n the paper the Russia Longitudinal Monitoring Survey data sets (2000-2006 years) are used to test screening hypotheses. According to the strong hypothesis individual's productivity is unaffected by the schooling, education serves only to identify more productive individuals and education credential could be used exclusively as a signal of individual's innate productivity. While the primary role of schooling is to signal, according to the weak hypothesis education may also augment inherent productivity. Empirical part of the paper is based on the estimates of Mncerian-type equations. As the result we have find evidences of the weak screening hypothesis and reject the strong hypothesis at the Russian labor market. In addition at the end of the paper it is shown that females' return to education decays not so fast with the firm experience increasing in contrast to males.
