For the evaluation of equality data and measures, there is no clear definition of the term 'screening'. Screenings are intended to identify actions likely to have an impact on equal opportunities and/or the establishment of good relations. It is therefore one of the methods that enables public authorities and/or companies to meet their legal obligations and to mainstream equal opportunities and good relations in their decisions and policies.

The first step of a screening involves the regular evaluation of personal data and customer feedback. As far as possible, a screening should be carried out by all relevant employees and decision-makers. The focus should be on the possible side effects of the measures to be taken and should be carefully examined as to whether these measures affect or enhance the equality goals of the company and/or the authority - Northern Ireland Equality Commission, Guide for Public Authorities, page 51-53.
