NDR had set up a national final for the 2020 contest with several artists to choose the first German entry, "Stronger with You" performed by Susan Oseloff, which placed last out of twelve competing songs, scoring 66 points.

On 3 August 2021, Kika announced the top three candidates selected to proceed to the national final.

Each of the three finalists performed two candidate Junior Eurovision songs selected by them from three already produced songs, provided by composers signed to record companies, entitled "Gut so" (English: Good this way), "Hausboot" (English: Houseboat), and "Imagine Us".

The jury panel included Hannah from the broadcaster Kika, and two music experts consisting of artists Selina Mour [de] and Gabriel Kelly.

The second phase of the online voting took place during the live show and began right after the last performance and was open for 15 minutes.
