State anxiety describes a condition when confronted with a specific situation causing genuine concerns.High school students may face such a situation in the preparation for state examinations. Thus, we aimed at not only studying state anxiety in such students, but also at performing psychocorrection of this condition using a specially created programme. The psychocorrection programme is designed to establish the basis for and develop a positive mindset towards the upcoming challenges, or the state examinations, to help students understand their goals and priorities, to teach them techniques of relaxation and muscle and mental tension relief, breathing exercises, and control of emotions. The programme was implemented in the Rudny school No. 2 in the Kostanay region of Kazakhstan. The sample comprised 25 students, including 14 female and 11 male students. We applied the technique proposed by Charles D. Spielberger and adapted by Yu.L. Khanin, the state anxiety scale by Kondas, and the Non-Existent Animal projective technique. As seen from the findings, in the process of psychocorrection the normal level of anxiety started to prevail. The success of state anxiety correction in high school students is linked to the increase in their self-esteem and selfconfidence, their mastering of the muscle and mental tension relief techniques, and the development of their self-control skills
