    Facility and Mastery: Student performance in CQ Differential Calculus is measured on the basis of demonstrated proficiency in the application of Objective skills. It is recognized that each skill can be measured against progressively more demanding leve ls of proficiency.

    Level 1.
    Students demonstrate competence with a particular skill through successful application of the skill in problems that call for that skill explicitly.

    Level 2.
    Students demonstrate conceptual and contextual understanding of a particular skill through successful application of that skill in problems which require the skill implicitly and yet do not call for that skill explicitly. This l evel of proficiency demands at least these components.

    Level 3.
    Students demonstrate overall mastery through successful application of *multiple* Level 1 and Level 2 skills in problem-solving situations. Level 3 problems require the formulation of nontrivial solution strategies that combine applications of various skills.
