Delta Tests (or Delta Test) are computer-based tests designed to assess the knowledge and skills of seafarers in accordance with international safety and professional training standards, particularly under the requirements of the STCW Convention (International Convention on Standards of Training, Certification, and Watchkeeping for Seafarers).
These tests are used as a tool to verify the qualifications and compliance of seafarers with professional standards, which is important for working on international vessels.
Examples of topics covered by the tests include navigation, ship handling, mechanics, electrical engineering, ship management, and onboard safety.
Questions may address both theoretical knowledge and practical skills that seafarers need to demonstrate in real-world conditions.
