ENThe aim of this paper is to analyze the theoretical foundations and practices of parliamentarians' qualification development for a successful functioning of the Parliament and to introduce the empirical research related to the attitudes the Lithuanian parliamentarians towards training and participation in educational programs. The empirical research showed that qualification development of the Lithuanian parliamentarians is not systematic and the attitudes of the Lithuanian parliamentarians towards qualification development are ambiguous: from considerations that such activities are a waste of tax payers' money to taking personal responsibility and active involvement in qualification development. The system of qualification development of the Lithuanian parliamentarians should be improved. Special attention should be paid to the parliamentarians' consciousness, ability to understand their own limitations and readiness to learn.
