A landmark study completed by Project Tomorrow, the internationally recognized education nonprofit organization, found that students whose teachers used Vocabulary.com in the classroom had significantly higher achievement scores and experienced substantially more growth on state standardized ELA tests than students whose teachers did not use the platform.
Researchers examined achievement score data from four middle schools in Broward County Public Schools, one of the nation's largest school districts. The research established these key findings:
- Across grades 7 and 8, students whose teachers used Vocabulary.com with fidelity showed almost double the year-over-year increase in ELA test scores as compared to those who did not use the platform.
- Additionally, students whose teachers regularly used Vocubulary.com achieved higher mean scaled FSA ELA test scores than their peers who did not regularly use the platform.
- This pattern was consistent when the student data was disaggregated for African-American and Hispanic/Latinx students.
