First Phase: The Blind Auditions. In this phase, the three coaches will have their backs to the participants and will be guided solely by their voice. There are 93 young people, however, only 45 will get on stage. If the contestant's voice wins over a member of the jury, he will press a button that will turn his chair to see the participant. In this way, you will demonstrate that you want this contestant to be part of your team. If more than one coach presses the button, the participant will have the option to decide which of the three wants to be trained in this competition; but if a single trainer presses the button, the contestant goes to his team automatically. In case no one of the jury presses the button, it means that the participant has not been selected.

Second Phase: The Battles. In this stage, the coaches will be forced to reduce their equipment to a third. They must face three of their members who must sing in a "ring". Those who confront each other must demonstrate who has the best voice. In the end, each coach will make the decision to eliminate two of them, who will have to leave the competition. So that the coaches can make a decision, they are advised by other singers. Then they will choose two and the other three will sing the song they sang in the blind auditions, so that they choose one of those three and will join the other two for the live ones. In season 5, the steal from the adults' version of the show was implemented. Each coach has the opportunity to steal one young artist from other teams. In season 7, steals were raised to two per coach.

Third Phase: The Last Assault (Sing Off). Each contestant must defend their subject of blind auditions before the members of the jury and their advisors. Of each team will be only two contestants who will go to the grand final.

Fourth and final Phase: The Grand Final. This last phase of the program includes two parts: The semifinal and the final. The finalists will sing songs individually, as well as with their respective coaches, in addition to performances with guest artists. After the first elimination, only 3 contestants will fight to be finally: La Voz Kids (Spain).
