Based on the results published by Patrick's team in 2014, 2015 and OECD 2015, this article proposes 4 assessment levels corresponding to each specific criterion of three component competencies: (1) establishing and maintaining shared understanding; (2) taking appropriate action to solve the problem; and (3) establishing and maintaining a team organization. The paper also proposes a matrix of assessment toolkits and corresponding criteria of collaborative problem solving competence in teaching chemistry of the non-metals using interdisciplinary integrated teaching perspective and Kolb's Experiential Learning Cycle. Each assessment tool specifically analyzes the functions and techniques implemented in students' collaborative problem solving processes. Keywords: Competence, collaborative problem solving competence, interdisciplinary integrated teaching, Kolb’s model. * _ * Corresponding author.
