trainee after a period of one week of training. At approximately two months, follow up reports are sent to the trainee. The certificate of completion of training is issued to the participants after the feedback is received. Meeting the objectives set while designing and conceptualizing training is one of the main methods of measuring behavioral changes. Performance appraisal suffers the same type of bias as measuring emotional reaction by questionnaire when applied to measuring behavioral changes. Here the trainee supervisor is the individual who might be bias. Performance appraisal literatures seem to be aware of this shortcoming. The techniques of reducing evaluator bias includes using subordinate, peer and trainee feedback. The subordinate feedback is important as the trainee’s subordinate is the direct recipients of behavioral changes and performance improvement. Peer feedback will give a closer analysis of behavioral changes since peer performed the same function alongside the trainee and finally, self feedback in a time series manner can be cost effective ways of measuring program towards meeting behavioral changes objectives. By using the three techniques, the likely bias of evaluation will be reduced to insignificant level or totally eliminated.
