The Governor's School of North Carolina is a residential summer program for talented and gifted juniors and seniors from all over the state. It is designed to provide a distinctive educational experience and to serve as an experimental laboratory for innovative instruction. This handbook reports on an extensive testing program carried out at the school in 1963, 1964, and 1965. The test battery covered intellectual aptitude and ability, creativity, personality, adjustment, interests, values, attitudes, and motivation. The six measures used are described and the results are tabulated by sex, division (academic or arts), section (English, French, Painting, etc.), and by subsets of these categories. Twenty-six Adjective Check List (ACL) profiles, 26 Minnesota Multiphasic Personality Inventory (MMPI) profiles, and 26 Strong Vocational Interest Blank (SVIB) profiles are included. It is suggested that these test results may be used for comparison with other groups of gifted or unselected adolescents. Suggestions are given for primary, secondary, and tertiary levels of analysis. Each of these is illustrated by use of the Governor's School results and national norms or other published results for one or more of the tests. Each of these analyses has considerable intrinsic interest. (Author/DG)
