Arnold Ventures

Arnold Ventures (AV) is a philanthropy dedicated to improving the lives of Americans through evidence-based policy solutions that maximize opportunity and minimize injustice. We focus on improving systems where outcomes are falling short, incentives are misaligned, and the time is right for change. To advance this mission, we invest in rigorous research to strengthen the evidence base on what works to improve outcomes for individuals, families, and communities, and to inform policy and practice at scale.

Causal Research to Improve Outcomes for Part-Time Students

Purpose of the RFP

This RFP seeks to fund rigorous causal research that builds the evidence base on effective programs and policies for part-time students and identifies scalable, cost-effective approaches to improve completion and labor market outcomes. Findings should generate actionable insights to inform institutional practice, system-level decision making, and state policy, with the goal of improving outcomes and maximizing return on investment for students and taxpayers.

Population of Interest

Because enrollment intensity is fluid, proposals do not need to limit eligibility to students who are enrolled part-time at baseline. Instead, studies should focus on interventions that primarily serve or are expected to meaningfully impact students who are more likely to enroll part-time, including:

• Adult learners (age 25+)
• Student parents and caregivers
• Working adults

Interventions may serve mixed-enrollment populations, so long as the proposed study is clearly designed to improve outcomes for these populations.
