The document discusses ways to bring dropouts back into education. It presents a conceptual model showing the stepwise progression of education from early childhood through career. To help dropouts, it suggests blurring the vertical boundaries between education levels by making admission requirements less rigid, such as with pre-apprenticeship programs that combine learning and working. It also recommends blurring the horizontal boundaries by building on a student's identity or life interests through tailored programs. The goal is to create a more flexible education system that better engages at-risk youth.
