The NYC Behavioral Design Team provided an additional reminder to Supplemental Nutrition Assistance Program (SNAP) clients that they would lose their benefits if they did not complete the SNAP recertification process. Highlighting the consequences and including attention-grabbing icons made this NYC BDT supplemental SNAP recertification notice more salient and actionable for clients.
PROJECT SUMMARY
Students were sent two redesigned emails during the course selection process: a pre-registration email that laid out instructions and procedures for registration, and a post-registration email that notified students if any of their upcoming courses did not fit financial aid requirements.
IMPACT
The average aid award for students receiving both redesigned emails rose by $150.28 per student for the Spring semester compared with students who received neither email, with a total…
While potential voters may register and intend to vote, many registered voters ultimately do not participate in elections. In addition, previous studies have not addressed how the impact of the text messages may vary among causal voters compared to habitual voters. Casual voters are defined as those who had previously only voted in the presidential election or major elections. Habitual voters are defined as those who have a higher propensity to vote (in this case, those who voted in each of the…
Challenge
Students in low-income districts are less likely to sign up to take the Gifted and Talented (G&T) admissions test than their peers in higher-income districts. As a result, fewer students from low-income districts test into and attend G&T programs that could improve educational outcomes and provide meaningful opportunities. To the extent that the city may use sign-up rates as an indicator of demand, and thus where additional G&T programs should be located, low sign-up rates can mean…
Challenge
Research suggests that some students—including low-income, underrepresented minority, and first generation students—avoid applying for financial aid due to a combination of psychological reasons. Some are overwhelmed by the complexity of the process, while others worry they’ll feel out of place in college or be stigmatized for their socio-economic background. These psychological factors can cause students to avoid applying for aid, or fail to complete their financial aid…
PROJECT SUMMARY
Arizona State University freshmen students eligible for the Student Engagement and Employment Development Plan (SEED), a work-study program, received emails designed to emphasize the benefits of joining the program and eliminate hassles in the application process.

Challenge
Many eligible college students fail to apply for financial aid offered by the federal government altogether. Of those who do apply, many more reduce their chances of receiving aid by failing to apply by the priority deadline. In the 2013-2014 school year, more than 80% of students at Arizona State University who filed their financial aid applications did so after the priority deadline had passed, which can result in a lower aid package. This project’s goal was to increase the number…
In the spring of 2021, as COVID-19 vaccines became accessible to the US's general public, ideas42 and the Boston Transportation Department launched the FreeRide pilot program to encourage commuters to use transit (subway and bus) and bike share as they commute to work. The FreeRide program was designed to accomplish three main goals:
• Support small businesses and employees who have endured economic hardship during the pandemic.
• Shift employees away from single-occupancy vehicle use,…
Installation of large, moveable trash containers and trash cans in convenient locations made disposal of large trash bags and litter easier for residents of New York City public housing. A package of indoor and outdoor posters informed people of the new policy and encouraged them to use the new infrastructure.
PROJECT SUMMARY
Teachers in a summer school program for high school students provided brief, individualized, messages for parents with information about their child’s performance and behavior in school on a weekly basis.
IMPACT
Providing parents with individualized messages increased the probability a student earned credit for each class by 6.5 percentage points – a 41% reduction in failure rates.
