“…One hundred and fifty-four empirical studies and 27 test manuals met inclusion criteria, from which 378 comparisons were extracted, 285 of which were normed more than 5 years apart. The chronological range of the Flynn effect data collected was from 1951 upon publication of Weider, Noller, and Schramm’s (1951) comparison study of the WISC and SB to 2010, the year in which the literature review was completed. Table 1 shows the effect size produced by each of the 378 comparisons and includes information pertaining to sample size and age in months.…”

The “Flynn effect” refers to the observed rise in IQ scores over time, resulting in norms obsolescence. Although the Flynn effect is widely accepted, most approaches to estimating it have relied upon “scorecard” approaches that make estimates of its magnitude and error of measurement controversial and prevent determination of factors that moderate the Flynn effect across different IQ tests. We conducted a meta-analysis to determine the magnitude of the Flynn effect with a higher degree of precision, to determine the error of measurement, and to assess the impact of several moderator variables on the mean effect size. Across 285 studies (N = 14,031) since 1951 with administrations of two intelligence tests with different normative bases, the meta-analytic mean was 2.31, 95% CI [1.99, 2.64], standard score points per decade. The mean effect size for 53 comparisons (N = 3,951) (excluding three atypical studies that inflate the estimates) involving modern (since 1972) Stanford-Binet and Wechsler IQ tests (2.93, 95% CI [2.3, 3.5], IQ points per decade) was comparable to previous estimates of about 3 points per decade, but not consistent with the hypothesis that the Flynn effect is diminishing. For modern tests, study sample (larger increases for validation research samples vs. test standardization samples) and order of administration explained unique variance in the Flynn effect, but age and ability level were not significant moderators. These results supported previous estimates of the Flynn effect and its robustness across different age groups, measures, samples, and levels of performance.

“…In several studies, the Stanford-Binet, Form L, and the Wechsler Intelligence Scale for Children (WISC) were administered to the same children, at the same age, by the same examiner (2,5,7,9,10,11,12,13,15). The following results were obtained: (a) The median correlation between the Stanford-Binet and the WISC Full Scale IQ was .85.…”

“…Recent studies comparing Wechsler Intelligence Scale for Children results with Stanford-Binet results indicate that mean IQs on the Wechsler Intelligence Scale for Children tend to run a bit lower than mean Stanford-Binet IQs especially for children under eight years of age. A report by Weider and others (10) listed the correlation between StanfordBinet, L, and the Wechsler Intelligence Scale for Children full scale as .89.…”
