One of STD (self-determination theory) components is basic psychological needs that emphasizes on Relatedness, Competence and Autonomy to accomplish the motivation. Motivation involves the processes that energize, direct, and sustain behavior. It seems that school culture, basic psychological needs and motivation has immense effect on academic achievement. The purpose of the present research was to examine the relation between studentsʹ perceived school culture, basic psychological needs, intrinsic motivation and academic achievement in a causal model. 296 high school students (159 females and 137 males) in Tabriz, north - west of Iran, participated in this research and completed the studentsʹ perceived school culture questionnaire based on Hofstedeʹs cultural dimensions (femininity, uncertainty avoidance, collectivism and power distance), basic psychological needs and intrinsic motivation. The results of the path analysis showed that fulfillment of basic psychological needs and intrinsic motivation has positive effect on academic achievement. Uncertainty avoidance and power distance have also negative effect on fulfillment of psychological needs, but the influence of femininity on this variable was positive. Also, collectivism has no significant effect on it. In general, the findings showed that if school culture supports studentsʹ autonomy, they will experience fulfillment of their basic psychological needs, and attain higher intrinsic motivation and academic achievement.
