BellXcel is committed to continuously strengthening our evidence base through strong and rigorous data collection, research, and evaluation. BellXcel's public and private funding model has received support from national funders such as The Edna McConnell Clark Foundation, The Wallace Foundation, and Ballmer Group. The following studies highlight our measurable impact.
Urban Institute's Independent Evaluation
Researchers from the Urban Institute completed a two-year, randomized control trial of Bell Summer (now BellXcel Summer) to study its impact on children’s reading achievement and parental involvement.
Statistically significant positive impact on reading achievement, particularly for students who fully participated in the program
- Statistically significant positive impact on parents encouraging their children to read and their frequency of reading to them at home
- Parents in the treatment group reported a 50 percent increase in the hours per week they engage in reading and other academic activities at home compared to the control group
- Scholars spent fewer hours watching TV and playing computer games
MCPS' Independent Evaluation
Montgomery County Public Schools' (MCPS) Office of Shared Accountability conducted an independent evaluation of BELL Summer’s (now BellXcel Summer) impact throughout the year using multiple regression analyses that included enrolled and non-enrolled students and controlled for students’ characteristics, including their initial abilities.
Statistically significant evidence of positive impact on MAP scores in math in Grades 3 and 4, and among all students and four subgroups: Hispanic/Latino, English for Speakers of Other Languages (ESOL) recipients, Free and Reduced-price Meals System (FARMS) recipients, and special education students
Statistically significant evidence of positive impact on MAP scores in reading for Grade 3 among all students and among three subgroups: Hispanic/Latino, ESOL recipients, and FARMS recipients
High marks for program administration and for providing timely and useful support throughout the summer
PD made staff better educators and was recognized as a very valuable aspect of the program
Summer as an Accelerator for Teacher Professional Growth
