Productions staged in recent years have included Les Misérables, Arthur Miller's The Crucible, Oliver!,"Phantom Of The Opera", Oklahoma!, "Macbeth", and “Hairspray” with “Fiddler on the Roof” being performed in December 2018 
All pupils must take part in two periods of Games each week. Rugby is the main winter sports for boys with cricket and other types of athletics being practiced in the spring season. Hockey is the main sport for girls at the school. Football and Orienteering are also available during the two Games periods. Dalriada football has risen in popularity through the success of the Under 14 team, winning the league twice in a row.
The senior debating society, Arguendo, is where pupils in Year 11 and above debate. Since its revival in 2008 the society has become popular, with Dalriada entering teams into the annual Debating Matters competition and the Denny all-Ireland Debating Competition. In 2009 a team of six won the Debating Matters Northern Ireland competition held in Coleraine University.
In 2009/2010 Arguendo entered the Northern Ireland Debating competition for the first time. The upper sixth team were awarded Team of the Competition at the finals in Stormont after being defeated in the Quarter Finals.
In 2010/2011, the Society entered the UK Wide Debating Matter Championship. A team of six debaters won the Derry Qualifying Heat to make it through the Northern Ireland and Scotland final in Edinburgh, where they triumphed over schools from across the two countries. This allowed them to then qualify for the National Final held at the Royal Society of Medicine where they were defeated in a debate on the Banning of the Burqa.
Dalriada also competes in the annual Bar Mock Trial Competition. The team prepares mock legal cases for the regional finals each year in the Royal Courts of Justice in Belfast, winning this competition three times. After winning the prestigious National Championships in London in 2016 for the first time , Dalriada pupils went on to compete in the Empire Mock Trial World Championships in New York for the third time . At this event Dalriada had the experience of litigating in a different jurisdiction, and a student received an award for Outstanding Witness .
