PURPOSE OF EVALUATION:

The purpose of  evaluation of service is to answer the questions, "To what extent and how well did the programme meet the objectives of  the service?'  It is concerned with both effectiveness (outcome) and efficiency (methods). For example, if  a sanitation programme in housing related  to  cleaning up the great majority of housing violations, it &ght  have been highly effective. If, however, the cost of inspection was unduly high, because of poor scheduling or if  the preparation of  records used an inordinate amount of  time, the programme might not have been an efficient one. Evaluation  is necessary for

• The modification of  the programme to be at par with the problem arising in the community or with the felt need of the community. 
• Ensuring objectives for the continuing education of  the staff members for their development.
• Serving as basis for diagnosis of professional problems and potentialities. 
• Forming a basis for the future plan of the programme. 
• Helping in the research studies for innovation in the community health nursing services. 
• Providing a review of  the standards of work for both  the supervisor and staff. This may serve to emphasize, clarify or modify existing standards.
