From ESER: Over the past 25 years, evaluations have produced a great deal of research on interventions designed to improve the employment outcomes of low-income adults. But, the quantity and diversity of the findings can make it challenging to identify the most reliable and relevant research and learn from it. The Employment Strategies for Low-Income Adults Evidence Review (ESER) was designed to make this research more accessible and easier to understand. ESER is a systematic review of studies published between 1990 and mid-2014, in which reviewers examined research about employment and training interventions for low-income adults.
