The scale was administered on totally 94 students. 26 of them were male, 68 were female. It was determined that reading comprehension skills were differed significantly in terms of gender variable and that female students‟ level was higher than that of males‟. Even though male students‟ levels were determined relatively lower, they were found to be better and more practical than female students in terms of using these skills actively and multi-dimensionally. While the level of reading comprehension skills was determined higher among the students who graduated from public high schools than the ones who graduated from schools admitting their students through entrance exams, the latter students were observed to be more skilled than the former ones in terms of using their reading skills.
