More than 800 education specialists from more than 70 countries attended the congress.
The four-day event was held in Scotland for the first time in its 30-year history and attracted some of the world's leading authorities on special needs, including Professor Kaoru Yamaguchi of Seisa University in Japan, Mel Ainscow, professor of education at Manchester University, and Dr Mary Ruth Coleman from the University of North Carolina.
Education ministers from Botswana and Denmark also attended the event, where there were more than 350 talks covering issues ranging from school discipline to visual arts provision for additional support needs, the early identification of dyslexia in bilingual pupils and the loneliness of special education teachers.
Isobel Calder, of Strathclyde University's education faculty, who was the conference chair, said: "It has helped people to make international connections which will forward the cause of global inclusion and that will result in children across the world doing better."
One delegate who had been to every ISEC since 1975 said this was the best ever.
