Intelligence Testing and Minority Students offers the reader a fresh opportunity to re-learn and re-consider the implications of intelligence testing. Richard R. Valencia and Lisa A. Suzuki discuss the strengths and limitations of IQ testing relative to the factors which may contribute to biased results.
