The aim of the study - to analyze the main factors of learning achievements of intellectually gifted children. The sample consists of 16 - 18 year old students (N = 54), whose Reasoning Total (RT) scores in Intelligence Structure Test 2000R (I-S-T 2000 R, Amthauer R., Brocke B., Liepmann D, Beauducel, 2001) are 90 percentile or higher. This thesis analyses the peculiarities of intellectual activity of intellectually gifted 16- 18 years old students, their learning achievements and has the objective to determine individual and environmental factors of their learning achievements. The results show that Intellectually gifted 16 - 18 year old students have unique intelligence structure when fluid intelligence (Gf) is higher than crystallized intelligence (Gc) and numerical abilities are higher than verbal abilities. Part of older intellectually gifted students are underachievers and their learning achievements are not related to their intelligence. Learning motivation, study/organizational skills and gender are the most important factors of learning achievements of intellectually exceptionally gifted and gifted 16 - 18 year old students and they not depend on the level of their intellectual abilities.
