Eleven staff radiologists evaluated resident performance by independent subjective ranking regardless of residency year. A pooled ranking correlated with a ranking obtained from the total raw score of the American College of Radiology (ACR) Inservice Examination (P <.005). The staff pooled ranking had a Spearman rank correlation, r =.70, with resident overall performance upon the ACR Inservice Examination. The pooled ranking had a Spearman rank correlation, r =.90, with a subsequent pooled ranking obtained six months later (P <.0001). This method of ranking accurately predicts ACR Inservice Examination performance and appears to evaluate the objectivity of the staff radiologists involved.
