To address the need for a harmonised, objective and transparent approach to assessing practical competence, Working Group 4 (WG4) of the Education and Training Platform for Laboratory Animal Science (ETPLAS) has developed a set of Direct Observation of Procedural Skills (DOPS) tools. These tools are tailored specifically to evaluate the intended learning outcomes of Modules 3.2, 6.2, 8 and 20-22 of the European Union (EU) Education and Training Framework. This report outlines the rationale, structure and guidance for implementing the DOPS tools. Based on Miller's pyramid and established educational principles, DOPS tools are suitable for formative and summative assessments in simulated or real environments. They can be used both formatively to monitor progress during training and summatively to support end-of-training decisions about competence. Their implementation is crucial to supporting harmonised training, facilitating mutual recognition of competence and ultimately advancing both animal welfare and the quality of scientific research in the EU and beyond. The DOPS forms are available as supplemental material to this article and from the ETPLAS website.</p>","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261436913"},"PeriodicalIF":1.3,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147839690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tasks like the euthanasia of surplus animals or being unable to alleviate animal distress due to scientific needs emerged as job-specific stressors. However, the results of the hierarchical regression indicated that general stressors, such as work-privacy conflict, physical and emotional demands, the need to hide emotions, and the degree of one's own influence at work, explained at least as much of the variance in psychological strain as the specific stressors. In addition, work experience, function, and gender significantly influenced the GHQ score.

Central to this process is incorporating the perspectives of stakeholders in biomedical research to develop practical and relevant strategies for action. In a qualitative study, we conducted 35 semi-structured interviews with Swiss researchers working on the 3Rs or animal experimentation. Interviews were analysed following a reflexive thematic analysis, and we identified two categories of facilitation: originative facilitation, which concerns epistemic aspects of the 3Rs, and executive facilitation, which concerns interventionist aspects of the 3Rs. In this article, we report on the former dimension, which can be further divided into the conceptualisation of the 3Rs on the one hand, and the education of researchers on the other hand. Although grounded in the Swiss context, these findings reveal key insights for researchers, policymakers, and institutional stakeholders internationally. As efforts to align animal research practices with ethical standards continue to grow globally, understanding how the 3Rs are conceptualised and taught is essential for creating coherent, cross-border strategies that foster responsible scientific practice. Clarifying definitions and reinforcing researcher education are critical steps in ensuring the consistent and meaningful implementation of the 3Rs across national boundaries.</p>","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261436225"},"PeriodicalIF":1.3,"publicationDate":"2026-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147723113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main aim of this study was to gain a better understanding of the importance of access to sheltered space for laboratory mice. We pair-housed mice (BALB/c, SWISS and C57BL/6, male and female) in conventional laboratory cages that contained either (i) resources to build underground shelter (burrowing substrate) or (ii) artificial structures providing shelter (e.g. red plastic house). We assessed how mice used these resources, as well as their preferences when given a choice between different shelters. In addition, we assessed the insulating properties of different shelters. Mice spent most of their time underground in deep bedding and the least time inside the standard red plastic house, where they nested outside the house. They also showed a strong preference for the deep burrow cage, and the most relevant features of preferred shelters seem to be darkness and being underground.
