The aim of this work is to define informational criteria of optimization of group cooperation in training process with the help of clusterization of training contingent. The finding management criteria of clusterization procedure is built on the principle of entropy minimization and is realized according to two informational chanals. Firstly, an the results of the subject testing of the training contingent. Secondly, on the sociometrical data with the help of measurement of matrix`s sympathy of the training contingent.
