Online Peer Assessment (OPA) is a subject in recent studies about its validity in the teaching and learning process. Controversies are found in the literature, with students reporting discomfort during assessments. This research proposed the development of a framework to formation of heterogeneous pairs for OPA based on characteristics and attributes. A case study was conducted to understand the impact of this type of peer formation for better student acceptance during assessments. Greater comfort was detected during the assessment by students and also an indication of the contribution of the OPA to the student focused on the production, not feedback, of the evaluation.
