This article reports on assessments of business letters assigned to students in a business communication course. Assessments were performed by faculty in other disciplines and local business professionals, with each sampled assignment evaluated by one faculty and one business professional. Overall, the assessments by the two groups were similar in terms of evaluation items related to quality of content and organization. However, faculty evaluators rated the letters lower on items related to mechanics, while business professional evaluators rated the letters lower on items related to professionalism. The paired assessments revealed only limited consistency between the two evaluator groups.
