As well, the board and head librarian need to appraise or evaluate the worth of their library programs regularly and volunteers too should be evaluated. Evaluation is used to judge or measure attitudes and ideas, programs, projects and goals. These judgements have to be based on objective evidence and they have to be made systematically. Poorly done, the appraisal of staff can damage relationships within the library, and often we don't appraise because we fear the process. It should not be repetitive or boring so that everyone involved wants to drop the process.
Good evaluation meets people on their own ground.
Standards used in evaluation should be those that will put the next improving step within easy reach of the group. The best evaluation is co-operative. Sharing the work of measuring progress leads all employees toward a deeper understanding and greater desire to improve than if some higher authority evaluates them. To be useful, evaluation must look at every aspect. Evaluators should consider everything related to the activities or undertaking being evaluated.
