The show stars stand-up comedian and actor Gabriel 'Gabe' Kaplan as the title character, Gabe Kotter, a wisecracking teacher who returns to his alma mater, James Buchanan High School in Brooklyn, New York, to teach a remedial class of loafers, called "Sweathogs." Kotter's class is held in Room 11. The school's principal is referred to, but rarely seen on-screen. The rigid vice principal, Michael Woodman (John Sylvester White), dismisses the Sweathogs as witless hoodlums, and only expects Kotter to contain them until they drop out or are otherwise banished. As a former remedial student, and a founding member of the original class of Sweathogs, Kotter befriends the current Sweathogs and stimulates their potential. A pupil-teacher rapport is formed, and the students often visit Kotter's Bensonhurst apartment, sometimes via the fire-escape window, much to the chagrin of his wife, Julie (Marcia Strassman).
The fictional James Buchanan High is based on the Brooklyn high school that Kaplan attended in real life, New Utrecht High School, which is also shown in the opening credits. Many of the show's characters were also based on people Kaplan knew during his teen years as a remedial student, several of whom were described in one of Kaplan's stand-up comic routines entitled "Holes and Mellow Rolls." "Vinnie Barbarino" was inspired by Eddie Lecarri and Ray Barbarino; "Freddie 'Boom Boom' Washington" was inspired by Freddie "Furdy" Peyton; "Juan Epstein" was partially inspired by Epstein "The Animal"; however, "Arnold Horshack" was unchanged.
- Played by Gabe Kaplan
Gabe Kotter is a flippant, but well-meaning teacher who returns to his alma mater, Buchanan High, to teach a group of remedial students known as the Sweathogs. Being a founding member of the original Sweathogs, Kotter has a special understanding of the potential of these supposedly "unteachable" students. On his first day on the job, he launches into a Groucho Marx impersonation. Kotter is married to Julie, with whom he eventually has twin girls, Robin and Rachel. It was confirmed by Julie in the episode "Follow the Leader (part 1)" that Gabe is Jewish. During season four, Kaplan had contract issues with the executive producer, and only appeared in a handful of episodes. In season four, the invisible principal John Lazarus retires, and Kotter becomes the vice-principal. Though he is said to maintain some social studies teaching duties, most of that season's shows are filmed outside his classroom (#11), or if in room 11, Mr. Woodman is teaching. To minimize Kotter's absence, scenes were shot in either the school's hallway, the schoolyard, or the principal's waiting area. Season four ended the series.
- Played by Marcia Strassman
Julie Kotter is Gabe's wife and closest friend. Though she has a sense of humor, she often wishes Gabe would take matters more seriously. She is occasionally upset with the amount of time her husband spends with his students, and she is troubled that he allows them to visit their apartment regularly; in the two-part story arc "Follow the Leader", the Sweathogs' constant intrusions lead Julie to separate briefly from Gabe and even seriously consider divorce. Originally from Nebraska, with a college degree in anthropology, Julie eventually became a secretary, and later a substitute teacher at Buchanan after Gabe's promotion to vice-principal. She makes several references to her "world famous tuna casserole", a common meal at the Kotter dinner table, which Gabe and the Sweathogs dislike.
- Played by John Sylvester White
Michael Woodman is the curmudgeonly vice-principal (and later principal) of Buchanan High. He makes no secret of his dislike for the Sweathogs, whom he considers the bottom of the social register at his school. He refers to non-Sweathogs as "real" students. When Kotter was a student at Buchanan, Woodman taught social studies, the same class Kotter returns to Buchanan to teach. His old age, and sometimes his diminutive height, are common jokes with the Sweathogs. Woodman was totally against Kotter's unorthodox teaching methods (though as the series progresses, he begins to tolerate them marginally), and at one point even put Kotter in front of the school's review board in an unsuccessful attempt to have him fired. Nonetheless, in the season one episode "No More Mr. Nice Guy", Woodman is shown to be a gifted teacher, willing to wear historic costumes, and role-play in front of the class during his lessons.
Vincent "Vinnie" Barbarino
- Played by John Travolta
Vinnie Barbarino is a cocky Italian-American, and "unofficial official" leader and resident heartthrob of the Sweathogs. He has a need to be the center of attention, as seen when he admits to making it rain in the school gymnasium. In the two-episode "Follow the Leader," Barbarino quits the Sweathogs and drops out of school in anger when Freddy Washington is chosen as the "leader" of the group, though he returns as leader at the finish of the story. Barbarino's prowess with women is a source of envy (and more often amusement) among his classmates. On occasion, he breaks out in song about his last name sung to the tune of Jan and Deans' song, "Barbara Ann". He was the first of the Sweathogs to move out on his own when he got a job as a hospital orderly. In the first episode of the series and fourth season, he has a girlfriend, Sally. Vinnie is Catholic (often describing his mother as a saint), and, as shown in "I'm Having Their Baby", is a Star Trek fan. Little is known about Vinnie's home life other than that his parents argue a lot ("Follow the Leader (part 2)") and take turns beating him when in a mutual rage. His mother's name is Margie ("The Great Debate"), and he shares a bed with his brother. The episode "Don't Come Up And See Me Sometime" implies that Vinnie is the older of the two. Travolta himself was a high school drop-out. In Travolta's screen test for the series, Barbarino is Barbarini.
Arnold Dingfelder Horshack
- Played by Ron Palillo
The class clown of the Sweathogs, Arnold Horshack, is completely comfortable with his oddball, if naïve, personality. Horshack was known for his unique observations and his wheezing laugh, similar to that of a hyena. (Palillo revealed on a 1995 episode of The Jenny Jones Show that it originated from the way his father breathed during the last two weeks of his life as he lay dying from lung cancer.) It is possible that academically he is the smartest Sweathog. He is the only central Sweathog character to be promoted out of remedial academics class, but he soon returns after feeling out of place. He has an affection for acting and enjoys old movies, particularly 1930s musicals. He eventually marries Mary Johnson, a co-worker and fellow Sweathog. Although his surname sounds like a term for a bordello, he claimed it is a "very old and respected name" meaning "the cattle are dying." His middle name (and his mother's maiden name) is "Dingfelder."
Freddie Percy "Boom Boom" Washington
- Played by Lawrence Hilton-Jacobs
The hip, black student known as the athletic Sweathog for his skills on the basketball court, Washington claimed his nickname came from his habit of "pretending to play the bass" and singing "Boom-boom-boom-boom!". His trademark phrase is, "Hi, there" (spoken with a deep voice and a broad smile). Though often the voice of reason among his classmates, Washington nonetheless is a willing participant in the Sweathogs' various antics and pranks. Freddie also finds success as a radio disc jockey along with another former Sweathog, Wally "The Wow" (played by George Carlin). At one point, Washington challenges Barbarino for leadership of the Sweathogs, and even replaces him for a time until the group grows tired of his dictatorial style.
Washington has an older sister, who got divorced twice while living in Vermont ("The Longest Weekend"), and a brother, Leroy. In "The Great Debate" it is revealed that he has another brother, Douglas, and that his father's name is Lincoln. Kotter uses his own past to bond with Freddie, because in addition to being a former Sweathog he was also a former star of Buchanan's basketball team.
Juan Luis Pedro Felipo de Huevos Epstein
- Played by Robert Hegyes
A fiercely proud Puerto Rican Jew (when asked if his mother was Puerto Rican, Juan replies that his mother's maiden name was Bibbermann and that his grandfather saw Puerto Rico from the ship as he was making his way to America and decided to settle there instead of Miami, making him one of the earliest Puerto Rican Jews; Juan is thus Puerto Rican on his father's side and Jewish on both parents' sides), Epstein is one of the toughest students at Buchanan High, despite his short stature. He normally walks with a tough-man strut, wears a red handkerchief hanging out of his right back pocket, and was voted "Most Likely to Take a Life" by his peers. In the season one episode, "One of Our Sweathogs Is Missing", Epstein was said to be the sixth of ten children (When speaking on the phone to his mother (who had failed to notice that he had been missing for three days), she apparently failed to recognize his name and he had to further identify himself as "Number Six."), although he later mentions, in "I'm Having Their Baby," that his mother only gave birth eight times, implying two of them were twin births. Only four of his siblings are mentioned by name: his brothers Pedro, Irving, and Sanchez ("One of Our Sweathogs Is Missing"), establishing that some of his siblings had Jewish names and others Puerto Rican names, and a younger sister, Carmen ("A Love Story"). Epstein's toughness was downplayed later on, and he became more of a wiseguy. He was also known to have a "buddy" relationship with Principal Lazarus as he often refers to him by his first name, Jack. On a few occasions, when Kotter did his Groucho Marx impersonation, Epstein would jump in and impersonate Chico Marx or Harpo Marx. Epstein's diminutive height, large hair, and fake excuse notes (always signed, "Epstein's Mother"), are common jokes associated with him.
Rosalie "Hotsie" Totsie
- Played by Debralee Scott
Rosie Totsie is the femme fatale purported to have put the "sweat" in Sweathog, though her reputation is largely exaggerated by the Sweathogs' word of mouth. Her promiscuity is at least in part a reaction to the strict discipline enforced by her father, the Reverend Totsie. To restore her good name, and to prove a point, she fabricates a story about one of the Sweathogs getting her pregnant.
The character was a favorite among male viewers but was phased out of the series at the end of the first season when Scott was picked to co-star in the syndicated Norman Lear comedy, Mary Hartman, Mary Hartman. She reprised the role in a 1978 episode, "The Return of Hotsie Totsie", in which it was revealed that she dropped out of school because she became pregnant and had to become a stripper to support her infant child.
- Played by Helaine Lembeck
A recurring non-Sweathog character in the earlier seasons, Borden is a Straight A student and editor of the Buchanan Bugle, the school newspaper. She was Barbarino's tutor, and even dated him at one point. Despite her academic superiority, she can easily hold her own in a Dozens contest against any Sweathog.
Beauregarde "Beau" De LaBarre
- Played by Stephen Shortridge
Introduced as a regular character in the fourth and final season, Beau is a handsome, friendly, blond, silver-tongued southerner who transfers from New Orleans after being kicked out of several other schools. He ends up in Kotter's class. The producers sought a heart throb who was not a direct knock-off of the "Italian-Stallion" trend that was permeating Hollywood in the mid-1970s who would improve ratings in the South where the show's New York setting was seen as unrelatable. They wanted to retain female viewers, but avoid a Travolta clone. Beau's first reaction to the term "Sweathog" is, "That sounds gross." He seems to have a way with women, as shown in later episodes. One of his running jokes involves imparting whimsical sayings, such as one about how a real man never steps on a pregnant alligator.
Other recurring characters
- Vernee Watson as Verna Jean Williams, Freddie's girlfriend.
- Susan Lanier as Bambi, a female addition to the Sweathogs introduced mostly as eye candy.
- Charles Fleischer as Carvelli, introduced as a student foil to the Sweathogs in Season 2.
- Bob Harcum as Murray, Carvelli's loyal, and extremely dim, sidekick.
- Dennis Bowen as Todd Ludlow, a nerdy academic high achiever.
- Geoffrey Stump as Kyle "the Heartbreaker" Lucas
- Irene Arranga as Mary Johnson, later became Arnold Horshack's wife.
- Melonie Haller as Angie Grabowski, introduced in Season 3 as the only official female Sweathog but was gone by the end of the season.
Welcome Back, Kotter's first season was controversial. In Boston, the local ABC affiliate (WCVB-TV) initially refused to air the show. The city was going through a tumultuous school busing program that involved widespread protests and riots, and the local affiliate felt Kotter's fictional integrated classroom would only add fuel to the fire. However, the show became an early ratings success and the affiliate relented, picking it up from its fifth episode.
Teachers in other cities had concerns about how Kotter would be portrayed, so producers allowed a union representative on the set to ensure the show protected the image of those in the profession. Kaplan opposed the idea, at one point asking a reporter if there was a junkman on the set of Sanford and Son to protect the reputation of junkmen.
Notably, the show began 1975, the year Congress passed the Education for All Handicapped Children Act. The entire premise of this series deliberately centers around the mostly in-class activities of learning disabled...etc students. Audiences WERE supposed to fall in love with these particular characters. John Travolta especially became a teen heart throb. These students are required to be given a public education under law, but the principal is obviously not enthusiastic about their being on campus. Several episodes center around the tension between Mr. Kotter and the Principal. Mr. Kotter represents the early--and idealized special educators--who believed they would and could provide every student with an appropriate education if only the students had appropriate access to the correct services 
Censor sentiments of Juvenile delinquency faded after the Sweathogs' antics proved to be silly rather than criminal. Like Kaplan, Hegyes was a fan of the Marx Brothers. Hegyes claimed that he suggested that the Sweathogs be modeled after the Marx Brothers in order to reduce tension.
Ratings slipped greatly in the third season. Kaplan later attributed the decline to the age of the actors playing the Sweathogs, all then in their mid to late twenties, claiming that they were no longer believable as high school students. His idea was to have Kotter join the faculty of a community college attended by the Sweathogs; however, this storyline never materialized. In order to increase viewership, the Kotters had twin girls, but this did not prove to be enough to regain the show's earlier momentum. The show introduced a female Sweathog, Angie Grabowski, played by Melonie Haller.
Major changes took place in the fourth and final season.
Shortly before the season began, the series was moved from its successful Thursday 8:00 pm time slot to Monday 8:00 pm to make way for the impending hit series Mork & Mindy.
Virtually the entire writing staff was fired after season 3, and replaced with veteran writers from family-based series (such as Bob Claver from Leave It To Beaver and The Munsters).
Travolta, who had already starred in box office hits such as Grease, Saturday Night Fever, and Carrie, began to focus more time on his film career. He was featured in eight episodes, earning $2,000 for each one, and he was billed as a special guest star.
Mr. Woodman was promoted to Principal of the school (Principal Lazarus quit to take a "less stressful" job at a high-security prison), and Kotter was promoted to Vice-Principal, purposefully moving the show's focus away from Kotter's class.
Major off-screen disputes led Kaplan to break his contract and reduce his appearances. To help fill the voids, Stephen Shortridge joined the cast as smooth-talking Southerner Beau De LaBarre, and Kotter's wife, Julie, became a school secretary and occasional fill-in teacher, despite having one-year-old twin daughters.
Knowing the series was in a nosedive, producer James Komack attempted to spin-off a newly married Arnold Horshack into a new sitcom (see section below).
The show enjoyed ratings success during its first two seasons, spawning a host of merchandising tie-ins including: lunch boxes, dolls, comic books, novels, and even a board game, advertised as "The 'Up Your Nose With A Rubber Hose' Game" in a commercial with a class full of Sweathog look-alikes featuring Steve Guttenberg as Barbarino. The Sweathogs (or at least an impressionist's version of them) even made a crossover appearance with characters from the Happy Days universe on one track (the disco-themed "Fonzarelli Slide") of a 1976 TV-promoted oldies compilation album.
In 2010, the cast, including: Gabe Kaplan, Marcia Strassman, John Travolta, Robert Hegyes, Lawrence Hilton-Jacobs, and Ellen Travolta were honored at the TV Land Award ceremonies that year. Co-star Ron Palillo was not in attendance.

The popular theme song, "Welcome Back", written and recorded by former Lovin' Spoonful frontman John Sebastian, became a No. 1 hit in the spring of 1976. The show was originally going to be called Kotter, but that was changed because of the theme song lyrics. Sebastian has said he tried to find a more general theme for the song after being unable to find any reasonable rhymes for Kotter.
Sebastian performed the song on Saturday Night Live (April 24, 1976 – Season 1, Episode 18), and memorably flubbed the opening lyrics.
DC Comics published ten issues of a Welcome Back, Kotter comic book starting in 1976. Following its cancellation in 1978, a Limited Collectors' Edition was issued, incorporating a 4-page "On the Set" section and photographs from the show.
A series of novels based on characters and dialog of the series was written by William Johnston and published by Tempo Books in the 1970s.

Kotter failed to receive any major awards, though it was nominated for an Emmy Award for Outstanding Comedy Series in 1976  after its first season; it lost to The Mary Tyler Moore Show. The series was also nominated for three technical Emmy Awards: Outstanding Achievement in Videotape Editing for a Series (to Editors Susan Jenkins and Manuel Martinez) in 1976, Outstanding Art Direction for a Comedy Series (to Art Directors Roy Christopher and James Shanahan) in 1978, and Outstanding Individual Achievement – Creative Technical Crafts (to Dick Wilson for sound effects) in 1979.
Several noteworthy performers enjoyed guest stints on Kotter either during or prior to their widespread fame. James Woods guest starred in the first season ("The Great Debate") as Alex Welles, a drama teacher who leads the school debate team ("the Turkeys") in a competition against the Sweathogs. Pat Morita appears in the 1976 episode "Career Day" as Mr. Takahashi. Comedian George Carlin was featured, as was John Astin. Other guest stars included Scott Brady, Ellen Travolta, Richard Moll, Della Reese, and Dinah Manoff who would work with John Travolta again in Grease.
Groucho Marx was set to have a brief walk-on role in one episode. He arrived on-set, but was deemed to be too sick to appear. Pictures of Marx with the cast were taken, but were never released because of his sickly appearance.
At least three spin-offs of Kotter were seriously considered, but only one ever became a series. The short-lived Mr. T and Tina starred Pat Morita as Taro Takahashi (Mr. T for short), a brilliant Japanese inventor whom he portrayed in one episode of Kotter. The show was not received well by critics and lasted for five episodes on ABC. There was also talk of developing a spin-off built around the Horshack character and his family, Rich Man, Poor Man; Horshack!, but it never went beyond the backdoor pilot stage, shown as an episode of Kotter. In the mid-1990s, Hegyes announced on The Jenny Jones Show that plans were in the works to create a spin-off featuring the Sweathogs (minus Travolta's Barbarino) all grown up. The project, however, never got off the ground, and little information about it was ever made public.

After the show
Kaplan welcomed back Hegyes and Jacobs on his short-lived 1981 sitcom Lewis & Clark. Their characters joked that Kaplan seemed familiar and being a smart guy, "should become a teacher."
The Simpsons referenced the sitcom in the fourth-season episode "Selma's Choice" (episode 9F11), first aired on January 21, 1993. Marge is impressed to find one of the Sweathogs listed as a donor in the Springfield Sperm Bank’s “101 Frozen Pops” catalog. She is disappointed, however, to learn from Selma that it’s not Horshack.
In 1997, Ron Palillo, Robert Hegyes, and Lawrence Hilton-Jacobs reprised their respective roles in a dream sequence in the Mr. Rhodes episode "The Welcome Back Show".
In 2012, both Ron Palillo and Robert Hegyes died. Other members of the cast who have died include Marcia Strassman in 2014, John Sylvester White in 1988, and Debralee Scott in 2005.
As of March 2016, the show airs on Me-TV Sunday mornings at 8:00 am and 8:30 am ET.
The show's lunchbox was the subject of the season one finale of the podcast Mystery Show.
