ENAccording to Audronė Vildžiūnaitė, authoress of the article "Some problems of adaptations of fifth-formers at school", adaptation of fifth-formers depends upon home environment, relations with parents, teachers, communication with classmates, success at school, microclimate at class. During the adaptation period behaviour undergoes changes. Improvement or disimprovement of behaviour depends upon success of adaptation. During in the adaptation period depressive states can show. In a case of successful psychosocial adaptation for a fifth-former, successful studies, socialization and communication with adults and contemporaries can be expected. Psychosocial adaptation is a critical process for a child to become a full-rate member of society or its group. This process is individual for each pupil.
