Multiple published studies demonstrate strong evidence of program effectiveness and highlight Lexia’s unparalleled depth and breadth of efficacy research

BOSTON (April 12, 2018) – As educators across the country strive to align their instructional plans with the requirements of the Every Student Succeeds Act (ESSA), Lexia Learning, a Rosetta Stone Inc. (NYSE: RST) Company, stands apart with an unmatched depth and strength of evidence of program effectiveness.

ESSA requires Title I schools to utilize evidence-based instructional programs that have demonstrated positive effects on student learning outcomes. This focus on efficacy has established a more rigorous standard for proving what’s working in classrooms and helps schools, districts, and states to shape the future of teaching and learning. Lexia, with a 30-year history of efficacy research, has multiple studies demonstrating the strongest level of evidence according to ESSA legislation.

ESSA legislation categorizes evidence into three different levels: Strong, Moderate and Promising. Lexia has eight studies with Strong evidence—the highest level of rigor defined by ESSA—and an additional seven studies with Moderate or Promising evidence.

· Strong evidence is defined as well-designed, well-implemented experimental studies that include randomly assigned treatment and control groups to eliminate selection biases. This is the highest level of evidence as defined by ESSA, and Lexia has eight studies in this category.

· Moderate evidence is defined as well-designed, well-implemented quasi-experimental studies with treatment and control groups that may not be randomly assigned. There may be some selection biases that are statistically addressed. Lexia has three studies with Moderate evidence.

· Promising studies include correlational evidence that the program has an impact. These studies may not include a control group, but selection effects are addressed statistically. This is the lowest level of evidence as defined by ESSA, and Lexia has four studies in this category.

“The requirements of ESSA underscore the approach Lexia has taken for more than three decades,” said Lexia President Nick Gaehde. “Educators should have confidence that the instructional resources they choose will deliver a statistically significant impact on student outcomes; and Lexia’s 15 efficacy studies not only satisfy the requirements under ESSA, but provide scientific evidence of our programs’ effectiveness.”
