• PREPARE is integrated in the EQIPD framework for research quality control. It is part of the toolbox for this framework, and is cited on the pages covering animal characterisation and use, and ethical evaluation and authorisation.
• EFPIA published an Industry Statement on Experimental Design in 2019, which supports the use of PREPARE as one of three resources for planning, reporting and publishing in vivo studies.
• In the section of the UK organisation FRAME's website on publication of research, they recommend PREPARE when animal research cannot be avoided, as an aid in dissemination of the highest quality and reproducible research, to eliminate needless repetition of experiments and waste of animal lives and funding. 
• In the manuscript submission guidelines for the Journal of Psychopharmacology, authors are 'strongly encouraged to consult the PREPARE guidelines when planning their experiments'.
• An Opinion piece in the journal Shock in March 2020 states that, 'at the beginning of a study, the investigator should consider consulting general best-practice planning checklists, such as PREPARE'.
• The primer on research involving animals produced by the UK Research Integrity Office (UKRIO) in February 2019 described PREPARE as 'current best practice for laboratory animal science'. Version 2 of this primer, published in 2020, states that 'institutions can support researchers to consider all the topics which may influence the outcome of their studies and aid collaboration by promoting the PREPARE guidelines published in 2017, a good practice checklist for use when planning experimental procedures on animals'.  
• The University of Leicester​ 'supports the PREPARE guidelines and encourages all researchers to read through the checklist. The University and Home Office would also recommend the use of the PREPARE checklist for preparing grant applications.'
• On a page entitled Optimising animal studies, the University of Edinburgh writes that 'PREPARE acts as an aide memoire for busy researchers and gives them advice on all the issues which may affect the scientific validity and translatability of their research, as well as the animals' welfare'.
• The League of European Research Universities (LERU) has published Good Practice in Communicating Animal Research at Universities, and points out that 'initiatives such as: the PREPARE guidelines on how to plan animal experiments...are designed to deliver more reliable and translatable research. In addition, these exercises may lead to a reduction of unnecessary animal experiments'.
• PREPARE has been endorsed by Ellegaard Göttingen Minipigs (magazine article about PREPARE)
• PREPARE was highlighted in the January 2018 edition of the newsletter of the National Centre for the 3Rs (NC3RS) in the UK.

• On 20 February 2020 the National Committee in Greece issued a Recommendation stating that the PREPARE guidelines should be followed when designing an experimental protocol, pointing out that PREPARE focuses on a large number of factors which, although rarely referred to in scientific work, can affect the validity and outcome of animal studies, as well as the health and safety of all concerned.
• In a paper entitled Systematic review of guidelines for internal validity in the design, conduct and analysis of preclinical biomedical experiments involving laboratory animals, Jan Vollert and colleagues point out that 'only a few specifically address rigorous planning and conduct of studies, which might increase validity from the earliest possible point', citing PREPARE as an example.
• The PREPARE guidelines are recommended by the University of Zurich, who offer guidance on study design.
• Lund University in Sweden uses the PREPARE checklist in their requirements for scientists applying for permission to perform animal research.
