The NIK is more positively evaluated by men (50% positive responses) than women (42 % positive responses). The NIK's work is more appreciated by respondents between the ages 25 and 34 (49% positive responses) and 45 and 54 (49% positive responses). As much as 66% of respondents with higher education see NIK's activities as favourable (11% more than in 2009). 65% of respondents with managerial positions (in private or public sectors) evaluate the NIK's activities favourably (8% more than in 2009). The NIK is also valued by those working in public institutions (59% favourable responses – 6% more than in 2009). The increase in positive evaluations of the NIK is parallel to respondents' income and education.

Regardless their political stand, wether it is the left, the centre or the right, respondents' evaluations were similar (respectively 53, 53, 52%). Other public institutions have noted considerable decrease in positive evaluations in recent years. The Polish Constitutional Tribunal (Trybunał Konstytucyjny) is positively evaluated by 43% of Poles (5% less than in March 2009), the Polish Courts receives positive reviews from 32% of respondents (8% less than is 2009). Also there has been a decrease of favourable opinions of the Polish Prosecution – from 38% in March 2009 to 32% as present. Poles' evaluation of the Congress has been very critical. Only 23% of Poles say that the Congress works well. 61% of respondents evaluate the work of the Congress poorly.
Poles' most highly regarded are traditionally: firemen, police, the military and the Catholic Church. Large percentage of positive evaluations 60% got the President of Poland.
Not as far as in 1998 the NIK was highly evaluated by 60% of Poles. In May 2007 favourable reviews reached only up to 40%.
