The immediate sequel to ''Series/DegrassiJuniorHigh'', and the show that solidly transformed the ''Degrassi'' series into a full SoapOpera. This series lasted from November, 1989 to January, 1991. A total of 28 episodes in two seasons.

Most of the episodes focused on the day-to-day problems of being a teen, such as bargaining for more freedom from your parents, preparing for life after graduation, and (especially) the perils and pitfalls of NoGoingSteady. Every few episodes, a monster problem would hit, like AIDS, a kid running away from home, and so on. However, the cast were such a DysfunctionJunction that the day-to-day episodes could feel almost as soap-opera and dramatic as the heavy-hitter ones. Without exception, every single storyline had a follow-up later.

Like the rest of the ''Degrassi'' franchise, the series was intended as a tool for teaching teens about "hot-button" issues like abortion and AIDS. In many ways, it serves as a bridge between the individual episode focus of ''Series/DegrassiJuniorHigh'' and the sprawling SoapOpera of ''Series/DegrassiTheNextGeneration.'' But in spite of that, it was far more continuity-heavy than ''Series/DegrassiTheNextGeneration,'' with its ThreeMonthRule and HeelFaceRevolvingDoor.

At its best, ''Series/DegrassiHigh'' turned LoadsAndLoadsOfCharacters into TrueCompanions with a bond so real you could taste it, and a school that felt more real than almost any other on TV. It still has a ton of die-hard fans who love it like ''Franchise/StarTrek'' fans love their continuity. At its worst, it could be frustrating stew of too many SpearCarrier characters and repetitive romantic subplots, made worse by regular RetCon. The most striking innovation of the show was that all characters had SoapOpera adventures even when the camera wasn't on them, and time visibly passed each episode -- which made everything fit together, but also meant a ton of SecondHandStorytelling.

The series ended with a GrandFinale movie, ''School's Out,'' which caused an outcry by going DarkerAndEdgier than anything ''Degrassi'' (or almost any other teen show) had done at the time, with tons of FanService (from actors who were real teenagers), drugs and alchohol, sex scenes, and characters turning very unpleasant. Most notable was using real cursing in a show that had never had it before -- one foul-mouthed line became an instant MemeticMutation. Like many DarkerAndEdgier shows, fans tend to either love it or hate it. (Of course, compared to ''Series/DegrassiTheNextGeneration'' it feels almost quaint in a lot of ways -- and yet, still DarkerAndEdgier in others.)

The series was followed up with ''Degrassi Talks,'' a documentary special where ''Degrassi'' actors interviewed people for real stories of drug addiction, domestic abuse, etc. interspersed with relevant clips from ''Series/DegrassiHigh.''

!!This show provides examples of:

* ADayInTheLimeLight
* TheAllegedCar: Clutch's Mustang II, Joey's older (but cooler if no less junky) Mustang Sportsroof, Snake's parents' huge, rusty '76 Oldsmobile, Spike's mom's Lada, Wheels' heavily beat-up Chevy Malibu wagon. It gives the impression that the production could only afford Alleged Cars for the characters to drive.
* AnAesop
* AllForNothing: Constantly.
* AllLoveIsUnrequited: Just like in ''Series/DegrassiJuniorHigh'', it's very frequent.
** Heather's crush for Wheels.
** Alex likes Tessa, who has a crush on Joey (who doesn't seem to notice her until TheMovie).
** Arthur loves Caitlin who is interested in Claude.
** Spike likes Snake, but he has still a crush on Michelle (ironically since in ''The Next Generation'', Snake and Spike are a married couple).
* AlphaBitch: Averted when Stephanie Kaye left ''Series/DegrassiJuniorHigh'' -- this may be the only teen SoapOpera without one.
** Amy and especially Allison though they are only minor characters.
* AntiHero: Wheels.
* AscendedExtra: Maya, Michelle, Diana, Alex, Dwayne and Tessa. All of them were minor or background characters in ''Series/DegrassiJuniorHigh''.
* BadassBeard: Scott the abusive boyfriend

* DarkFic: ''School's Out'' according to those who find it overdone.
* {{Deconstruction}}: ''School's Out'' according to those who think it's an appropriate BittersweetEnding.
* DemotedToExtra: Arthur and Yick. Along with Stephanie Kaye and Joey, they were the main stars of ''Series/DegrassiJuniorHigh'' (especially in season 1), and were often involved in a subplot in every episode. But no longer cute little kids, they were relegated to minor background players in ''Series/DegrassiHigh''.
** Melanie. She has even less screen time than Yick and Arthur in ''Series/DegrassiHigh''.

** Tessa and Alexa seem to enjoy it.
* FanService: In ''School's Out''.
* FawltyTowersPlot
* FormerChildStar: RealLife example: of the show's actors who stayed in acting, most were hopelessly type-cast. A few of them even ended up playing the same characters on ''Series/DegrassiTheNextGeneration''; although this would likely fall under CastingGag.
* FreudianExcuse
* FunnyBackgroundEvent: While Joey and Caitlin are sharing an emotional moment at the talented show, Wheels is dancing in the background in his Mexican outfit (complete with a huge sombrero covering his head).
* GentleGiant: Snake.
* {{Gonk}}: Nick.
* HeelFaceRevolvingDoor: Dwayne.
* HopeSpot: In the first episode.
* HustlingTheMark: In one episode, the cool kids invite nerdy, insecure Arthur to their poker party so they can take him for all he's worth. He's totally out of his depth -- at one point, he asks, "does three of a kind beat a full house?" But he suddenly starts winning, and by the last hand, it's down to Arthur and the host ...and Arthur wins almost all the money by bluffing when his hand is complete junk. The cool kids are amazed, then Arthur grins and says, "'Does three of a kind beat a full house?' You guys are so gullible.".
* {{Irony}}: Wheels lost his parents to a drunk driver, [[spoiler: he ends up taking a life while driving intoxicated.]]
* ItIsPronouncedTroPay: Pretentious Claude insists on having his name pronounced in the same manner as "clone".
* IWantMyBelovedToBeHappy
* {{Jerkass}}: Dwayne's minions and later Wheels after his FaceHeelTurn.
* JerkJock: Dale.
* JerkWithAHeartOfGold: Joey. In ''School's Out'' he's more of a JerkWithAHeartOfJerk.
* KarmaHoudini: The only penalty Luke ever faces is losing some money.
* KilledOffForReal: [[spoiler:Claude]].
* KudzuPlot: The use of SecondHandStorytelling means we simply never find out how some things happened.
* LiteralGenie: A complicated one in ''School's Out''.
** Joey wanted to get laid. He got Tessa and Caitlin.
** Wheels didn't want to live with his grandparents. He isn't living with them at the end.
** Caitlin wanted to choose between university and love. Joey made the choice very easy for her.
** Snake wanted a lifesaving fantasy, but he still didn't lose his virginity.
* LivingInAFurnitureStore
* LoonyFan: RealLife example: Sara Ballingall, who played Melanie, was stalked for ''six years'' by a crazed Australian fan who kept an armory in his house.
* LoveTriangle: Joey, Caitlin, and Claude were the main one.
* MagicalNegro: BLT, Maya, and Patrick, a rare Magical Irishman.
* TheMagicPokerEquation: Subverted in "The All-Nighter".
* TheMasochismTango: Joey and Caitlin, despite being deeply in love, would clearly make a horrible couple in the end, and some characters point this out in the show.
* NaiveEverygirl: Melanie, although she's a bit toned-down since ''Series/DegrassiJuniorHigh''. Michelle also.
* {{Narm}}: Dwayne's kicking rampages are hilarious since he can barely lift his legs, and the ''Degrassi Talks'' theme song has a very 1980s sort of cheesiness to it; also done in-universe with one of Lucy's videos.
* NoGoingSteady
* NoRespectGuy: Snake in ''School's Out''. It made no sense when you consider he had multiple girls interested in him all through junior high and high school, and was respected by everyone.
* TheOjou: Lucy.
* OneOfUs: Tomboyish L.D. is clearly shown reading, of all things, a David Eddings book.
* PluckyGirl: Spike and Michelle.
* PositiveDiscrimination: Averted -- even with three MagicalNegro characters, some of the most unpleasant characters on the show are minorities.
* PrecisionFStrike: The F-word is used ''twice'' in near-succession during the climax of "[[TheMovie School's Out]]". Extremely jarring in that the show hardly ever used even ''mild'' swearing. Notable in that it's the first use of the f-word on Canadian television.
* ProductPlacement: Lots of appearances by Pepsi and Quaker Oats: including a character who almost always seemed to have a box of Dipps granola bars..
* PutOnABus: Many. However L.D. is still mentioned by Lucy even in the last season.
* RealLifeWritesThePlot: the opening sequence has a scene of Arthur's bike getting smeared with peanut butter -- part of a bullying plot that was canceled when Arthur's actor suddenly hit his growth spurt.
* RetCon
* RomanticFalseLead: Claude.
* SchoolNewspaperNewshound: Lucy is a school ''film'' newshound.
* SecondHandStorytelling
* ASimplePlan
* SlumberParty
* SmugSnake: Luke.
* SoapBoxSadie: A whopping four of them -- Caitlin, Claude, Liz, and Lucy, and each one with a distinct style.
* SpearCarrier
* SpoilerOpening: The credits spoil a few things; far worse is the decision to put the ''Degrassi Talks'' episodes on the ''Series/DegrassiJuniorHigh'' [=DVDs=], making it impossible to watch them in the order you see the discs without spoiling the biggest surprises.
* StarCrossedLovers: Joey and Caitlin -- arguably one of the best examples to ever come out of a TeenDrama series.
* StylisticSuck - showcased spectacularly in the Talent Show auditions, here: http://www.youtube.com/watch?v=HdC5lOHkEZ8&feature=relmfu
* SmallNameBigEgo: Joey.
* TeenDrama
* TerribleTrio: Dwayne, Tabi, and Nick. A huge dose of suspension of disbelief was needed to believe this very non-threatening looking trio could be Degrassi's top bullies.
* TookALevelInJerkass: Wheels and, to a lesser extent, Yick.
** Joey in TheMovie.
* TookALevelInKindness: Kathleen.
* ThoseTwoGuys: Amy and Allison.
* ValleyGirl: Amy and Allison.
* WhereDaWhiteWomenAt: BLT and Michelle
* WildTeenParty
* ZanyScheme
