The biggest adjustment will come at the headmaster position, where Dave Granville is set to take over the leading role.
Headmaster Robert Foust, who has been in charge for 11 years, will act as headmaster emeritus and remain at the school to help Granville during the transition period.
"This is not a retirement — I will still work in an advisory position and be there for him during the transition," said Foust. "The board and I have been talking about this for a couple years."
Granville has been the headmaster at Simpson Academy in Mendenhall for the past four years and is completing his 10th year in the Mississippi Association of Independent Schools.
He will continue his duty at Simpson for the remainder of the school year.
He previously spent six years at Chamberlain-Hunt as a teacher, athletic director, coach, commandant and chief of staff.
"I'm very excited about forming the partnerships between myself and the students, staff and the community," said Granville. "Like any good leader, my goal is to form positive relationships with everybody.
"We will continue to improve academics and the life goals of Bayou's students."
Granville said he has been impressed by Bayou Academy's growth under the direction of Foust.
"Bayou Academy has taken great strides under the leadership of Mr. Foust and we will work together to set the bar even higher — academically and athletically," said Granville.
Foust said he's honored to remain part of the school and continue the success.
"My main functions will be there to help with finances, scheduling, public relations and providing institutional history," said Foust. "I'm glad to do whatever he needs me to do and answer whatever questions he has.
Some of the accomplishments Granville was able to implement at Simpson included: ACT average score improvement from 19.1 to 23.2; MS Scholars improvement from 33 percent to 76 percent this year, and a substantial increase in scholarships.
He has coached many sports and enjoyed success in basketball, leading the boys at Chamberlain-Hunt to a state runner up in 2009.
Granville led the Simpson girls basketball program to a 56-23 record in the past two seasons, with two south state runner-ups and a fourth and fifth place state finish.
He has also served as a karate instructor, college basketball assistant and worked at the Ford Family Service Center.
He has a physical education degree from the University of Delaware and a Masters of Education from the University of Cincinnati.
"My wife and I are very excited about moving to the area because it looks like a great place to live," said Granville.
Rodney Flowers, the current assistant headmaster who began at the start of this academic year, will return to the Oxford area to spend more time with family.
The school has also announced Jimmy Hicks as the new athletic director, head of football operations and high school head football coach.
Foust said there would be some new faces at the top but Bayou has exciting times ahead.
"I've been the headmaster for 11 years and it's been great," said Foust. "My heart is still with the school. It's never been a job — it's a passion.
"The timing is right for someone else to take over the daily tasks of running the school."
