* ProductionPosse: Dan Schneider has a tendency to re-use actors that he likes.
** Amanda Bynes has been [[Series/AllThat Am]][[TheAmandaShow an]][[TheDanza da]] and [[WhatILikeAboutYou Holly Tyler]]
** Victoria Justice has been [[{{Zoey101}} Lola Martinez]], [[Series/ICarly Shelby Marx]], and [[Series/{{Victorious}} Tori Vega]]
** Miranda Cosgrove has been [[Series/DrakeAndJosh Megan Parker]], [[{{Zoey101}} Paige Howard]], and [[ICarly Carly Shay]]
** Jerry Trainor has been [[Series/DrakeAndJosh Crazy Steve]] and [[Series/ICarly Spencer Shay]]
** Creator/DrakeBell and Josh Peck have been in TheAmandaShow and Series/DrakeAndJosh.
** Creator/DaniellaMonet has been [[{{Zoey101}} Rebecca Martin]], [[NoNameGiven popular]] [[Series/ICarly girl]], and [[Series/{{Victorious}} Trina Vega]]
** Creator/JennetteMcCurdy was [[{{Zoey101}} Trisha Kirby]] and [[Series/ICarly Sam Puckett]] and gained a lead role in Dan's next show.
** Allison Scagliotti was [[Series/DrakeAndJosh Mindy]] and [[{{Zoey101}} the girl who stole Zoey's backpack idea]].
** He also has a stable of writers and directors, some of whom have been with him since the beginning.
** He has several 'chains' of shows that develop from a previous one featuring the same actors in new roles. They start with Series/AllThat:
*** Series/AllThat -> KenanAndKel
*** Series/AllThat -> TheAmandaShow -> WhatILikeAboutYou (AmandaBynes).
*** Series/AllThat -> Zoey101 -> Series/{{Victorious}} (VictoriaJustice) -> The Sam and Cat SpinOff
*** Series/AllThat -> TheAmandaShow -> Series/DrakeAndJosh -> Series/ICarly -> The Sam and Cat SpinOff ''AND'' the supposed Gibby SpinOff. (Drake and Josh, then Creator/MirandaCosgrove and Jerry Trainor, Creator/NathanKress played a minor role in DrakeAndJosh that was cut because he signed to be on ICarly, then Creator/JennetteMcCurdy and Noah Munck).
* PromotedFanboy: Before suddenly becoming an actor for ''Head Of The Class'', he was a simple computer geek (during a time when Amiga and Commodore ruled the home computer market, no less).
* RecycledScript: Several cases since Series/DrakeAndJosh where an episode has been a direct lift of an earlier episode in another series.
** Also has a massive tendency to repeat jokes. One example being the "three legged cat" joke.
** Dan made DrakeAndJosh an entire series about main characters being pranked by a young kid, and he's made half a dozen episodes of iCarly on the same premise.
** He copies a lot of short one-line jokes or physical comedy bits from {{Friends}}, and before you think it's a coincidence, Dan loves Friends and knows it like the back of his hand, as well as knowing David Schwimmer:
*** The entire Spencer is dead plot is completely stolen from a plot involving Ross.
*** Sam teaching Spencer how to lie, ripped off from Phoebe teaching Joey how to lie.
*** A physical joke where Spencer is sad and lies down on the kitchen table, stolen.
*** Melanie the twin plot. Identical to a Phoebe plot-line.
*** Chandler remarks about how travel sized items make him feel like a giant. Freddie says the exact same line.
* TeasingCreator: As stated, Dan gets a lot of kicks of teasing Shippers. Unfortunately [[FanDumb this ended up awakening the nastier side of his fanbase.]] He started in earnest after the ''iKiss'' episode of iCarly awakened him to the idea of {{Shipping}} and the fandom of shipping, and continued it through to the end of iCarly, through Victorious and now SamAndCat. His teases include:
** Constantly posting still pictures or movies from the set implying romantic developments. He's done this with Sam/Freddie & Carly/Freddie on iCarly, Beck/Tori, Cat/Robbie, Jade/Beck ''and'' '''Jade/Tori''' from Victorious.
** He has teased Sam/Freddie & Cat/Robbie shippers while making SamAndCat, with the idea of the male parts of those pairings showing up on the new show. And, of course, he's turning up the teasing on [[LesYay Sam and Cat]] ''themselves''.
** His blatant revisionism via his post-episode 'fun facts', where he gives loads of attention in the blog posts to the pairing that ''wasn't'' just explored. Downplaying the romantic events in the episode or trying to reverse and muddy the waters constantly.
* ThrowItIn: If a blooper is funny enough, he'll throw it in the final cut of the show.
* WhatCouldHaveBeen: Dan has implied that the Disney Channel stole an idea he pitched years earlier for a show that eventually became SonnyWithAChance. Had Disney picked up his show it's quite possible he'd have never worked for Nick again. Depending on exactly when he pitched it could have meant that Zoey101, DrakeAndJosh, ICarly, Victorious as well as SamAndCat either never got made or got made in Disney form. Considering those shows formed the core of Nick's live action for the better part of a decade it would have changed things immensely. As one random example, if DrakeAndJosh ended up on Disney, it might have been MirandaCosgrove who became HannahMontana and not Miley Cyrus.
** Then again Dan has stated in his own blog that there's "nothing preventing him" from working with Disney and implied that it ''could'' happen in the future for whatever reason (the link is even in the main article's Tropes page). This implies that at the very least he feels no bad blood over the situation if it was indeed true. At the very least it somewhat clouds the issue.
