A common problem in fiction is to get a group of people with differing backgrounds and contrasting personalities together. When writing characters who are children or teenagers, there's a simple solution: Have the school system force them together in some way. They could be placed in the same class or have to do a group project. Perhaps they could all have detention at the same time. Maybe they bond over their mutual hatred of the school system or enjoyment of school. This trope doesn't work all the time — for instance, children from rich families might be sent to private schools and won't have the same opportunity to interact with poorer kids. Kids who grow up in different neighborhoods may go to different schools. However, in general, schools can be used as a way to get characters from different backgrounds to form friendships. If these bonds last into adulthood, this becomes Everyone Went to School Together.
Super-Trope to The Breakfast Plot. May lead to a Bully Turned Buddy scenario. See also Odd Friendship, Rag Tag Bunch Of Misfits, and Interclass Friendship. Compare with Recruit Teenagers with Attitude, Bully and Wimp Pairing, and Absurdly Divided School.
Examples:
- In Cesare - Il Creatore che ha distrutto, Cesare's father Rodrigo has him transfer to the University of Pisa as part of his election campaign — Cesare is to influence Archbishop Raffaele Riario to come to his side, and also to strengthen his family's ties with the Medici by helping Lorenzo de'Medici's son Giovanni graduate before the pope dies, so that the pope's promise to make Giovanni a cardinal on the condition of his graduating will be fulfilled, and also so that Giovanni can take his place as a cardinal in time to vote for Rodrigo. Most of the Florentine organization is also trying to use this as an opportunity to suck up to Giovanni in hopes of future advancement.
- Subverted in Digimon Adventure 02, where adversaries Davis and Ken, who keep at a distance when in the Digital World and live some distance away from each other in different parts of Tokyo, end up meeting face-to-face because of their respective commitments the soccer clubs they both signed up for. It leads to Ken's identity as the Digimon Emperor being revealed at the end of the same episode.
- Miko and Onodera from Kaguya-sama: Love Is War end up becoming friends due to their time together on the Culture Festival committee (Onodera had joined voluntarily while Miko was there as a representative of the Student Council). While the two were already in the same class, it's clear that they never would have interacted otherwise due to just how different their personalities and social circles were.
- Keep Your Hands Off Eizouken! establishes this as being how Asakusa and Kanamori first met. Both of them lacked a partner for a two-person activity in middle school gym class, and the coach, against the Shrinking Violet Asakusa's wishes, paired her and the stonefaced, thuggish Kanamori together. Despite the rough meeting, the two eventually managed to form an Odd Friendship, with Asakusa describing Kanamori as her "comrade" in a conversation with Mizusaki.
- Leave for Mendeleiev: After Marinette transfers to another class, one of the ways Chloé tries to regain access to her favorite target is by convincing Miss Bustier that she needs a tutor. Bustier then tries pressuring and guilt-tripping Marinette into taking up the role; while it's ultimately Averted by Marinette and others refusing to let her be forced into anything, it still speaks volumes to Bustier's naivete and sense of entitlement.
- The usage of this in My Hero Academia is occasionally Deconstructed and called out as a Fandom-Specific Plotline. Specifically, several stories criticize Aizawa and other teachers forcing Izuku to work with his Barbaric Bully Katsuki:
- In Snap Before You Break, Izuku outright refuses to partner with Katsuki for their Final Exam, which turns into an extensive "The Reason You Suck" Speech to Aizawa for being an Apathetic Teacher:
Izuku: What the actual fuck is wrong with you?! Do you have the reading comprehension of a two-year-old?! You should be able to figure out, Mr. #1 Underground Hero, that Bakugou was, is, and has always been my bully, but you keep putting us together! What am I supposed to learn from teaming with Bakugou?
Aizawa: You're supposed to learn to work with people you don't like.
Izuku: I CAN WORK WITH HIM, YOU FUCKING LUNATIC! HE'S THE ONE WHO CAN'T WORK WITH ME! Now I ask again. What. Am. I. Supposed. To. Learn? How to take abuse and shut up because it's better for my abuser? How to smile and nod even when an asshole is burning me? (shows off a burn scar on his shoulder in the shape of a handprint) I fucking know very well how to do that! - Yesterday Upon The Stair turns the Final Exam into a deep personal regret for both Aizawa and Toshinori when they realize that Katsuki beat the shit out of Izuku for the high crime of trying to work with him.
- In Snap Before You Break, Izuku outright refuses to partner with Katsuki for their Final Exam, which turns into an extensive "The Reason You Suck" Speech to Aizawa for being an Apathetic Teacher:
- Off To The Races: While Fukuda and Suzuki are both espers, the only other thing they have in common is that they attended the same class in middle school. Their entire thirty-year friendship is built off of those two factors.
- The Breakfast Club gets together a jock, a geek, the rich girl, a strange goth, and the troublemaker — who had never interacted (and by their own admission, would not, save for perhaps making fun of each other) outside of Detention.
- Only two of the main characters in Jumanji: Welcome to the Jungle already knew each other. They all meet serving detention clearing the school basement, where they find the game console that kicks off the plot.
- The Anderssons: In "Spränga gränser", Cecilia is the de facto leader of a group of five very different girls in school. Cecilia is a Fiery Redhead and the one who comes up with all the new ideas. Bibbi is the pretty blonde, who seems to know more about men than the others. Aina is a Straw Nihilist, who likes to read Sartre and worry about a new war maybe starting. Gunilla is the shy and very religious Preacher's Kid. Helene is the one girl in the group with the most nondescript personality, but she got a leg damaged from polio and looks like Audrey Hepburn. Also, Cecilia and Bibbi have working class parents and the other three have middle class parents.
- In Are You There God? It's Me, Margaret., Margaret (after her class acts out) is made to sit between to Class Clown Freddy Barnett and "bad girl" Laura Danker. She later has to do a group project with Laura, Philip Leroy, and Norman Fishbein, which means sitting together and talking; Margaret, who has been believing all the rumors about Laura Danker, is upset at this. She also is irritated that Philip doesn't help at all, her Abhorrent Admirer Norman reads moving his lips, and the project is on Belgium, which she thinks is a boring country. She eventually takes her frustrations out on Laura while they're at the library, and Laura calls her out on it.
- The five main characters of Bad News Ballet all meet during ballet auditions for the local dance academy's performance of The Nutcracker, and all of them but Mary Bubnik have taken some form of informal ballet class ballet prior to the auditions. They remain together afterwards in the class, in part for each other and in part because they can't let their rivals the Bunheads think they're quitters.
- The Chronicles of Narnia: While C. S. Lewis goes into Lemony Narrator mode to indicate his disapproval of the "mixed" school Experiment House in The Silver Chair, the fact remains Eustace and Jill would never have met if they hadn't both been sent there.
- In Discworld, the loosely organized training coven for teenage Witches brings together girls of widely differing outlooks and personalities, from the Alpha Bitch Annagramma Hawkin to the quiet and reflective Tiffany Aching.
- Harry Potter: Students who go to Hogwarts are sorted into Houses. As this sorting is based on the students' traits, this can lead to people with similar personalities and even similar backgrounds being grouped together. However, there are exceptions. For instance, Parvati and Padma Patil are identical twins, but in the book series, Parvati ended up in Gryffindor and Padma in Ravenclaw. Slytherin is typically the alma mater for Pure-Blood supremacists, but does admit half-blooded and muggle born students. In fact, the most infamous member of this house was half-blooded himself.
- My Youth Romantic Comedy Is Wrong, as I Expected reunites three students — Hachiman Hikigaya, Yukino Yukinoshita and Yui Yuigahama (a lesser member of the Girl Posse) — to work together as a team in the Service Club. They eventually become Fire-Forged Friends with the time and, ultimately, an unwanted Love Triangle.
- The three main characters of The Poison Apples have hardly anything in common besides having Wicked Stepmothers: Alice is a Lonely Rich Kid from Brooklyn Heights, Reena is a Lovable Alpha Bitch from Beverly Hills and Molly is a nerd from the middle of nowhere. What brings them together? Boarding School.
- Princesses of the Pizza Parlor: The titular party comes about because they were stuck at school and left together, as the only students there.
- A Song of Ice and Fire: While Westeros doesn't have an organized school system, it does have the Citadel that is responsible for training Maesters. As the Citadel is an egalitarian institution, at least on paper, the Lowborn trainees are allowed to study alongside noble trainees. Once their training is done, the Citadel sends Maesters across Westeros to serve the nobility. This placement is supposed to be random and impartial. This is why an Ironborn will serve in the Reach, or a Lannister will serve in the North.
- Arrow. Used to handwave how the Lance daughters know the billionaire Queens and Merlyns. Though you'd think the latter would go to a more exclusive private school.
- Buffy the Vampire Slayer: The first season, our titular heroine meets all of the main cast, including her Watcher, when she transfers into dear old Sunnydale High. Except this one cute-but-mysterious guy she only sees at night...
- Community: The main characters come together to form a study group in order to get through Spanish. Due to their differing personalities, it's unlikely they would have become friends otherwise. For instance, while Annie and Troy went to the same high school, the two were in separate social groups (Annie being more focused on studying and Troy being a jock).
- Glee: When he takes over as head of the Glee club, Mr. Schuester tries to recruit popular kids, thinking it will encourage more people to join. He's initially unsuccessful as they think the Glee club is uncool. He ends up planting weed on Finn, the football team's quarterback. When he confronts Finn, he offers to not turn him in if he joins the Glee club.
- Mostly averted on Head of the Class, since the show revolves around a class of gifted students who largely have a fair bit in common. Played straight with a few examples, however, such as later addition T.J., who had a reputation for being a troublemaker until it was realized that she was just bored and needed the extra push that the gifted class could give her.
- Malcolm in the Middle:
- In one episode, Malcolm is literally forced to join the Booster club by Mr. Herkable (he oversees the booster club and gets a bonus if another student joins) who threatens to withhold Malcolm's letter of recommendation. Malcolm doesn't get along with the other members of the booster club, finding them too cheery and thinking their ideas to raise money are stupid. When he tries to leave, Mr. Herkable uses Reverse Psychology to get Malcolm to not only stay, but to put more effort into raising money.
- Another episode had the Krelboynes (gifted class) split up after an unauthorized experiment resulted in the Krelboyne room needing to be decontaminated. All of the Krelboynes end up joining separate cliques and bonding with different students when they're dispersed among the general student body; one falls in with the Goths after he quotes from Dante's Inferno, another one joins the jocks after removing a splinter from a jock's finger during a woodshop class, Stevie (who's in a wheelchair) joins the skater/BMX clique, and so on.
- Power Rangers: Dino Thunder starts with Conner, Ethan, and Kira getting stuck in detention. And frankly, the teacher Dr. Oliver is as stuck as they are since he had other plans that afternoon. So he brings the students along on his errand, and the three end up stumbling across some Power Crystals...
- Victorious: In one episode, the normally hostile Jade and Tori must portray a couple in a School Play. Their teacher doesn't find their onscreen chemistry convincing. He suggests the two go on a playdate together in order for them to build a stronger relationship.
- Played with in how SCANDAL started. The girls were in differing grades at their music school Caless when the call was made by the school asking for volunteers to create a rock band. The inital make-up of the band was Haruna, Tomomi and Mami. Days after the first three members, Rina was accepted and the band would eventually be named SCANDAL.
- Transhuman Space: The supplement Personnel Files 5 offers an example player-character group built round this trope. The English language school in the free city of Königsberg-Kaliningrad is small enough that a small group of teens of somewhat varying ages and backgrounds are obliged to hang out together, potentially pushing them into Kid Detective and similar plots; they include an apparent fashion victim who's actually fascinated by the theory of pop culture, a photography geek, a policeman's son/wannabe detective, a nervous slightly younger kid with an excellent robot dog sidekick, and a slightly arrogant leader type.
- Cesare - Il Creatore che ha distrutto has teenagers from powerful families of all of Italy's city-states, plus further afield, from France, Spain, and the like. The title character is the leader of Spain's student organization, and his group constantly comes up against the French students. The Florentine students end up in the middle of their fights. Cesare was sent to the school to befriend the head of the Florentine association, Giovanni de'Medici, to keep their families allied.
- In Wicked, bookish Elphaba was supposed to have her disabled sister, Nessarose, as her college roommate so that she could take care of her. She was placed with preppy blonde G(a)linda instead. They start off hating each other, but gradually become friends.
- In Deltarune, the protagonists, Kris and Susie, are put together in a group for a project. The story starts after they are both sent to retrieve chalk.
- Possible in Fire Emblem: Three Houses. The player can assign two students to group projects, where they can gain support points. Since the primary way of earning support points is making units fight alongside each other, group projects are useful for units who wouldn't normally fight together (such as a flier and an armored unit). However, characters who can't support each other won't gain any support points.
- In Growing Up, you first meet Kato in high school when paired up for schoolwork, but he insists on doing it by himself. From there, you have to help him balance his studies and gaming life.
- This forms the set-up of The Legend of Heroes: Trails of Cold Steel, where Class VII is an attempt to integrate students from various social classes, ranging from varying levels of nobility, middle class (including ones from wealthy backgrounds) and even war orphans and foreigners as part of the prince's plan to solve the class division that plagues the nation. While they naturally start off on rocky footing, through their various adventures they forge an unbreakable bond and consider each other as close as family.
- The trope is invoked in Danganronpa. Most of the killing games involve classes of students being forced to kill each other within a school setting.
- In Danganronpa V3: Killing Harmony, this is heavily exploited by the mastermind. None of the students knew each other prior to waking up in the school and all have drastically different personalities and backgrounds. Nonetheless, they form relationships with each other during their stay. After The Reveal, it turns out the characters were originally fans who auditioned to be on the killing game reality show Danganronpa, and had their personalities and memories fabricated to satisfy the audience.
- Summer school forces the main cast of Double Homework together. How could a traumatized world-class athlete, his Extreme Doormat sister, his rightfully resentful ex-girlfriend, a convicted juvenile delinquent and closet fantasy nerd, a wannabe popular girl who used to be a member of the convict’s gang, and an incognito princess with a love of gaming all become close friends? Put them in a weird summer school class together as part of a sex experiment.
- Galaxy Angel: According to Milfeulle, she and Ranpha met in the space academy and have been friends since then. For Ranpha it was more that she tried to compete with Milfie only to end up falling behind due to the latter's luck. Milfie had no idea Ranpha saw her as her rival at all.
- This happens in RWBY, where Hunter teams are essentially formed at random and spend their entire school career together. Weiss never would have had anything to do with Ruby or Blake if she had any choice. In fact, during their introductory trial run, Weiss actually tried to walk away from Ruby, but seeing that her only other option was Jaune, she reluctantly joined Ruby.
- The people who make up the Extreme Ghostbusters team were the four students (a mechanical genius, a wheelchair-bound Lovable Jock, a slacker, and a Gloomy Goth) who signed up for Egon's class at community college and were pressed into service when a supernatural crisis occurred. Despite the initial friction due to their different backgrounds, they soon became an effective team of 'busters.
- Played with in My Little Pony: Friendship Is Magic with Gallus, Ocellus, Sandbar, Silverstream, Smolder, and Yona. They met at the School of Friendship, but then it was closed indefinitely by the EEA. It was them hanging out outside of school and becoming friends on their own that convinced Twilight Sparkle to say Screw the Rules, I Make Them! and reopen the school, thus inverting the trope.
- School is what brought the group together in Recess; otherwise, a group consisting of a nerd, a tomboy, a jock, an artist, a schemer with a conscience, and the new kid would probably have never formed. In addition, there have been some episodes involving one of the group being transferred to another school, with the others being concerned that this would break up the group.
- The Simpsons: Despite being brother and sister, Bart and Lisa typically don't hang out at school due to their age difference. This changes in "Bart vs. Lisa vs. the Third Grade", where the students of Springfield Elementary must take a standardized test. Lisa does so well she's allowed to skip to the third grade, while Bart does so poorly that he must retake the third grade. Both are placed in the same classroom. On top of this, their teacher makes the two buddies when the class goes on a field trip.
