English has established itself as a major language in the maritime world, so the Center for lifelong learning Bozic, as an approved Marlins Test Center, offers  preparation and carrying out of English language tests for seafarers. The  ISF Marlins Test  enables the employers to gain an insight and assess the ability of seafarers to communicate in English, regardless of their nationality, as it has become a  need that has received additional emphasis due to the ISM Code and amendments to the STCW Convention. The ISF Marlins English Language Test has been officially recognized by the UK Maritime and Coastguard Agency as certificate of English language proficiency for the successful application of STCW. The test is applicable to all officers and  crew members (including other personnel).
