I have been using specifications grading in my undergraduate courses since Fall 2017.  Currently, I use this system to teach General Psychology I (PSYC 1100), Principles of Research Methods (PSYC 2100WQ), Abnormal Psychology (PSYC 2300), and Developmental Psychology (PSYC 2400).  I have also used this grading system for numerous 1-credit course (UNIV 1820, UNIV 3995).  I have been a member of a Specifications Grading Learning Community through the Center for Teaching and Learning (CETL) and have given numerous workshops and presentations about this grading system.  I have included syllabi for some of my most recent courses, as well as assignment instructions for reference.  You can also find peer reviewed articles about this system from multiple disciplines like Speech and Language, Mathematics, and Political Science, but this list is not exhaustive.
