where needed instead of feeling pressure to cover everything. Making sure parents have visibility into what “foundational” really means—whether that’s reading fluency, basic math reasoning, or just the ability to think through a problem. These aren’t dramatic changes, but they add up. The goal isn’t to move students forward faster. It’s to make sure that when they do move forward, they’re ready.

The question is not just what is broken, but what we choose to do differently from here.
