The International Schools’ Athletic Championships (ISAC) held on 23rd February to 25th February 2018 at Diyagama Mahinda Rajapaksa Stadium was a huge success. It was the biggest national flagship sporting event in the school calendar of 23 International Schools affiliated with The International Schools of Sri Lanka (TISSL). In 2004, Lyceum International School, Nugegoda, took over the responsibility of organizing this prestigious event from Gateway College, who had organized it for 3 years since its inception in 2001.

In 2015, Lyceum took over the reigns from Gateway College once again, to serve as the official organizer for the next 3 consecutive years - 2016, 2017 and 2018.
