Published by NIACE in partnership with the National Research and Development Centre for Adult Literacy and Numeracy (NRDC), this is one of a series of guides to good practice each in a key area of adult education arising from five Effective Practice Studies carried out by NRDC from 2003 to 2007. The series looks critically at how emerging and published research can inform the development of teaching and learning strategies for adults. It is designed to support practitioners working in a variety of settings.
