Lexia Efficacy Research Meets the Highest Standards of Evidence as Defined by the Every Student Succeeds Act (ESSA)
April 12 2018 - 9:00AM
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.”
