Following two highly successful seasons, SBS6 has commissioned a third season of Talpa Studios’ The Know-It-All: a remarkable milestone for a format that only launched a year ago. The rapid renewal for a third season underlines the format’s momentum and audience connection.

Since its debut, the feel-good celebrity quiz show has delivered strong results for SBS6. Season 1 averaged a 3.19% audience density (25-59, live+6), while season 2 achieved a 3.10% audience density. Both seasons performed above the channel benchmark, making The Know-It-All one of SBS6’s strongest-performing entertainment titles and the leading new quiz format launched by the broadcaster in 2025 and 2026.

The renewal for a third season is a testament to the show’s winning formula: familiar celebrities, entertaining gameplay, genuine humour and suspenseful elimination mechanics that keep viewers coming back for more.

In The Know-It-All, 22 celebrities head back to school for a fun, light-hearted and competitive quiz adventure. Set in a nostalgic elementary school complete with wooden desks, chalkboards and a strict-but-fair head teacher, contestants face a mix of clever word games, visual puzzles and larger-than-life challenges. As the competition unfolds, points are earned, rankings shift and celebrities are gradually eliminated. The two lowest scorers leave each episode, until only eight remain for the final stage. From there, it’s one game at a time, one dropout at a time, until one celebrity is crowned The Class Champion.

The Know-It-All is a format created and distributed by Talpa Studios.
