Characteristics of study sample as reported by study author.
| Other or unknown | 100% |
The study was set in Texas and included 31,432 ninth-grade public high school students in the 2000–01 school year. Data were drawn from the Texas Education Research Center P-20 longitudinal data system. The study had 10 years of longitudinal follow-up data.
The authors used the following sample characteristics in the propensity score matching procedure: gender, race/ethnicity, socioeconomic status, English language learner, gifted, special education, vocational education, and prior achievement. However, the study does not report descriptive information for the total sample or for the two groups, so the demographic characteristics of the sample are unknown.
The intervention was defined as completion of at least one dual-enrollment course in the state of Texas during the junior or senior year. No specific information about the nature of the dual enrollment courses was provided.
The comparison condition was created from students who attended schools that did not have access to dual-credit courses in the state of Texas during their junior or senior year.
The study does not describe any specific supports for the implementation of dual enrollment programs in the study. In Texas, dual enrollment programs are funded at least partly by the state. In addition, all districts in the state are required to provide dual enrollment opportunities.
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.
An outcome is the knowledge, skills, and attitudes that are attained as a result of an activity. An outcome measures is an instrument, device, or method that provides data on the outcome.
A finding that is included in the effectiveness rating. Excluded findings may include subgroups and subscales.
The sample on which the analysis was conducted.
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.

Study findings for this report.
Based on the direction, magnitude, and statistical significance of the findings within a domain, the WWC characterizes the findings from a study as one of the following: statistically significant positive effects, substantively important positive effects, indeterminate effects, substantively important negative effects, and statistically significant negative effects. For more, please see the WWC Handbook.
The WWC may review studies for multiple purposes, including different reports and re-reviews using updated standards. Each WWC review of this study is listed in the dropdown. Details on any review may be accessed by making a selection from the drop down list.
Tier 1 Strong indicates strong evidence of effectiveness,
Tier 2 Moderate indicates moderate evidence of effectiveness, and
Tier 3 Promising indicates promising evidence of effectiveness,
as defined in the
non-regulatory guidance for ESSA
and the regulations for ED discretionary grants (EDGAR Part 77).
