The Berufsbilder Test, BBT-Br, is a projective method of psychological assessment for motivational inclinations and interests. This Swiss instrument was adapted for use in Brazil and has been studied for the last three decades, in the pursuit of its improvement for the Brazilian background. In line with this goal, the present work sought to formulate new normative references for both instrument versions (female and male), evaluating the possible effect of school grade and origin on the teenagers' production. The sample was composed by Brazilian high school teenagers, potential applicants for Vocational / Professional Guidance, where this instrument has presented positive relevant results. Furthermore, this study aimed to identify empirical evidences of factorial validity and accuracy for both male and female BBT-Br forms. Were examined 1582 protocols from both versions of BBT-Br, from which 862 were female students and 720 were male students, ages from 14 to 19 years old, from 1 st , 2 nd and 3 rd grades. They studied in both public and private schools from the interior of the state of São Paulo (Brazil). These cases were from a databank collected in the Research Center in Psychodiagnostic from the Faculty of Philosophy, Sciences and Letters from Ribeirão Preto. The results were prepared according to the BBT-Br versions, describing them in the way to compose new normative standards for this projective method, focusing productivity indexes and motivational inclination structure (positive and negative) from the teenagers, performing inferential comparisons (One way ANOVA) on gender, academic origination (public or private) and school grade. The accuracy of both BBT-Br versions was estimated by its inner consistency (Cronbach's Alfa) and exploratory factorial analysis (Principal Axis Factoring-PAF, with Varimax rotation) from the results were performed, determining extractions of four, five, six, seven and eight factors to test the best model to the data series. Once the most representative extraction was selected, the inner consistency of the found factors was verified. The results pointed to significant differences in the way teenagers select representative pictures of interests and rejections of professional activities, indicating specificities in the way of answering to the BBT-Br on gender, origin and school grade. The accuracy varied from 0,57 to 0,82, indicating good reliability indexes for both BBT-Br forms. The PAFs results pointed to a six factors extraction as the most representative of the data with accuracy from 0,72 to 0,90, indicating good reliability indexes for this factorial extraction. Current empirical evidences, altogether, indicated appropriate psychometric indexes to this projective instrument, adding scientific value and qualifying the use of BBT-Br in Brazilian sociocultural context, reinforcing its informative possibilities about motivation inclinations and interests in high school students.
