JACKSONVILLE, Fla. -- Part of Martin Luther King's legacy included the importance of education for young students.

Saturday, 400 students, teachers and parents honored King's legacy at the Second annual One by One Convention at the Prime Osborn Convention Center.

The convention was twice as large as last year, according to organizers.

Duval County Superintendent, Doctor Nikolai Vitti was at the event.

"Our teachers and administrators need to realize that our clients are our students," said Vitti. "And, if they aren't served at the highest of levels, then something needs to be done differently."

So what is the superintendent doing?

He has reassigned 11 principals in the district to improve schools academically.

Duval high schools made a 70 percent performance scoring either an "A" or "B" grade.

Nine local high schools scored the top grade--

and five received a "B".

Only one high school, Raines, scored a "D" and no school got a failing grade.

Vitti says events like this continue to move the district towards a better report card.
