This communicaton shares with the chemistry education community the rubrics used to evaluate student videos associated with using a pipet, using a buret, and making a solution in a volumetric flask that were part of a digital badging project. The rubrics were used across multiple general chemistry courses, hundreds of teaching assistants, and thousands of students. Guidelines for implementation of the rubrics, including the training of teaching assistants or groups of graders, are provided.
