The 1:3:25 option was developed by the Canadian Health Services Research Foundation (CHSRF) in order to ensure that research findings were presented in a logical and consistent manner
1:3:25 refers to a format that can be used to provide a consistent structure for final reports of any kind. The option allows for a one page outline of the main messages that have come from the research, a three page executive summary and 25 pages to present the findings and methodology used in a language that is clear and accessible to the non-research specialist.
The main messages contained in the first page should not be a summary of the findings but rather the key points that decision makers can take from the research. The three page executive summary presents the findings succinctly in order to facilitate easy access for those who may not have time to read the full report. This should not include any discussion of research methodology other than to outline the actual methods used. Finally, the 25 page report is used to cover the background to the research, the questions addressed, and an outline of the methodology, the findings and conclusions.
