The impact of sociocultural background and assessment data upon school psychologists' decisions

Fifty-six school psychologists participated in an adapted version of Algozzine and Ysseldyke's (1981) diagnostic simulation. The adaptation was designed to investigate the effects of sociocultural background (rural vs. suburban) and assessment data (normal vs. LD) on school psychologists' educational decisions. Knowledge of a student's sociocultural background did not influence these school psychologists' decisions; however, the type of assessment data had a strong impact. In contrast to the findings of Algozzine and Ysseldyke, the subjects did not ignore individual test data in favor of teacher referral statements. The school psychologists who received normal data were less likely to have low expectations for pupils' future academic attainment, to diagnose the child as LD, and to recommend special class placement. The subject school psychologists' perceptions of the importance of various diagnostic factors also agreed with their actual practices, as they reported that standardized test data figured prominently in their decision making. In short, this research suggests that school psychologists utilize multiple sources of information but rely primarily upon the more objective sources of information to make educational decisions.
