Venue

On 16 March 2017, it was announced that the Tbilisi Sports Palace would be the host venue for the contest.^[6] However, on 9 August 2017, the venue was changed to the 4,000-capacity Olympic Palace in Tbilisi which was considered more suitable for hosting the contest.^[7]

Officially opened on 13 July 2015 by Georgian Prime Minister, Irakli Garibashvili, the venue was built to host the 2015 European Youth Summer Olympic Festival. The complex features two halls that are capable of hosting several sporting events.^[8]

Visual design

The theme for the contest, Shine Bright, was unveiled on 12 May 2017 during a press conference prior to the 2017 Eurovision Song Contest in Kyiv. The emblem is a multi-coloured, stylized sun, representing a "burst" of expression; Jon Ola Sand explained that the theme reflected the goal of the Junior Eurovision Song Contest to give youth "a moment to shine and an opportunity to showcase their full potential as young artists".^[11]

Language

The original rules of the competition were changed, allowing up to 40% of each song to be in a language other than the national language of the representative's country, instead of 25% as in previous years.^[12] This allowed countries, such as the winner, Russia, to have both a verse and a chorus in English, rather than just a chorus.

Hosts

On 3 October 2017, it was announced that Helen Kalandadze and Lizi Japaridze would host the contest. Japaridze is the third person under the age of sixteen to ever host the Junior Eurovision Song Contest, after Ioana Ivan in 2006 and Dmytro Borodin in 2009, and also the first former participant to host an edition of the contest. Japaridze previously represented Georgia in the Junior Eurovision Song Contest 2014, where she placed eleventh with the song "Happy Day". Kalandadze is a television presenter and singer, who previously was a backing singer for Georgia's 2010 Eurovision entry "Shine" by Sofia Nizharadze.^[13]

Voting

The results were determined by national juries and an online audience vote. Every country used a national jury that consisted of three music industry professionals and two kids aged between 10 and 15 who were citizens of the country they represent. The first phase of the online voting started on 24 November 2017 when a recap of all the rehearsal performances were shown on the official website before the viewers could vote. Following this recap, voters had the option to watch longer one-minute clips from each participant's rehearsal. This first round of voting ended on 26 November at 15:59 CET. The second phase of the online voting took place during the live show and started after the last performance and was open for 15 minutes. International viewers could vote for a minimum of three countries and a maximum of five. For the first time, viewers could also vote for their own country's song.^[14]

The number of points were determined by the percentage of votes received. The public vote counted for 50% of the final result, while the other 50% came from the professional juries.^[15]

Trophy

The trophy was designed by Kjell Engman of the Swedish glass company Kosta Boda. Engman also designed the adult contest trophy. From this year, the design of the trophy was unified and awarded to the subsequent winners. The main trophy was a glass microphone with colored lines inside the upper part, which symbolize the flow of sound.^[16]
