This document was produced by the authors based on their research for the report, "Who Are the Persistently NEET Young People? NCVER Research Report," and is an added resource for further information. The purpose of this document is to review some of the main research and literature on young people aged 15-24 that are not engaged in education, employment, or training (NEET) to help inform the research project. The review is not intended to be comprehensive but rather provide a baseline of understanding for the current project. [For "Who Are the Persistently NEET Young People?
