Results of representative survey among Lithuanian population (2016) show that public trust in civil service organizations and public officials is moderate (6 points of 10). Statistical analysis reveals that level of the trust is predetermined by individual (i.e. the officials’ responsibility, respect to the client principles) and institutional / system based (i.e. principles of fairness and objectivity, institutional self-regulation and integrity) factors. Thus, improvements and developments of the factors would lead to increase in public trust.
