A growing market for native English speaking teachers (not only ESL teachers):

There are now almost 8,000 courses being taught in English by leading universities in non-English speaking countries, according to a project mapping their expansion.

The rise of universities teaching in English, rather than their own local language, has become a global phenomenon.

These are not only appealing to the world's five million international students who travel abroad, they are also being chosen by students staying in their own countries who prefer to study in English rather than their own language.

The research is from a Dutch-based organisation, StudyPortals, which has a database of information on 100,000 bachelor and masters' degrees at over 2,100 universities around the world.

This is more than a European trend. Of the 112 top universities identified in China, 45 offer one or more English-language degrees, as do 20 in Taiwan, 11 in Japan and six in Thailand.

According to the ACA's report, about 45% of those on English-taught university programmes in mainland Europe were studying in their own countries.

The rising numbers of students studying abroad could drive this trend even further.
