The Certification of Regional Investor Service Centres (COI) is a periodic process - every three years, the Polish Information and Foreign Investment Agency (PAIiIZ) assesses the standards of providing information and  support of investors in every province of Poland. The certification process is divided into three steps. The first one is the evaluation of managing the investment sites and other bases in the particular region. Then, a study visit is arranged to the region to evaluate the technical aspects of the investment service process. Next, the work of Regional Investor Service Centres is assessed. PAIiIZ experts check how local authorities present and promote their offer in English. This year Opolskie and Zachodniopomorskie got the highest scores. The second were Lubuskie, Dolnośląskie and Pomorskie, while Podkarpackie and Ślaskie were the third best.

Both the president of PAIiIZ – Tomasz Pisula and the deputy minister of foreign affairs - Jan Dziedziczak agreed, that the past year has been a good one for investment figures in Poland.
