Expectancy effects and their relationship to psychological case report writing

The present study examined the relationship between the psychological evaluation reports of test examiners and the referral questions of classroom teachers. It was hypothesized that there would be an interaction between examiners' reporting of test data and the information that was received from school personnel. Data were analyzed using a 2 X 2 chi square analysis. Results indicated a biasing effect when examiners were knowledgeable about the reasons for referral.
