Springfield Elementary students
Milhouse Van Houten
Milhouse Van Houten is Bart's best friend and has been since kindergarten. While Bart often sees him as uncool, he always hangs around with him, pulling Milhouse into his schemes. They have occasionally argued and broken their friendship, mainly over girls, but they are still often good friends.
Nelson Muntz has a mixed relationship with Bart. He often bullies him, and Bart even made an army to defeat him. Then again, they are also often seen as friends, and Bart even decided that he was more trustworthy than Milhouse, his long time best friend. Their relationship often swings from being friends to being enemies.
While Bart generally dislikes Martin Prince, Jr. as he is smarter than him and a nerd, Bart has had to ask him for help occasionally. When Bart was failing and had the threat of retaking fourth grade again, he asked Martin to help him. In return, Bart helped Martin have fun. Bart again had to ask Martin for help when he wanted a good science fair project and together they made the Robopet.
Springfield Elementary staff
Principal Seymour Skinner can be seen as Bart's enemy, foiling him in his plans. Bart has been punished by Seymour often. Despite this though, Bart often helps out Seymour with his problems, helping to reunite him and Edna Krabappel. After Skinner got fired as principal, he and Bart became friends, with Bart often checking in on him and they started to enjoy each other's company. After Skinner becomes principal again, they both decide that they can no longer be friends.
Edna Krabappel is Bart's homeroom teacher who constantly has to put up with Bart's endless misbehaving in class. Nevertheless, Edna does all she can to help Bart succeed in school. Often, Bart has tried to save Edna and Seymour's relationship showing that he cares about her. When he accidentally got her fired, he went to see her often.
Superintendent Chalmers is generally Bart's enemy by association, due to his position as Principal Skinner's boss. However, they became friends and developed a mutual respect when Skinner put Chalmers in charge of Bart's education. Chalmers taught Bart about Theodore Roosevelt (in the process succeeding in getting Bart interested in learning), and when Chalmers was fired, Bart staged a takeover of the school and succeeded in winning Chalmers his job back.
Otto Mann is Bart's bus driver. Bart looks up to Otto like a big brother, and he even asks Otto for some helpful advices when it comes to being cool, manly, or dealing with the bullies.
Willie MacDougal is the school's groundskeeper who shows great hatred for Bart for being the butt of Bart's jokes. However, even though Bart annoys him greatly, he once saved Bart by defeating a pack of wolves by wrestling them to submission.
Bart seems to be in good terms with Ned. This was shown when Homer first brought home a pet pig and paid more attention to it than Bart, which made Bart feel left out and this caused him and Ned to spend more time together and they became good friends.
Krusty the Clown
Krusty the Clown is Bart's idol. Bart has helped him out several times, firstly saving him from prison, saving his career and reuniting him with his daughter. However, Krusty can never remember Bart and also can never remember all the things he's done for him.
Sideshow Bob became Bart's major archnemesis after Bart and his sister Lisa investigated a robbery for which Krusty had been jailed. They discovered that Krusty was innocent and that Bob had framed him for the crime, which resulted in Krusty's being freed and Bob's being thrown him in jail. After that, Sideshow Bob got out of prison and tried to kill Bart for revenge but failed due to Bart's outwitting him. Bob has since attempted several other criminal capers (including further attempts to kill Bart), but has so far been foiled every time by the Simpson siblings.
