He replaces Jim Carpenter, who left Jefferson High School to become an assistant principal and athletic director at Martinsburg High School.
Arvon graduated from Shepherd College in 1977 with a bachelor of science degree in education and a received a master's degree in 1983 from Marshall University. He received his professional principal's certification in 1988.
Arvon and his wife, Debra, have two children, Marc Victor II, 9, and Addison Chase, 6. They live in Hedgesville, W.Va.
Jefferson County school Superintendent David W. Markoe said that Arvon had good experience with a schools-to-work program at Sherman High School and set up a block schedule system.
Jefferson High School has no plans to go with a block schedule system, but his experience would help if the school system decides to do so in the future, Markoe said.
"We feel very confident he'll go to Jefferson High School and do a good job for us there," Markoe said.
Arvon was not at the meeting Wednesday and could not be reached for comment.
The school board also appointed Lynn D. Holcomb-Kornegay as assistant principal.
She is currently an assistant principal at Paul Laurence Dunbar High School in Washington, D.C., and is an adjunct professor at Shepherd College. She is also a captain with the 167th Air Lift Wing with the West Virginia Air National Guard in Martinsburg, W.Va.
Holcomb-Kornegay is the mother of two children, Kristopher, 5, and Kaitlynn, 3.
School officials said a third assistant principal was needed because of the school's growth.
The school is expected to have 1,475 students at the start of the 1997-1998 school year.
The school is currently undergoing extensive renovation and addition work to add ninth graders to the high school and also to prepare for an increase of students as the county grows.
