The scholarship related to Assurances of Learning (AoL) has really taken off since the accreditation agencies adopted this requirement in 2005. In addition to the standards themselves, the Joint Committee on Standards for Educational Evaluation (JCSEE) for program evaluation (JCSEE, 1994) and student evaluation (JCSEE, 2003) are good places to start reading.
There are three levels of AoL: individual student grades, assessing groups of students for instructional planning, and evaluating program-level outcomes over time. Unfortunately, these three levels require different methods. The accreditation agencies prefer methods that assess overall program level outcomes, whereas professors prefer to focus on student-level grading methods. The course-embedded method attempts to resolve this by using student grades on assignments as the basis for program-level assessment (Martell, 2007).
