The Executive Supervisor for the Junior Eurovision Song Contest, Vladislav Yakovlev, praised the Italian broadcaster RAI for their time looking into the possibilities of hosting, even though they made their debut appearance in 2014, and further explained how the EBU were in a lucky position to have received bids from two countries.

[8] Two venues in Sofia – Hall 1 of the National Palace of Culture and Arena Armeets – were considered and visited by EBU officials, including executive supervisor Vladislav Yakovlev, in February 2015.

[10] Prior to the event, a digital compilation album featuring all the songs from the 2015 contest was put together by the European Broadcasting Union and released by Universal Music Group on 13 November 2015.

The slogan was selected to signify how the Junior Eurovision Song Contest endeavours to find new melodies, explore new people and create links between individuals.

On 23 June 2015, the EBU in conjunction with the host broadcaster BNT, presented the official logo for the 2015 edition, during the Steering Group meeting held in Sofia.

[16] Viara Ankova, the Director General of the host broadcaster explained that the logo's concept was inspired behind the idea of a seeded head of a dandelion being blown, "something that everyone has done as a child".

In addition, the running order draw and opening ceremonies were hosted by Bulgarian singer Joanna Dragneva, who had also previously represented Bulgaria at the Eurovision Song Contest in 2008 as part of Deep Zone Project.

[20] The opening of the show featured Krisia Todorova, Bulgaria's 2014 representative alongside Hasan & Ibrahim, performed a short reworked sequence of the theme song "#Discover".

Vincenzo Cantiello closed the interval and performed his winning song "Tu primo grande amore".

[23] Destiny Chukunyere who represented Malta with the song "Not My Soul", was declared the winner after all the votes had been cast from all of the seventeen participating countries and the kids' jury.

For a country to be eligible for potential participation in the Junior Eurovision Song Contest, it needs to be an active member of the European Broadcasting Union (EBU).

[29] In August 2014, executive supervisor Vladislav Yakovlev said that they are working on finding a way to allow commercial networks to participate in the contest, although they are not EBU members.

The online broadcasts featured commentary in English by junioreurovision.tv editor Luke Fisher and 2011 Bulgarian Junior Eurovision Song Contest entrant Ivan Ivanov.
