The aim of the current study is to examine the variables that predict the sleep quality and academic achievement of children and adolescents from Turkey. Within this aim, 3677 students attending 4th, 5th, 6th, 7th and 8th grades in Sakarya province were selected through random sampling method and data regarding the gender, age, academic achievement, sleep quality, motivation, morningness-eveningness preference and sleep variables were collected. As a result; age, average sleep length, social jetlag, motivation and sleep quality were found to be significant associative factors of academic achievement. In addition, the significant associative factors of sleep quality were morningness-eveningness preference, age, motivation, average sleep length and gender and associative factor of morningness-eveningness preference were sleep quality, midpoint of sleep, motivation, social jetlag and gender. These results show that the sleep patterns and sleep qualities of the children and adolescents during the week days and the weekend should be taken into account while examining academic success. Moreover, the fact that the morningness-eveningness preference is related to the sleep quality and motivation of the children and adolescents represents the importance of their morningness-eveningness preference preferences in academic outcomes, albeit indirectly.
