In 2013, SORT has also renewed the certificate of excellence given in 2011 by Fundación Española para la Ciencia y la Tecnología which guarantees publishing and scientific quality for the next three years. SORT represents the third series of the Quaderns d'Estadística i Investigació Operativa (Qüestiió), published by Idescat between 1992 and 2002, which in turn followed from the first series "Quaderns d'Estadística, Sistemas, Informàtica i Investigació Operativa" (1977–1992). The three series of Qüestiió have their origin in the "Cuadernos de Estadística Aplicada e Investigación Operativa", published by the Universitat Politècnica de Catalunya until 1977.

The Impact Factor is established by dividing the number of times articles published in 2013 and 2014 were cited in 2015, based on a search of the Science Citation Index Database, by the number of articles published in the previous two years (2013 and 2014).
