Six of the district's eight schools will have new principals this fall, and the top administrator also will be new.
Michael Escalante came from Palos Verdes Peninsula Unified to succeed J. Kenneth Jones, who recently retired from the Fullerton district after a decade as superintendent.
Escalante, 48, said his first task will be to build a team that can concentrate on bolstering student achievement.
"I see nothing but success with this strong administrative leadership and the outstanding teaching staff that each of our schools have," Escalante said. "We have the best and the brightest staff."
The new principals are Greg Franklin, Fullerton Union High; Jim Robinson, La Habra High; Karla Taylor, Sonora High; Chuck Maruca, Troy High; and Ron Gross, La Vista and La Sierra high schools.
