Technology-Based, Personalized Literacy Program to Accelerate Development of Pre-K-5 Reading Skills

App of the Week

Developed by Lexia Learning, a Rosetta Stone company, Lexia® Core5® Reading is a research-proven, technology-based literacy program that accelerates the development of fundamental through advanced literacy skills for students of all abilities in grades pre-K–5. Core5 helps students as they learn to read and later when they begin to read to learn, supporting them in preparation for college and career ready standards.

In Core5, students work independently on engaging activities that help enrich and improve their literacy skills. Built to meet rigorous content standards, the program is designed according to the latest education research, with dynamic and engaging content to motivate students and support self-directed learning.

The program offers true personalization to ensure each student receives the right level of instruction on different skills to achieve literacy success. Advanced students have the opportunity to accelerate beyond their grade-level skills, while struggling students are scaffolded with simplified assessment formats and explicit instruction.

Lexia Core5 is not only research-based, but also has research-proven results. Core5 is research-proven to improve reading achievement, validated by 18 externally reviewed research studies that meet the standards of evidence under the Every Student Succeeds Act (ESSA).


Formats/platforms are used:

Core5 is web-based and can be used on any computer, laptop, or Chromebook and the Lexia Core5 app is available for iPad. Additionally, teachers can monitor class data through or with the myLexia app for any iOS device and Apple Watch.

Lexia is actively working to update the Core5 Android app so that it supports the Expanded 21-level version of Core5. At present, we do not have a firm release date we can share, but it is our goal to make the updated app available sometime in the 2020-2021 school year. We will communicate the release date as soon as it is finalized.

Problem solved:

Core5 helps substantially reduce students’ risk for reading failure by utilizing personalized instruction to bring struggling students up to grade level standards while still being able to give accelerated and on-track students the instruction they need to thrive. Core5 provides explicit, systematic instruction through personalized learning paths and seamlessly adapts based on student performance, targeting skill gaps as they emerge and equipping teachers with the data and instructional resources, they need to personalize instruction for every student. Embedded assessment technology predicts students’ year-end performance and provides ongoing norm-referenced and actionable data to help teachers prioritize and plan instruction with the offline instructional materials.

In a recent end-of-year gains analysis conducted by Lexia Learning, the report looked at almost 900,000 K–5 students using Core5 with fidelity across the United States and found that students of all abilities made substantial progress in the program:

  • Over half of students (53%) who started Core5 working on skills two or more grades below their grade level substantially reduced their risk of reading failure, ending the school year working on skills in their grade level or above in Core5. Among these students, 63% gained two or more grade levels of skills in one year.
  • More than half of students (52%) who started Core5 working on skills one grade below their grade level closed the reading gap and reached their end-of-year, grade-level benchmark in Core5.
  • The vast majority of students (86%) who started Core5 working on skills in their grade level reached their end-of-year, grade-level benchmark or advanced to complete the next grade’s end-of-year benchmark in Core5.



Age or grade range:

Core5 accelerates the development of literacy skills for students in grades pre-K-5.


Support mechanisms:

Core5 is able to identify struggling students through proprietary embedded assessment technology and supports their needs with personalized instruction. If a student struggles in a particular Core5 activity, the program provides a level of scaffolding, removing some of the answer choices and stimuli on the screen. Once the student demonstrates that they understand the skill, they have the opportunity to try the activity again. If the student continues to struggle, the Core5 program provides explicit instruction on the skill and allows the student to demonstrate proficiency before returning to the original activity. As part of Core5’s blended learning model, a targeted, teacher-delivered Lexia Lesson® on the specific skill or sub-skill is automatically prescribed for the student and linked at the point of use in Core5’s educator reports. Lexia Lessons are scripted, explicit lesson plans that follow the gradual release of responsibility model, empowering a teacher or paraprofessional to efficiently and effectively address the student’s specific skill gap.

Lexia Implementation Support Packages help educators implement Core5 with fidelity while sharing instructional best practices. The packages include modules for teachers on data coaching and use of Core5’s targeted instructional materials, as well as support for instructional leaders with goal-setting, success metrics and analysis.


Subject, topic and/or standards:

Lexia Core5 Reading supports educators in providing differentiated literacy instruction for students of all abilities by targeting the six areas of reading instruction through explicit, systematic, and personalized learning. The scope of the program covers phonological awareness, phonics, structural analysis, automaticity and fluency, vocabulary, and comprehension.


Lesson time needed:

Lexia® Core5® Reading has flexible implementation options. The program can be implemented as an instructional supplement to the core literacy curriculum (Tier 1) or as targeted instruction or intensive intervention (Tier 2 and Tier 3).

Based on their risk level and grade, students are given individual usage targets (15-80 minutes per week) for the online component of the program. The time needed for Lexia offline instructional materials, including teacher-led lessons and paper-based practice materials, is variable depending on students’ individual needs. These offline materials can be implemented as part of classroom center rotations, during intervention blocks, or assigned as homework.


Pricing model(s):

Licensing follows an annual subscription model. Options include per-student or unlimited school-wide with bundled implementation support packages.


Additional services included:

With data-driven instruction, student performance data is collected in real-time through Lexia’s embedded assessment technology, Assessment Without Testing. This assessment feature provides actionable, norm-referenced and criterion-referenced performance data without administering a test. The data is correlated to and highly predictive of outcomes on DIBELS, AIMSweb, MAP, and other commonly used assessments.

Additionally, myLexia data reports provide educators with a Performance Predictor that informs them of each student’s chance of reaching end-of-year benchmarks. With this data, myLexia also prescribes the amount of instructional intensity required to improve any student’s likelihood of reaching their end-of-year, grade-level targets.


What makes Lexia Core5?

Lexia Core5 Reading is unparalleled in its ability to support students in their literacy success. Between embedded assessment and progress monitoring, Core5 allows educators to make data-driven decisions about student instruction, ensuring all students receive the attention they need.

For upper elementary students, Core5 is more than a basic literacy program, helping students build academic language skills, word-learning strategies, disciplinary knowledge, comprehension skills, and higher-order thinking.



In Lexia's 3-step personalized learning model students are motivated by their own success and have their own personalized learning paths, student performance data is easy to access and simple to interpret, and teachers have the resources they need for face-to-face instruction and independent student practice.

Lexia products are centered on a personalized approach to learning that gives students more control over the time, place, path, and pace of their learning.  To some, the term "personalized learning" is simply the incorporation of technology to give students more control over their educational experience. Technology can be a key component of a personalized learning approach, but it cannot stand alone. 

Lexia believes personalized learning is a combination of effective, teacher-led instruction combined with an interactive, user-centric experience that supports the varying cognitive abilities of all students. With Lexia, teachers can see detailed, real-time reports that help prioritize and differentiate instruction, allowing students to develop critical reading skills at their own pace.


Here's what users are saying:

“I highly recommend Lexia Core5 Reading. The activities are adaptive, relevant, and engaging for the students and align with our core curriculum. The teachers love that the easy-to-use educator dashboard helps drive their small-group instruction with targeted, offline lessons as part of a blended learning model. Lexia’s Implementation Support Team helps me quickly review and share our data at the district, school and classroom levels to help us refine instruction. Lexia is a company that is not just selling software; but providing the hands-on support our students and our schools need to succeed.”

—Robin Coleman, Curriculum Coordinator, Kane County School District, Utah


“As a teacher, what I appreciate most about Lexia ReadingCore5® is that students can work independently on the program and monitor their own progress. Because Core5 adapts to each student's skill level, students can progress at the pace that’s right for them. In areas where students struggle, Core5 scaffolds down and provides explicit instruction. If a student continues to struggle, the program alerts me and even provides a prepared and targeted lesson for small group instruction. Additionally, Core5 provides pencil and paper practice activities to help students reinforce their new skills. With Core5’s progress monitoring data, the children are able to monitor their own success and I can easily see who needs additional support and for what specific skills. When students complete levels in Core5, we celebrate their accomplishments together.”

—Amy Kuchynsky, Teacher, PS 098, The Douglaston School, New York City


“Core5 enables our teachers to provide differentiated instruction without a lot of additional effort on their part. The program exposes skill gaps in individual students and provides our teachers with Lexia Lessons to address those gaps. This saves them hours of preparation time and lets them focus on the individual needs of their students.”

—Tammy Starnes, Principal, Prattville Primary School, Alabama
