The ensemble believes that close collaboration with composers is vital to the process of interpreting modern music and therefore attempts to work with every composer whose music it plays. The players' commitment to educational work is exemplified by their masterclasses and workshops for young performers and composers all over the world. From 1982 to 1996 the quartet’s members were resident string tutors at the Darmstadt Summer Courses for New Music.
The Arditti Quartet’s extensive discography now features over 180 CDs. Forty-two discs have been released as part of the ensemble’s series on the French label Naïve Montaigne. The series presents numerous contemporary composer features as well as the first digital recordings of the complete Second Viennese School's string quartet music. Stockhausen’s Helicopter Quartet is to be found here. As well as many composer portraits recorded in their presence, the complete quartets of Luciano Berio were recorded shortly before his death. The quartet have recorded for more than 20 other labels and some of the latest releases on the Aeon label include the complete string quartets by Harvey, Dusapin, Birtwistle and Gerhard. 
Over the past 25 years, the ensemble has received many prizes for its work. They have won the Deutsche Schallplatten Preis several times and the Gramophone Award for the best recording of contemporary music in 1999 (Elliott Carter) and 2002 (Harrison Birtwistle). The prestigious Ernst von Siemens Music Prize was awarded to them in 1999 for "lifetime achievement" in music. The complete archive of the quartet is housed in the Sacher Stiftung in Basle, Switzerland.
