Frequently Asked Questions

Lexia’s mission is to help more students learn to read, write, and speak with confidence by equipping educators with evidence-based literacy solutions.

For more than 40 years, Lexia® has focused on closing literacy gaps through research-driven instruction, high-quality professional learning, and technology that supports effective teaching. Lexia partners with schools and districts to build strong literacy systems grounded in the science of reading and designed to support all learners.

Lexia’s solutions combine science of reading-aligned instruction, embedded assessment, and educator support into a cohesive literacy system.

Rather than offering isolated tools, Lexia provides integrated programs that adapt to individual student needs, provide educators with actionable insights, and build educator knowledge alongside student learning. This systems-level approach helps educators implement Structured Literacy with fidelity and sustain results over time.

Lexia supports educators and leaders from pre-K through high school with professional learning that includes tools, training, and insights that make literacy instruction more effective and applicable. Lexia offers personalized professional learning courses for early childhood educators, K-5 educators, K-5 administrators, and upper-elementary through high school educators. Many edtech programs focus primarily on student-facing technology, but Lexia prioritizes teacher development as a critical part of improving literacy outcomes.

Teachers receive actionable data and instructional resources aligned to student needs. Facilitators and administrators gain visibility into progress, usage, and implementation to guide decision-making, professional learning, and systemwide improvement. An array of implementation supports is available for all Lexia products through partnership services, professional learning and events, and content in our Lexia Community Center to help ensure successful implementation.

As of 2025, the Lexia® LETRS® Suite offers sustainable learning solutions through Lexia® LETRS® Connect™ and Lexia® LETRS® Coaching™. LETRS is widely recognized as the gold standard in science of reading professional learning, accredited by the International Dyslexia Association® (IDA) and validated through peer-reviewed research. Large-scale implementations have demonstrated meaningful improvements in teacher knowledge and instructional practice, with states such as Alabama reporting that 91% of third grade students were reading at or above grade level following statewide LETRS adoption. Lexia Aspire® Professional Learning also delivers flexible, self-paced professional learning aligned to the science of reading for upper-elementary through high-school educators. Together, Lexia’s professional learning and student-facing programs strengthen both the human side and the technology side of literacy improvement.

Yes. Lexia is designed to support multilingual students through explicit language development and literacy instruction.

Lexia English Language Development™ builds academic English skills while reinforcing reading, writing, listening, and speaking. Instruction is grounded in research about second-language acquisition and integrates language development with core literacy skills to support multilingual learners across grade levels.

Implementation timelines vary, but educators at many schools begin using Lexia effectively within weeks. 

Lexia partners with schools and districts to support onboarding and rollout based on local goals and capacity. Programs are designed to integrate into existing schedules and instructional models, allowing educators to quickly begin realizing value while building toward long-term sustainable success.

These integrations help streamline rostering, single sign-on, and data management, reducing administrative burden for schools and districts. Integration options vary by system and district configuration.

Yes. Lexia’s programs are grounded in the science of reading and supported by a robust body of research. Lexia solutions are built on decades of cognitive science, literacy research, and classroom evidence. The company publishes peer-reviewed studies and collaborates with independent researchers to evaluate effectiveness across diverse student populations and instructional settings. Lexia’s approach is backed by 20+ peer-reviewed studies, and Lexia products have evidence that meets ESSA Strong and Moderate standards.

Lexia’s literacy solutions are supported by a broad portfolio of independent research and third-party validation. Studies conducted by external organizations, including the RAND Corporation, have found that students using Lexia® Core5® Reading demonstrate greater reading gains than their peers. Independent evaluations at the state level also have recognized Core5’s effectiveness; for example, the Idaho State Board of Education identified Core5 as the most effective K–3 literacy program in its review, outperforming programs such as i-Ready and Amira. Additional independent studies in states including California and Maryland have found measurable student progress aligned with Core5 use.

Beyond Core5, other Lexia programs also have strong external evidence. Lexia® PowerUp Literacy® meets ESSA Strong Evidence criteria and has independent studies showing multiyear growth within a single school year. Lexia English has been evaluated using state language proficiency assessments, and the LETRS professional learning suite is supported by third-party evaluations and peer-reviewed research demonstrating increased educator knowledge and improved classroom practice. Together, this body of independent research provides strong external validation for Lexia’s approach to literacy instruction.

Yes. Lexia’s student-facing programs—Core5, PowerUp, and Lexia English—are built on evidence-based instruction aligned with the science of reading, and their impact has been validated through extensive research. Core5 meets ESSA Strong Evidence criteria and has been shown to support significant student growth, with progress in the program predicting end-of-year test performance. Schools using Core5 have also demonstrated strong correlations with improved state assessment outcomes, including districts in California, Texas, Florida, and Maryland.

Research about other Lexia programs also shows measurable impact. PowerUp has been found to be up to five times more effective than the average middle school intervention, with students demonstrating a 35% improvement in reading skills within one school year. Students using Lexia English also tend to achieve higher scores on English language proficiency assessments. 

These results reflect Lexia’s foundational approach: Technology is designed to support educators, not replace them. By providing real-time, actionable data, Lexia enables teachers to deliver targeted instruction that helps improve student outcomes.

Educators at schools using Lexia programs have demonstrated positive literacy outcomes across grade levels and student groups.

Independent studies and district evaluations show gains in foundational reading skills, comprehension, and language development for students using Core5, PowerUp, and Lexia English. Results vary by context and implementation, but evidence consistently supports Lexia’s effectiveness.

Lexia designs literacy solutions to be accessible, inclusive, and supportive of diverse learners.

Programs include built-in accessibility features, culturally responsive content, and instruction aligned to Structured Literacy principles. By personalizing learning and supporting educators with clear data and guidance, Lexia helps schools provide equitable literacy opportunities for all students.

Lexia provides ongoing implementation support and data tools designed to help schools and districts integrate our products effectively and sustainably.

All customers have access to onboarding resources, best-practice guidance, and the Lexia Customer Community, which offers events, tools, and peer collaboration to support successful adoption.

The myLexia® platform delivers real-time data and actionable insights into student progress, program usage, and instructional needs. This enables educators and leaders to make informed decisions at both the classroom and system levels and supports effective, long-term implementation.

Yes. Independent studies and multiyear analyses show students using Lexia’s adaptive programs demonstrate learning that extends beyond the program environment. Progress in Core5 has been shown to predict end-of-year performance on standardized reading assessments, while students using PowerUp have demonstrated multiple years of growth reflected in improved test scores and measurable acceleration. 

State-level research in California, Maryland, and Idaho has also found gains on real-world assessments following Lexia use. This transfer is supported by Lexia’s instructional model, which provides educators with program-driven insights they can incorporate into classroom instruction to reinforce and extend student learning.

Yes. Lexia is committed to protecting student data and complying with applicable privacy laws and regulations. Lexia follows federal and state requirements, including FERPA and COPPA, and maintains safeguards to protect the confidentiality and security of student information. Core5, PowerUp, and Lexia English have earned iKeepSafe® data privacy certifications, demonstrating alignment with nationally recognized standards for student data protection.

Lexia’s programs are designed with privacy and security in mind, following data-minimization principles that limit data collection to what is necessary for instructional use. Student data is used solely to support instruction and help educators make informed decisions, and Lexia does not sell or share student data. Lexia also supports schools and districts in meeting privacy and security requirements across federal and state data protection frameworks. Data privacy and security remain integral to Lexia’s product design and operations.

Lexia products are primarily designed for use by schools and districts.

Some programs may be available through specific partnerships or distributors, but Lexia focuses on supporting educators through institutional implementation to ensure effective use, professional learning, and instructional alignment.

Lexia is designed to support blended, hybrid, and remote learning models.

Students can access instruction digitally while educators use data and instructional resources to guide in-person or virtual teaching. This flexibility allows schools to adapt Lexia programs to a wide range of instructional settings and schedules.

Lexia supports students with dyslexia and reading difficulties through explicit, Structured Literacy instruction.

Programs target foundational skills such as phonological awareness, phonics, fluency, vocabulary, and comprehension. Instruction adapts to student performance, providing practice and support aligned to research-based approaches for struggling readers.

Lexia supports a “limited, intentional” use model. Our programs:

• Use short, structured sessions backed by research—not open‑ended usage

• Provide nonscreen, teacher‑led lessons supported by detailed instructional resources

• Give teachers the data they need to focus on intervention rather than monitoring

• Emphasize reading, writing, and oral language, not point-based gamification

Lexia’s philosophy is clear: Screens should support high‑quality educator instruction, not replace it. Our professional learning programs (LETRS, Aspire) further reduce reliance on tech by empowering educators with deep instructional knowledge.
