Ethical Interpretation of Intelligence Tests: Considering Critical Sources of Psychometric Evidence

Workshop Summary:

Interpretation of intelligence tests involves making inferences about the characteristics of the person assessed based on the obtained scores. Most intelligence tests provide numerous scores and numerous score comparisons for interpretation. Interpretations and resulting inferences must have empirical support of score reliability, validity, and utility according to the Standards for Educational and Psychological Testing (American Educational Research Association [AERA], American Psychological Association [APA], & National Council on Measurement in Education [NCME], 1999). Ethical standards also proper test use and interpretations based on psychometric support.


This workshop focuses on psychometric and ethical principles that should influence and guide interpretation of intelligence and cognitive ability tests; uses of intelligence tests in psychological practice; psychometric evidence for various intelligence tests and what they purport to measure; empirical methods for establishing score reliability, validity, and utility; issues of language and ethnicity/race; and current practices in IQ test use such as cross-battery assessment.


The goal of this workshop is to sensitize attendees to issues, research, and questions pertaining to the use of intelligence tests in assessments of children and adolescents suspected of various disabilities. There are many recommenced interpretation practices for IQ tests proffered by various authors and/or test publishers but most have little to no empirical support. Because test users are ultimately responsible for the ethical use of intelligence tests including selection, administration, scoring, and interpretation; it is the test user who must weigh the evidence and deal with the issues concerning IQ tests. In the cogent words of Wiener (1989), psychologists must “(a) know what their tests can do and (b) act accordingly” (p. 829).
