Score Reliability for Tests Constructed for African-American Populations

Test score reliabilities and sample sizes (N) used to establish the reliabilities are described for a variety of tests constructed for African-American populations. The sample size was 341. The average internal consistency reliability was .74 ( SD = .16) with a median value of .77. The median N was 131. The mean internal consistency reliability and median N for tests intended for assessment of individuals were only .72 and 96, respectively.
