The aim of this study is to design and validate an instrument that allows the evaluation of educational experiences and formative assessment in the metaverse from a holistic perspective. Hence, a research design based on the development of a scale has been used. Three hundred and sixty-two Spanish secondary school students participated in the study, selected through purposive sampling. The instrument created has been subjected to an analysis of content validity, validity by expert judgment, construct validity, and reliability. For data analysis, the SPSS and AMOS programs have been used. An exploratory factor analysis and a confirmatory factor analysis have been performed to determine the construct validity. In addition, the Cronbach's alpha has been calculated to verify the internal consistency of the tool. The results reveal several findings that position the resulting questionnaire as a valid and reliable instrument to evaluate educational experiences and practices in the metaverse. In short, this study has led to the development of a comprehensive evaluation tool at the service of educators or any institution interested in implementing its educational praxis within the metaverse, a field of research that has yet to be explored.
