For two decades, American Digital University (ADU) has been publishing quality courses related to the maritime industry. Its journey began with the realisation that there was a real problem with access in the sector, so it set about addressing this through the creation of more accessible instructional and learning opportunities for students interested in entering the maritime industry.

Together with industry and educational leaders, ADU has worked to redefine maritime learning and training by transforming brick-and-mortar classes into effective web-based channels. In India, through a government sponsored programme, ADU has become the de facto online training provider for the national maritime community and works extensively with the regional Work Force Development Boards to provide skill-based training.

ADU also specialises in e-learning consultancy and e-learning content development for various higher education institutions. Alongside its highly successful maritime course, it also publishes courses in mathematics and science.Read the full story of how ADU became industry leaders in maritime education on the Alison Blog.
