Published: November 2003


SCIE, in the formation of its good practice guidance for the social care sector seeks to include all relevant kinds of knowledge and strongly believes that it is only through looking at the sector from a whole perspective - including the views of service users and practitioners - that we can truly advise social care workers on what works best.

But this does not mean that all knowledge is equally good or useful. It may be badly collected or recorded, make unjustified claims or ignore evidence from other sources. SCIE wanted to be sure that its good practice guidance was based on the rights types of knowledge and on the right quality of knowledge.


This review is the first stage of a project looking at the evidence-base for social care. The knowledge review identifies the main types of research, experience and wisdom that combine to form the social care knowledge base and proposes a framework for assessing the quality of knowledge of any type.


This review is intended for use by SCIE to inform future systematic reviews (A systematic review is a systematic and rigorous review of all available evidence, designed to eliminate bias and assemble as complete as possible a picture of the knowledge available in social care) which SCIE uses as the basis of its good practice guidance. It is also intended as a resource for other researchers in the social care sector.
