U.S. social programs, set up to address important problems, often fall short by funding specific models/strategies ("interventions") that are not effective. When evaluated in scientifically-rigorous studies, social interventions in K-12 education, job training, crime prevention, and other areas are frequently found ineffective or marginally effective. Interventions that produce sizable, sustained effects on important life outcomes tend to be the exception. The Top Tier Evidence Initiative seeks to assist policy officials in identifying interventions meeting the Congressional Top Tier evidence standard, defined in recent legislative provisions as "well-designed randomized controlled trials [showing] sizeable, sustained effects on important outcomes." This evidence summary details and evaluates an intervention which provided streamlined assistance in completing the Free Application for Federal Student Aid, or "FAFSA"--which in 2008 was eight pages in length with over 100 questions, and included three additional worksheets with nearly 40 questions. Key elements of the assistance were: (1) specially-designed software used the family's tax return data to answer most items on the FAFSA; (2) the H&R Block tax professional conducted a brief (10 minute) interview with the family to answer the remaining questions; (3) the tax professional provided immediate estimates of the amount of financial aid the targeted family member was eligible for, and the net tuition cost of four nearby public colleges; (4) if all FAFSA information was complete, the tax professional offered to submit the FAFSA electronically to the U.S. Department of Education; and (5) if not all information was complete, a call center phoned the family after the interview to collect answers to the remaining questions and then facilitated submission of the FAFSA to the Department of Education. This intervention increased federal financial aid payments by an average of $375 per participant. The Panel finds that this intervention meets the Congressional Top Tier evidence standard. Intervention benefits and costs are discussed.
