An evidence gap map is a visual summary of how much published research exists on a topic. Evidence gap maps can identify gaps in research, highlight topics that need further study, and support decision making.
These five evidence gap maps show the quantity of existing evidence about the effects of different employment and training services on employment, earnings, public benefit receipt, and education and training outcomes for workers with low incomes. Each map helps answer different questions.
