Channel Hop: The show went from PBS Kids (as part of a Sunday morning block "Bookworm Bunch", which featured an array of Nelvana cartoons based on books), where it completely aired its two seasons, to a weekday morning block, "Ready Set Learn" on TLC and Discovery Family (when they were Discovery Kids). Reruns then began airing on Qubo in 2013.
Timothy, Charles, Fritz, and Claude are all voiced by females in the French dub.
Dub Name Change: In France the show and the original book version of "Timothy Goes To School" is called Timothée va à l'école.
Timothy is called Timothée in France.
The series is called 티모시는 학교에갑니다 (timosi neun haggyoe gabnida, or "Timothy's Kindergarten Days") in Korean.
Edited for Syndication: When rerun on Qubo, scenes were sometimes cut for time (justified, as it was intended to air on non-commercial stations without ad breaks).
Keep Circulating the Tapes: Some DVD releases are difficult to obtain, but installments can be found online. For a while it wasn't airing on TV. It does now air on Qubo, though that can be hard to get. However, the full series is available on YouTube, although the episodes uploaded in Treehouse's official channel are blocked in some countries.
Recycled Script: The episode "Mama Don't Go" where it's Juanita's first visit to Hilltop School with her mother after moving was adapted as a Yoko & Friends book of the same name. Yoko takes the place of Juanita, but basically is the same plot as the episode.
Recursive Canon: Yoko's 1998 debut was supposedly her first day at school as well along with the 2008 book "Yoko Writes Her Name"
Relationship Voice Actor: This isn't the first time Lisa Yamanaka (Yoko) and Alyson Court (Nora) were both voicing characters in the same production. Before the show started, both were in Resident Evil 2- Alyson was Claire Redfield while Lisa was Sherry Birkin.
Urban Legend of Zelda: According to some sources, there appears to be an episode titled "The Butterfly Away", which is one of the first things that appears as an add-on when you start to google the show's title. However, given that the only source claims the episode premiered in August 2014, it's completely false. The plot for this fictional episode involves Timothy and friends watching the migration of Monarch butterflies.
