The idea that HS grads could “take a year off” and do some “useful learning” before college, is ironic as well as economically brilliant (one year not paying tuition)…but creates a “class of worker” that is exactly what PSA would like to engage and “put to work” on DLE projects. Viva las Gap Year!

Prefer a better name than “Gap Year”…perhaps “Public Service Apprenticeship” instead.
