The Central Government Services are organised into four groups, viz. Group `A' (which includes all- India Service) Group `B', Group `C' and Group `D'. Such classification broadly corresponds to the rank, status and the degree of the level of responsibility attached to the posts. Group `A' posts carry higher administrative and executive responsibilities and include senior management positions in the ministries/departments and field organisations. The middle and junior levels of Group `A' alongwith Group `B' constitute middle management. Group `C' posts perform supervisory as well as operative tasks and render clerical assistances in ministries and field organisations. Group `D' posts are meant for carrying out routine duties.
