ESSA Effectiveness

1. Publication date

Due to the rapid improvements often made to digital learning solutions, studies completed more than 10 years ago may not accurately or appropriately reflect the effectiveness of currently available programs.

2. Sample size

Studies that include more students, schools, and school districts are more capable of detecting the true effect of the program on student outcomes and the observed results are more likely to be replicable in different student populations.

3. Statistically significant positive effects

Positive research results that are statistically significant demonstrate that the observed outcomes can be confidently attributed to the evaluated program and not due to some other factor(s).

4. Attrition

Many categorically similar study participants or groups may prematurely exit a study for a variety of reasons. When this occurs, research rigor may be compromised.
