As part of ongoing efforts to reduce waste and increase the reproducibility of animal research and testing, a group of experts from the UK and Norway, led by the Secretary of Norecopa, has produced a set of guidelines for planning animal experiments:
PREPARE (Planning Research and Experimental Procedures on Animals: Recommendations for Excellence)
The PREPARE guidelines for planning animal experiments complement reporting guidelines such as ARRIVE. PREPARE focuses on a large number of factors which, although they are seldom reported in scientific papers, can dramatically influence the validity and outcome of studies on animals, as well as the health and safety of all those concerned. PREPARE covers all stages of quality assurance, from the management of an animal facility or population to the individual procedures which form part of a study. The guidelines and checklist are based upon the authors' experience over the last 30 years in running accredited animal facilities, collaborating with researchers (including those working with farm animals, fish and wildlife), serving on advisory and regulatory committees, and planning their own animal studies.
We recommend a 3-step approach to animal research:
- Use of the PREPARE guidelines from day 1 of planning, collaborating closely with the animal facility
- Use of reporting guidelines such as ARRIVE to ensure the quality of the manuscript to be submitted
- Highlighting any advances in the 3Rs (Replacement, Reduction or Refinement) made during the study in the manuscript's title and/or abstract (since many databases only index these parts of the paper)
PREPARE is NOT "yet another checklist to prove compliance"!
It is an aide memoire to remind scientists of all the topics which may be relevant when planning experiments, in the same way as even experienced pilots use several checklists on routine flights. Many of these topics do not need to be reported, but they are vital for the success and validity of the experiment, for health & safety, and for animal welfare.
The 15 topics in the guidelines, with a large number of links to other more specific guidelines and resources, are discussed under the sections in the menu above. They include a suggestion for a contract between the animal facility and research group, to aid division of labour, costs and responsibility.
A 2-page checklist, available in many languages, can be downloaded here.
Links to new resources will be added as they are developed.
PREPARE will therefore be a living and dynamic set of guidelines which mirror developments in best practice within the field of research animal science and 3R-alternatives.
Endorsement and citations of PREPARE
The PREPARE guidelines are rapidly gaining acceptance in the international community. We have constructed a separate page listing some of the endorsements which PREPARE has received.

The list of items in PREPARE is offered as a guide and should be adapted to the individual research project, animal species and location. Some elements will be the responsibility of the animal facility itself, rather than the individual research group, since they determine the standard of the facility as a whole. However, a research project often raises questions which are not covered by the facility’s normal work routines. These include activities which have potential health and safety risks, such as the use of micro-organisms, ionising radiation and carcinogens. Early and open dialogue between the facility and research group, to create a good atmosphere for collaboration, is therefore essential. For example, if a facility cannot safely conduct an experiment without structural changes or investment in new equipment, this should be discussed with the research group at an early stage, however tempting it may be to start collaboration on a prestigious project. Animal welfare and ethics committees can be a useful forum for some of this dialogue.

The costs of Open Access publication of the PREPARE guidelines and the production of conference posters were kindly provided by the Universities Federation for Animal Welfare (UFAW). The paper was pre-published on 3 August 2017 and published in the paper version issued in April 2018.
