In accordance with a Ministerial Resolution of the Argentine Republic, a tertiary level teaching institute was authorized to offer a post-graduate course for teachers entitled, "Interpersonal Relationships at School." The possibilities of didactic games are examined as an expression of a formative continuous evaluation which stimulates spontaneity while it provides formal guidelines to evaluate the individual's potential expressed in games and the individual's learning achievement. Based on systems theory, this program analyzes the school; its component sub-structures; and its transactional levels, including institution-environment, different work groups, and individual-institution. The following of rules for the beginning, development, and evaluation of the applied circumstances differentiates the games from role-playing and standardized tests. The games are related with various sub-themes of the interpersonal relationships program theme. The specificity of pedagogical objectives facilitates the measurement of achievement. Observer's records are compared with the teacher-completed evaluation schedule. An application of the game (a leadership action theme) and its corresponding evaluation schedule are described. This method has effectively achieved its objectives: to verify the degree of internalization of the concepts developed during the game application. (Author/PN)
