The 2016-17 school accountability grades are out for Okaloosa, Santa Rosa and Walton counties.

The Florida Department of Education tallied the school grades and released them Wednesday, based on student assessment and end-of-course exam scores.

Stacked against other schools in the state, Okaloosa and Santa Rosa schools came out on top, with every school in the two districts earning a passing grade. 

Okaloosa kept its overall A grade and Santa Rosa County advanced from a B to an A district.

In Okaloosa County, Riverside Elementary School in Crestview went from a C to an A-rated school this year. Choctawhatchee and Crestview high schools advanced from a B to A rating.

Laurel Hill School and Longwood Elementary School were the only two schools in the district to receive a C.

Marcus Chambers, assistant superintendent of curriculum and instruction, said Okaloosa County received the highest percentage of A's, 71 percent, in the state.  

"The release of the school grades from the state of Florida highlights the fact that our school district as a whole is healthy," Chambers said. "We couldn't be prouder of our students and the hard work of our teachers, staff and administration. 

In Santa Rosa County, six of its schools advanced a letter grade this year. 

Central School, Bagdad Elementary School and East Milton Elementary School were the only three in the district to receive a C.

Bill Emerson, assistant superintendent for curriculum and instruction, said Santa Rosa is very excited to move back up to an A district. 

"It's a culmination of a lot of hard work from our teachers, staff and students," Emerson said. "We will be happy but continue to move forward."

The Walton County School District also fared well, finishing the year as a grade B district.

"I think we are very pleased with our grades," said Kay Daily, the superintendent of curriculum and instruction. "B is a good grade, but we were one point away from an A. It's a little bittersweet, but we know where we need to improve."

Maude Saunders Elementary received Walton district's lowest grade, a D. The school was among the state's 300 lowest-performing elementary schools in 2016-17. 

Daily said the district plans to provide more human resources, classroom support and instructional staff to Maude Sanders.

"They are a high poverty school," she said. "We know that's not a direct correlation, but it is a direct impact."

Paxton School increased from a B to an A, Mossy Head Elementary School moved up from a C to a B, Freeport Middle School went up from a C to a B and Bay Elementary School improved from a B to an A.

Overall, Okaloosa County ranked second in the state with a 66 percent of total possible points. Santa Rosa County ranked eighth with a 63 percent, and Walton County ranked 12th with 61 percent.
