After a long year of bonding experiences, the Wacky Homeroom finishes up its school year, and will soon begin its next one. But if there are multiple homerooms in the school, there's a chance that the students from last year's homeroom could get split up. The students will have to make new friends and adjust to a new classroom environment.
But wait! When the student rosters are posted, it turns out the True Companions get to spend another year together. They've even got the same teacher as last year. What a wonderful turn of events.
Of course, the writers don't want to waste all of the character development that occurred over the previous year. Splitting apart the group of friends that form the central cast of the story is suicide, and it's a waste of a character to put Sensei-chan on a bus every year when the class is assigned a new homeroom teacher. So the classroom doesn't change.
Very commonly seen in school dramas or comedies in Japan. Typically does not apply to high schools in Western settings, due to the fact that homerooms either do not exist or are rarely used.
This trope applies only when the possibility exists that the characters could change class. This trope does not describe one-room schoolhouses or schools that keep all the students in the same class for their entire school careers.
Compare California University.
- Azumanga Daioh has this, although minor character Kaori does get moved to a different homeroom for senior year. Kagura also gets moved into Yukari's class in the second year. Yukari arranged for this purely so that she wouldn't be inconvenienced by having to learn the names of a new batch of students.
- Averted and discussed in Girl Friends, when the characters move from second to third year. The main couple stay in the same class, but they gain a new social circle and slowly lose contact with their old friends.
- While art students in Hidamari Sketch don't have to concern themselves with the shuffle (by contrast, general studies students do):
Miyako: Yunocchi! Look! We're in the same class again this year!!Yuno: That makes three years in a row!Miyako: Yay!Nakayama: ...Mami: Yuno-san. Miyako-san. What are you doing...?Miyako: Pretending class changes are possible!Yuno: I've always wanted to try it...
- Kaguya-sama: Love is War:
- Averted in the backstory, where it's mentioned in We Want to Talk About Kaguya that the resident Four-Girl Ensemble were all classmates in their first year before being split up in their second.
- Inverted on a wider scale. At the start of the series, all the named second year characters are scattered between three different classes (something which is a plot point on several occasions), but they're all grouped together when they enter their third year. This is justified by the fact that the principal knew Kaguya would probably be facing hardships in the near future and made sure to fill the class with all her friends to support her.
- Averted in Kaiju Girl Caramelise. Arata and Kuroe end up in different classes when the new school term starts in volume 3. Kuroe ends up in the same class as Manatsu, who was in a different class the previous year.
- Invoked in Kodomo no Jikan. Aoki wants to keep an eye on Rin and knows better than to separate her from her friends.
- Inverted in K-On!: Mio is in a different class first year and stays that way second year... but then is grouped with everyone else on the third.
- Negima! Magister Negi Magi - All 31 girls get put in Negi's homeroom for their third year. Handwaved in that Mahora doesn't split up its classes.
- Slightly justified in Rosario + Vampire. Tsukune happens to be in the same class as his Unwanted Harem because the headmaster placed everyone who knew his secret into the same class.
- Parodied in Sayonara, Zetsubou-Sensei: The entire class stays together, with the same homeroom teacher...because they've all been held back a year. (This happens the first time they would normally have gone on to the next grade level; ever since then the manga has run on Comic-Book Time with the seasons changing but no one aging.)
- In the Urayasu Tekkin Kazoku sequel manga, all of the main characters are in the same class together when they enter the third grade including Jin who was from a different class always visiting in the predecessor. Hanako on the other hand, was in a different class until becoming their classmate a few chapters later the same time they got their old teacher from the second grade back.
- On Boy Meets World, this is done with Cory, Shawn and Topanga at the start of season two and briefly mentioned at the start of season three. Every year after that they continued to be in the same class together (and have the same teacher), but this is never addressed again in-show.
- Spin-Offspring Girl Meets World highlights this in the Season 2 premier, Girl Meets Gravity. They start off in the same classroom, with the same classmates, but a different teacher. They quickly drive the teacher to quit and Cory is once again their teacher. Riley and Maya attempt to transfer, but wind up in a class full of Suspiciously Similar Substitutes where they are no longer in focus. They transfer back.
- Annie on Community actively works to invoke this trope at the end of season one, going so far as to risk all of her students failing class so they can stay together. Ultimately, the study group consciously picks a class to take together
- Head of the Class justifies the trope by having the class in question be the school's gifted program. The kids are so smart that regular classes are too easy for them, and most teachers are unable to sufficiently challenge them, so they're all gathered together and put into one class with a teacher who is able to handle their skill level (and assorted eccentricities). Other teachers and students are occasionally shown, but rarely on a regular basis.
- Welcome Back, Kotter keeps the Sweathogs in Kotter's class every year, arguably on the basis that he's the only teacher willing to put up with them (being a former Sweathog himself).
- Mostly averted on Ned's Declassified School Survival Guide, where the kids are shown to be in different level classes based on skill, get new teachers when they move from 7th to 8th grade, etc. (the fact they don't have the same classes together as the year before is even a plot point in the pilot). However "evil" science teacher Mr. Sweeny does follow them up from 7th to 8th (to their collective horror) and the class is populated with the same few recurring characters as before.
- Not having the same teachers in 7th grade as 6th but having the 7th teachers again in 8th can be Truth in Television, as many states divide teacher certification into K-6 elementary and 7-12 secondary levels. This often leads to two full sets of core-subject teachers in 6-8th grade middle schools.
- Downplayed in Ensemble Stars! - when the second-years move up a year, the classes stay mostly the same, but Souma and Adonis switch from class A to B while Mao switches to A. This allows Souma and Adonis to retain their Those Two Guys relationship (especially since almost all of Souma's other friends have now graduated), and since Mao has good friends in both classes he could go anywhere.
- Averted in Educomix. After the nursery kids leave nursery, Eyeclops and Drug Abuse go to a different school from Happy, Zkt, and Qstickman.
- Averted in El Goonish Shive. During first semester of their senior year of high school, Sarah, Susan, Elliot, and Tedd shared the same lunch period. During the second semester, the girls have a different lunch period from the boys and instead share it with Catalina.
- Played with in Arthur. Bear in mind that the characters are permanently in third grade. In a Flash Back to when they were all in the second grade, they were watching the postings to see who got into which third-grade class. Several characters there were implied to be Arthur's True Companions who aren't series regulars, because they got put in the other third-grade class.
- Truth in Television for many British schools, where form groups, as well as lots of other classes in lower school, aren't mixed up without any particular reason to do so.
- Some schools assign homerooms alphabetically, so the same people are in the same homeroom every year. This makes sense, since homeroom is usually just a few minutes at the beginning of the day where attendance is taken and announcements are made. Other classes will usually be mixed.
- In some special education settings, students in multiple grades are grouped according to their skills and needs and taught together in specially-designated resource rooms or classrooms.
