The National Institute for Health Research (NIHR) is committed to making sure that each research study it funds has a clear and concise plain English summary. It is important that this information explains the research as a whole and is easy to read and understand. From 14 May 2014 a good quality plain English summary, submitted as part of the standard application form, will be a requirement of NIHR funding. Guidance has been developed for researchers and for board and panel members.
