 The authors suggest an algebraic model of estimation of results of testing conducted in the form of traditional written examinations or contests with a complete solution of each task required. In this model solutions of the test tasks are evaluated by primary scores according to the traditional fractional scale. The advantages of the model are its simplicity, objectivity in measurement of the task complexity, estimation of students' preparation level by breadth and depth of their knowledge, opportunity of the objective ranking of the level of those participants who produce hardly comparable results.
