Abstract: The Republic of Tatarstan Law "On languages of people of Tatarstan Republic" and other laws and regulations intend Tatar language study (both native and foreign to students) in Republic's educational establishments to be obligatory. Current study describes information-and-communicational technology use the part it plays in school education and its possible application for teaching Tatar language in mainstream schools. Thus, informatization of learning process is currently considered an integral part of forming many-sided personality. In current conditions, it is necessary for a teacher to know the roles of modern informational technologies’ wide variety, ideas, schools, branches in order not to waist time on making overdue discoveries but to use all repertoire of Russian pedagogical experience. Exploring this problem and real world application of the results in educational system enable us to draw the conclusion that information and communication technology use dramatically increases Tatar language study quality and effectiveness during the whole school period. Still, information and communication technology use does not rule out traditional Tatar language study forms and methods. Both of these learning techniques must harmoniously merge on all school education stages.
