Evaluation Bias and Its Control. Paper #4 in Occasional Paper Series.
Selected aspects of the problem of obtaining unbiased program or product evaluation are discussed. An evaluator who is a member of the project staff will have difficulty producing an evaluation which is credible and valid. Project monitors will also have a problem since they are often required to assume the conflicting roles of external evaluator and project advocate. Therefore, no unit should rely entirely on a given subunit for evaluative feedback about that same subunit. Evaluative feedback systems require renewal or replacement to prevent deterioration of their independence. Evaluators should arrange for replication of their own work by independent evaluators. Four further approaches for reducing bias in evaluation include: (1) standardizing the qualitative aspects of evaluation procedures by using a checklist; (2) upgrading evaluator training procedures; (3) reducing sources of bias external to the evaluator; and (4) comparing the project, programs, or products with alternatives.
