Supercharging Literacy: Research Proves Core5 and Lexia English are Better Together

If educators in your district already use Lexia® Core5® Reading to strengthen foundational literacy skills, you’re on the right track. Now pairing Core5 with Lexia English Language Development™ offers a proven path to even greater success for multilingual learners, who need targeted language development in tandem with reading instruction.

A recent study revealed multilingual learners using both programs outperformed those using Core5 alone in measurable ways:

• A 22-point higher average on the Smarter Balanced English Language Arts (SBAC ELA) assessment

• A more than 1.5x higher SBAC ELA proficiency rate (23% vs. 14%)

• Strong performance on the California English Language Proficiency Assessment (ELPAC), which addresses speaking, listening, and grammar

Together, these programs create a comprehensive, equity-driven approach that empowers every multilingual learner to thrive. Core5 builds critical reading skills, while Lexia English supports oral language development, academic vocabulary, and grammar—key components of English proficiency and long-term literacy.

Add Lexia English to your Core5 implementation and ensure your multilingual learners have the tools they need to succeed. If you are ready to unlock even greater potential for your multilingual learners, read on to discover how this partnership can transform their language journey.
