| Facing legal, professional, and scientific concerns about the fairness of intelligence testing, especially with cultural and linguistic minorities, researchers point to local norms as a promising alternative. Nonverbal instruments are easy to translate and to adapt to a different culture, making the process of obtaining local norms very economical.;The research with the PTI (French, 1964) suggests adequate potential for adaptation to a sample of Puerto Rican children ranging from 5 to 8 years of age. After careful translation and adaptation of content, items of poor discriminatory power were eliminated, and the order of administration was rearranged, following results from item analysis conducted in Puerto Rico.;The result of this process is PTI Puerto Rican norms for children of ages 5-0 to 8-11. Descriptive statistics are provided as well as derived scores in the form of Deviation IQs and percentile ranks. |
