Monroe County students are the best at geometry in the state according to end-of-course exam results reported by the Florida Department of Education.
Of the 599 Keys students who took the computer-based test, 84 percent earned a score of three out of five or higher; a three is needed to pass.
An average of students taking the test in all 67 school districts yields just 63 percent earning a score of three or higher.
Monroe students achieved a raw score of 418 (out of a possible 475) compared to a statewide average raw score of 403.
Superintendent Mark Porter said the impressive scores are "representative of the outstanding commitment to excellence in Monroe County schools."
He attributed the success to intensive geometry boot camps, real life problem-solving, project based learning, collaborative group work and promoting student access to digital content, among other classroom efforts.
"We continue to celebrate the students and teachers who have worked diligently throughout this year to increase achievement in geometry across all grade levels in the district," Porter said.
"This is an area of deliberate practice that we have identified to assess the changes in instruction that led to the significant improvement district wide."
Since 2011, Florida has been replacing the Florida Comprehensive Assessment Test (FCAT) with subject-area specific, end-of-course examinations.
The new testing standard goes hand-in-hand with a transition from Sunshine State grading standards to Common Core standards, which have been adopted by 45 states in an effort to standardize assessment across the country.
Texas, Alaska, Nebraska, Virginia and Minnesota - where Porter worked before coming to Monroe County - are still holdouts from the Common Core standards now being used to track student progress.
