A core principle of specifications grading systems is to align assignments with course LOs, and a key structure of these systems is bundling these assignments together to determine course letter grades . Four main methods to bundling, which we call configurations, emerged in the analysis of peer-reviewed descriptions of specifications grading. Tsoi et al. originally described three main configurations (called "implementations") in the context of lecture courses: core and additional LOs, all equal LOs, and modules . A fourth configuration best described as all equal LOs with repetition and/or complexity (ELORC), arose in the context of laboratory and writing courses.
