Factor structure of the graduate record examinations general test in handicapped and nonhandicapped groups
Article Abstract:
We used confirmatory factor analysis to investigate the structure of the Graduate Record Examinations General Test across handicapped and nonhandicapped groups. A simple three-factor model, consisting of verbal, quantitative, and analytical item types, was posed and tested for model fit. In addition, a higher order factor solution was computed to investigate the meaning of General Test total scores and to probe observed discrepancies in factor structure. Results suggested that the three-factor model fit better than simpler models but less well than a four-factor solution. The three-factor model showed particular problems in fit for visually impaired students taking a large-type examination and for physically impaired examinees taking a standard administration. For these groups, the item types composing the Analytical factor did not appear to function effectively as a single factor. For the large-type group, in particular, these item types exhibited different relations with the other factors, had different relations with the test's general factor, and appeared to produce different scale units. Results suggest that Analytical scores and total scores (Verbal + Quantitative + Analytical) may have different meanings across handicapped and nonhandicapped groups.

Structural Validation of Holland's Hexagonal Model: Vocational Classification Through the Use of Biodata
Article Abstract:
An assessment of the constitutional validity of J.L. Holland's six-faceted vocational model is offered. Methodology references include the personality inventory consisting totally of occupational titles, completed by the subject on the basis of interest likes and dislikes. The Vocational Preference Inventory (VPI) encompasses the hexagonal types classified as realistic, investigative, artistic, social enterprising and conventional (RIASEC). The RIASEC components correlated with biodata statistics to predict VPI figures for more than eight hundred men and women, to validate the model's composition. The principal result of the study shows that the data in Holland's model of vocational roles is borne out, despite some problems with types and classification research. Statistical tables record analyses between actual and predicted ratings in terms of which biodata factors were applied to which gender.

Assessing Raters' Policies in Evaluating Proposed Services for Transporting the Physically Handicapped
Article Abstract:
The types of research used to evaluate potential means of transport for the physically handicapped are discussed. An equation was devised to correlate occupation with how much celebration was applied to the question, in addition to cost issues. The formulation design specified one contingent variable: an approved rating for accessory currier equipment. Department of Transportation (DOT) employees, who had studied a great deal about disabled students' problems, emerged with predictive ratings and opinions. Multiple regression analysis defined which area made the most impact upon the participants; the cost factor did not affect DOT Workers to any noticeable degree. The results pointed to an enigma in terms of who should decide policy; judicious, thoughtful lay people or officials with technical expertise.
