Gifted students are a heterogeneous group.
However, some methodological flaws exist in the study. While the experimental group had a mean IQ of 136.28 the control group had a mean IQ of 118.18. The global self-concept of both the gifted and accelerated groups were higher than those of the regular group. The U.S. students scored significantly below the international average on standardized tests at the twelfth grade level. Advanced U.S. students fared no better than their average classmates.
