There is a global shortage of individuals with the knowledge, skills and expertise necessary to undertake in-vivo or whole animal research. To address this skills shortage, many countries, including the UK and the US, have committed significant funds towards training the next generation of in-vivo scientists within their respective countries. There is also a need to provide for continued professional development (CPD). Indeed, the new European Union animal welfare directive 2010/63/EU makes such training mandatory. This training and CPD would be best facilitated with short open educational resources (OERs) or learning objects (LO) and therefore the aim of this project was to collate, evaluate and disseminate OERs and LOs that could be used in educational and training in in-vivo sciences. Open educational resource repositories and websites of professional and other organisations were searched for suitable OERs and LOs (eg video podcasts, guidance notes, statistical packages). A call was also made to colleagues in relevant professional bodies. Individual resources were evaluated and a brief description of each written. These were then collated into an education and training resources in in-vivo sciences (ETRIS) wiki, subdivided into topics across the entire spectrum of resources required by practicing in-vivo scientists including surgical procedures, animal welfare and husbandry, ethics and the 3Rs, experimental design and analysis. This wiki is now being made freely available to colleagues. ETRIS will be of significant benefit and a valuable tool for colleagues engaged in education, training or research in in-vivo sciences. It is envisaged that it will be a living wiki, that will grow as colleagues either contribute or provide links to new OERs and LOs.
