Seventeen entries competed in the national final on 20 February 2018, which resulted in "Nova deca" performed by Sanja Ilić and Balkanika as the winner following the combination of votes from a five-member jury panel and a public televote.Performing during the show in position 3, "Nova deca" was announced among the top 10 entries of the second semi-final and therefore qualified to compete in the final on 12 May.The winning entry, "Ljubav je svuda" performed by Moje 3, failed to qualify Serbia to the final at the 2013 Eurovision Song Contest.The selection was held on 20 February 2018, hosted by Dragana Kosjerina, Kristina Radenković, Branko Veselinović and Aca Stojanović.The winner, "Nova deca" performed by Sanja Ilić and Balkanika, was decided by a combination of votes from a jury panel consisting of Vojislav Borisavljević (composer), Ivana Peters (singer-songwriter), Dušan Alagić (composer), Dejan Petrović (trumpeter) and Željko Vasić (singer), and the Serbian public via SMS voting.On 29 January 2018, a special allocation draw was held which placed each country into one of the two semi-finals, as well as which half of the show they would perform in.Each nation's jury consisted of five music industry professionals who are citizens of the country they represent, with their names published before the contest to ensure transparency.This jury judged each entry based on: vocal capacity; the stage performance; the song's composition and originality; and the overall impression by the act.In addition, no member of a national jury was permitted to be related in any way to any of the competing acts in such a way that they cannot vote impartially and independently.
