The aim of investigation was to reveal the factors that have influence on choosing profession – intellectual capabilities and vocational predispositions. The subjects of the research were 304 second form gymnasium pupils (279 pupils from Vilnius Žemynos gymnasium and 25 pupils from Kaunas “Rasos” gymnasium). The age of the subjects was 15 – 17 years. Literature analysis, J. L. Holland’s test, R. Amthauer IST – 70 methodology, statistical analysis (SPSS 10.0 for Windows) were chosen as the research methods. All of our hypotheses were proved to be partly correct. It was found the positive relations between verbal capabilities (III subtest and I+II+III+IV subtests) and Investigative vocational predisposition, negative relations - between verbal capabilities (II subtest) and Conventional vocational predisposition; mathematical capabilities (V subtest and V+VI subtests) have positive correlations with Investigative and Conventional predisposition, but negative ones – with Artistic predisposition; mathematical capabilities (VI subtest) have positive correlations with Conventional predisposition. All the described correlations are very weak (0,190 ≤ r ≤ 0,276; p < 0,01; p < 0,05 and -0,280 ≤ r ≤ -0,194; p < 0,01; p < 0,05). The research revealed that verbal capabilities (II subtest) of Investigative and Social type subgroup’s are higher to compare to Conventional type subgroup F0,01; 0,05 (4,125) = 3,436; verbal capabilities (III subtest) of Investigative type subgroup are higher...
