The same voting system that was introduced in the 2017 edition will be used, where the results will be determined by 50% online voting and 50% jury voting. Every country has a national jury that consists of three music industry professionals and two children aged between 10 and 15 who are citizens of the country they represent. The rankings of those jurors are combined to make an overall top ten.[1]

The online voting consists of two phases. The first phase of the online voting will begin on 15 November 2024 when a recap of all the rehearsal performances is shown on the contest's website Junioreurovision.tv before the viewers can vote. After this, voters will also have the option to watch longer one-minute clips from each participant's rehearsal. This first round of voting will end on 16 November at 17:59 CET. The second phase of the online voting will take place during the live show and begin right after the last performance and will be open for 15 minutes. International viewers will be able vote for three songs.[2] They will also be able to vote for their own country's song. These votes will then be turned into points which will be determined by the percentage of votes received. For example, if a song receives 10% of the votes, it will receive 10% of the available points.
