Proven Results: How Lexia Core5 Reading Is Moving the Needle in California Schools

See the data behind the difference at a glance.

As an LAUSD school leader, you’re constantly weighing what’s worth your teachers’ time, your students’ minutes, and your site’s resources. You’re being asked to align with AB 1454, the Golden State Literacy Plan, and LAUSD’s own literacy priorities while also showing measurable progress on SBAC, ELPAC, and your school’s growth goals. When a literacy resource lands on your desk, the first question is almost always the same: Does this actually work for students like ours?

This one-page infographic answers that question—fast.

It distills a large-scale Lexia® research study of more than 1 million California students across nearly 5,000 elementary schools into a clear, shareable snapshot you can take into your next ILT meeting, leadership team huddle, or conversation with your local district office. 

Inside, you’ll see:

• How California third through fifth grade students using Lexia® Core5® Reading with fidelity scored 2–3 points higher on the Smarter Balanced ELA assessment—even after controlling for prior achievement and demographics

• How Core5 schools outperformed peers on the Smarter Balanced Math assessment 

• The research question, sample criteria, and data points behind the findings 

For LAUSD schools serving large multilingual learner populations and students with diverse learning needs, the infographic’s takeaway is especially meaningful: when Core5 is implemented well, California students grow measurably and across content areas.
