Purpose When using embedded, student-centered assessment tools for maker education, understanding the characteristics of a body of evidence can help teachers guide the assessment process. This study aims to examine assessment artifacts from a makerspace program and present a set of qualities that emerged, which researchers and maker educators can use to evaluate the quality of evidence before interpreting it and making claims about student learning. Design/methodology/approach This study used the interpretive analysis approach to identify salient qualities in a body of evidence of maker learning. Data sources included student assessment artifacts, researchers’ analytic memos, notes on the coding and analysis process, background stories and field observations. Findings The study found that the assessment artifacts generated by students aligned with the maker-related target skills. A set of qualities was produced that can be used to describe the strength of a body of evidence and help determine whether it is appropriate to be used in the meaning making phase. Practical implications The qualities identified in this study can be directly incorporated into the embedded assessment toolkit to provide feedback on the strength of evidence for learning in makerspaces. Originality/value Assessment methods for maker education are nascent, and ways to describe the quality of a student-generated body of evidence have not yet been established. This study applies existing knowledge of embedded assessment and reflective practice toward the creation of a new way of assessing skills that are difficult to measure.
