From Dragon Ball Wiki, the ''Dragon Ball'' encyclopedia
Turtle School is one of the martial arts schools founded by Master Roshi which presumably continues the teachings of Roshi's former sensei, Master Mutaito. The first two known members of the school are Grandpa Gohan and Ox King. Other known students of the Turtle School include Goku, Krillin and Yamcha. The special moves which are taught to the students there are the Kamehameha and Jan Ken.
In Dragon Ball Online, Master Roshi has officially retired, though (the now presumably deceased) Krillin founded the New Turtle School after reading Gohan's book "Groundbreaking Science". In-game, Spiritualist class belongs the human species and excel in use of spiritual energy rather than physical fighting. Spiritualists may obtain the status of a Turtle Hermit through the New Turtle School or a Crane Hermit through Tien's New Crane School. Krillin decided that the New Turtle School should put emphasis on teamwork - whereas in the anime, Master Roshi had Goku and Krillin work against one another.
Canon techniques of the Turtle Hermit master class are Krillin's Scattering Bullet and Goku's Super Kamehameha, while all Spiritualists learn the Destructo Disk, Kamehameha, and even Yamcha's Spirit Ball. Dragon Ball Online's Martial Artist class builds warriors similar to both Goku and Yamcha from the early arcs of Dragon Ball, who were at the time students of Master Roshi. Martial Artist techniques are Jan Ken and Wolf Fang Fist (though this isn't a technique of the Turtle School, only being used by the practioner Yamcha), and also obtain a Concentrated Kamehameha technique.
Both Turtle Hermits and Fighters (an optional master class for Martial Artists, the other being Sword Master) use rods as their sub-weapons to perform certain class-excluse techniques.
The graduates of Master Roshi's training often include the kanji for "Turtle" ("Kame") 亀 on their dogi. Characters related to Goku always seem to wear the Turtle School colors of orange and blue in homage to Goku yet do not wear the insignia. This is possibly a sign of respect for him or that the creator Akira Toriyama wished for the viewers to the visual likeness between him and his sons. First, his son Gohan is given a replica of Goku's gi in the early and later arcs of Dragonball Z, except that Gohan wears Piccolo's "demon" kanji rather than the Turtle School insignia during the Saiyan Saga. Had his father not abandoned the Turtle School's insignia, Gohan too would have worn it in his battle against Buu. Future Gohan also wears his father's colors (but with a replaced kanji) after his death, though it is worth noting that Future Gohan did not attend nor graduate from the Turtle School.
Goku's second son Goten also doesn't sport the Turtle School insignia despite wearing the Turtle School colors, and in adulthood (the last episodes of Z), abandons the blue undershirt and keeps a similar kanji-less gi (in a similar fashion worn by Goku during his battle with Raditz). Neither of his sons have been students of Master Roshi, despite knowing the Kamehameha. This could be due to Goku and the other Z Fighters surpassing Master Roshi and taking it upon themselves to train the younger generation of warriors.
By the end of Dragon Ball Z, Goku has abandoned the orange and blue colors completely, however, Goku's granddaughter Pan wears an orange gi during the same period. In Neko Majin Z, Goku's disciple always wears his colors in the same fashion, yet wears a different symbol, "ne".
In Dragon Ball Online, the central cast of Dragon Ball Z had become famous through Gohan's book Groundbreaking Science. In Age 1000, humans still wear the Turtle School gi/colors (though it sometimes personalized with black and orange, rather than blue and orange), but it is generally associated with the offensive melee class (Martial Artist) rather than Spiritualists, which become Turtle Hermits.
