Abstract
The role of evaluator is virtually universal among technical services librarians. The extent to which political elements intrude in the evaluation process is not always recognized, but any perceptions of unequal bias will erode motivation and organizational effectiveness. Various studies suggest that elective inflation to ratings is more prevalent than conscious deflation. Formal standards, when carefully maintained, can clarify management expectations; enable employees to selfmonitor production; render the evaluation event more predictable and the task of giving negative feedback more impersonal; reduce perceptions of political or personal bias; forestall frivolous litigation by employees; and increase productivity and morale. Formal standards require careful monitoring of work flow and of factors influencing production, and revisions to standards at times may be required. Consistency in the application of standards among staff is essential. The costs of maintaining standards should be weighed against the likely benefits to the organization.
