Students Using Lexia Reading Core5 Make Dramatic Reading Gains of Two or More Grade Levels During 2013–2014 School Year
National Usage and Gains Analysis Shows Substantial Progress for Both High-risk and On-target Students When Using the Program with Fidelity

BOSTON (December 2, 2014)—Consider this statistic: Students who can’t read on grade level by third grade are four times less likely to graduate by age 19 than their peers who read proficiently by that time.[i]  Research shows, however, that poor early literacy skills do not necessarily seal a child’s fate; intensive intervention can help close the gap. ii

Helping to close that gap is Lexia Learning, a Rosetta Stone® (NYSE:RST) company, which just released a national Usage and Gains Analysis showing that students in grades 1–5 who used the Lexia Reading® Core5® program with fidelity made significant gains in reading skills. Specifically, the statistical analysis shows that 75 percent of high-risk students who began the 2013–2014 year working on reading skills at least two grade levels behind gained two or more grade levels of reading skills in Core5 by the end of the school year.

“I am struck not only by the research outcomes, but by the efficacy levels of Lexia’s products,” said Michael Horn, co-founder and executive director of the Clayton Christensen Institute. Horn was the keynote speaker at a recent Administrator Summit hosted by Lexia Learning, where he discussed trends in blended learning and other themes from his award-winning book, Disrupting Class. “You will not find a company more dedicated than Lexia to conducting rigorous research in order to support educators in their mission to help students learn to read,” continued Horn.

Further evaluation of the results shows that 32 percent of the high-risk students gained three grade levels of reading skills during the school year, while an additional 43 percent reduced or closed their achievement gap by advancing two grade levels. Students who began the year on grade-level also made remarkable gains: 33 percent accelerated their reading skill acquisition by more than two grade levels, having completed their current grade-level and the entire next grade-level of skills.

“High-risk students face a particularly daunting task, as they need to learn at a rate that is sometimes twice as fast as their peers in order to close the gap,” said Lexia President Nick Gaehde. “It is gratifying to know that our recent analysis validates the Lexia Reading Core5 program’s ability to help high-risk students make dramatic, rapid gains, while also enabling on-target students to continue to soar to even higher levels of reading achievement.”

Over the last year alone, more than one million students in thousands of schools across the country have used Lexia Reading Core5 to improve their reading skills. One educator who has seen the program’s effects first-hand is Heather Vincent, principal at Franklin Elementary in Wichita, Kansas. Vincent’s school uses Core5 as part of the Kansas Reading Initiative, an ongoing statewide grant program that provides schools access to the program to help close reading gaps.

“Lexia Reading Core5 is driving real learning and growth as it closes skill gaps at an exceptional rate,” Vincent said. “It affords students the time to practice and learn, and addresses their deficiencies with precise instructional material. In addition, the program directs the reading intervention specialist via specific action plans and structured lessons so that improvement happens much more quickly than it would without such an effective tool.”

Built on 30 years of educational research, Lexia Reading Core5 is a technology-based reading program for students of all abilities from pre-kindergarten through grade five. Designed to accelerate fundamental literacy skills development, the program provides a personalized learning path for each student with scaffolding and explicit instruction that supports students if they struggle. Each of the 18 levels of age-appropriate, skill-specific activities aligns to the most rigorous state standards, including the Common Core State Standards. The program simplifies differentiated instruction, enabling at-risk students to close the reading gap more quickly while allowing on-level and advanced students to continue to progress.

Lexia Reading Core5 also includes the company’s proprietary Assessment Without Testing® technology. This highly regarded embedded assessment technology gathers student performance data without administering a test, using norm- and criterion-referenced measurements that are highly correlated to, and highly predictive of, student outcomes on commonly used measures such as DIBELS® and aimsweb®.
