Characteristics of study sample as reported by study author.
This study takes place in elementary schools in New Mexico, United States.
Sample characteristics are not provided in this study.
The SmartStart K-3 Plus program offers 25 additional school days for students to improve achievement and minimize summer learning loss. The schools were randomly assigned to receive either the 25 days of summer services plus regular year services (intervention) or to receive regular school services only (comparison). Meals and transportation were also provided. Instruction was centered on literacy and numeracy and was delivered by certified teachers who had completed professional development in literacy. There was also a parent involvement component, though this aspect varied by district.
The comparison condition consisted of students not engaging in the intervention (business as usual).
There is no support for implementation information mentioned in the report.
An indicator of the effect of the intervention, the improvement index can be interpreted as the expected change in percentile rank for an average comparison group student if that student had received the intervention.
For more, please see the WWC Glossary entry for improvement index.

The group to which the intervention group is compared, which may include a different intervention, business as usual, or no services.
The timing of the post-intervention outcome measure.
The number of students included in the analysis.
The mean score of students in the intervention group.
The mean score of students in the comparison group.
The WWC considers a finding to be statistically significant if the likelihood that the finding is due to chance alone, rather than a real difference, is less than five percent.
