One hundred eleven subjects were asked to indicate how much relationship with people is involved in 48 occupational titles. The results support Roe's classification of occupations: differences within occupational fields were found to be smaller than differences between occupational fields (F=8.53, p less than .01).

A Vocational interests inventory-- "Ramak" --based on Roe's (1956) classification of occupations was constructed. It consisted of 72 names of occupations. Equivalent-test reliability of 0.76 was achieved. The inventory was validated on working samples and by the structure of intercorrelations. (Author)

Obtains a classification of occupations by interests based on an ordinal rather than on a nomial scale. The occupations in each field were found to be arranged in a hierarchical order. Two substructures, one comprising five and the other four fields of occupations, were established. (Author)

Israeli ninth-grade students (N=217) answered two interest inventories, one based on Holland's classification and one on Roe's classification. By means of a Smallest Space Analysis (SSA-I), a two-dimensional configuration was found. The findings indicate the possibility of incorporating results based on either classification. Some practical…
