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.
To gain insight into citizen perspectives on the themes of energy and climate, the Ministry of Economic Affairs and Climate periodically conducts public research. The Public Monitor Climate and Energy 2021 focuses on knowledge, attitude and behaviour of citizens in the field of the climate and energy transition.
BETA partnered with AFSA on two projects to determine how to best communicate about the consequences of bankruptcy.
In the first project, over 6,500 Australians completed one of six educational tools online that explain the consequences of bankruptcy and then assessed their levels of understanding. A pop-quiz and video were most effective, improving people’s understanding by 27 percentage points above the group that saw no educational tool.
In the second project, we introduced five additional…
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…
To promote college access and affordability, education tax credits help with the cost of college by reducing the amount of tax owed. The most generous Federal higher education tax credit, the American opportunity tax credit (AOTC), is a maximum annual credit of $2,500 per eligible student. Yet, many eligible students (or their families) do not claim the credit. Among eligible students, national estimates indicate that 46 percent of independent students and 56 percent of dependent students take…

Higher COVID-19 vaccination rates: did mobile vaccination units result in an increase in the number…
In an effort to boost COVID-19 vaccination rates, mobile vaccination units were rolled out in late 2021. This strategy proved successful: the number of vaccinations administered was between 1.1 and 14.5 times higher in neighbourhoods on the days they were visited by mobile units. The units were more effective in rural areas than in urban settings. In addition, they proved to be more effective than average in neighbourhoods with a higher proportion of SGP voters and still effective, although to a…
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.
BETA Survey Series: Towards Net Zero – BETA will conduct a survey series to fill current information gaps and better understand barriers and enablers to making high impact household decisions that limit greenhouse gas emissions.

Levelling the playing field in police recruitment: Evidence from a field experiment on test…
How to increase diversity in the police is an unanswered question that has received significant political and media attention. One area of intervention is the recruitment process itself. This study reports the results of a randomized controlled trial (RCT) in a police force that was experiencing a disproportionate drop in minority applicants during one particular test. Drawing on insights from the literatures on stereotype threat, belonging uncertainty and values affirmation exercises, we…
The Adult Migrant English Program (AMEP) is a government-funded program for all permanent visa holders and some temporary visa holders who have less than a vocational level of English. Not all people who are eligible for the AMEP participate in it. The Department of Home Affairs commissioned BETA to evaluate the effectiveness of communication in participants’ home languages on increasing participation in the AMEP.
Trial 1: We will send text messages to speakers of Mandarin, Cantonese,…
