A consultation on which system should replace the current GCSEs studied by Island 14-16 year olds, has come out strongly in favour of the international version of the exams.
More than 800 people responded to the Department of Education's request for views on which direction the Isle of Man should take when GCSEs are reformed in England.
Initial findings show that 82% of respondents, the majority of them parents, would be happy to move to IGCSEs.
More than three quarters of submissions were opposed to the replacement qualification for 16-year olds being based solely on exams.
Other options outlined in the consultation were to adopt the GCSE replacement exams in England or to follow the Scottish system.
More than six in 10 responses came from parents, with a quarter from teachers.
There was wide consensus on whether qualifications should be controlled by a national government: almost 60% of respondents agreed they should be as politically independent of other governments as possible.
The IGCSE is owned by Cambridge University.
