The Lifelong Learning Demonstration (LLD) in the Greater Baltimore area was designed to encourage adult workers to invest in education and training (ET) to upgrade their skills, productivity, and earnings. To test achievement of this objective, an evaluation estimated LLD's impact on school enrollments, number of credits earned, receipt and amount of financial aid, and receipt and amount of Federal Direct Student Loans. Over 200,000 people in the sample were randomly assigned to treatment and control groups. LLD did not have a statistically significant impact on educational outcomes during the two-year follow-up period. The treatment--a brochure providing comprehensive information on ET opportunities and making it easier to acquire more career, school, and financial aid information--was not a strong enough intervention to change workers' behavior. LLD did not have an impact on ET participation. Younger adults, females, single workers, workers with postsecondary degrees, and people with outstanding loans were more likely to participate in ET. Nearly 75 percent of students had some college education; over half were married; over half were over age 35; more than 70 percent worked for employers who offered tuition reimbursement; mature incumbent workers bore significant costs to participate in ET; and students made a number of lifestyle adjustments to participate in ET.
