Psychological problems of labour education and vocational orientation of schoolchildren are discussed within the framework of the concept of life style. Life style is described as a stable system of modes of the life activity of an individual which developes through interaction of his personal qualities with objective requirements to particular life activities. The concept is applied to the study of such problems as correlation of labour education and learning activity, psychological testing of individual life styles, psychological taxonomies of schoolchildren developing under different conditions of labour education ad vocational orientation work. Some psychological criteria of labour educatedness are suggested which can be used to scale corresponding processes. The concept has been further confirmed in an experimental validation of a multi-dimensional procedure for checking the life style in senior schoolchildren (corresponding results are presented).
