The paper discusses ratios of health markers in adolescents which is part of the work of a school psychological service. A complex psychological and psychophysiological study of 92 senior students of mass schools and gymnasiums has been carried out to find out the indices of the intellect and the adjustment potential, measured with the help of express methods and the method of stochastic non-linear cardiointerval measurement. It has been discovered that the adjustment potential of gymnasium students is higher than that of mass school students. There is also a correlation between indices of the cardio-test and express methods reflecting the adjustment potential and normal health which are better in gymnasium students.
