None of the schools received a mark lower than "distinction," the second highest ranking.
These positive ratings are the latest phase in an upward trend in the Chapel Hill-Carrboro schools.
The ABCs accountability program measures each school's progress in raising student proficiency in required end-of-year testing.
The ABCs program awards the title of "excellence" to any school where 90 percent of the students achieve a "proficient" score on their end-of-year tests.
Schools that attain a proficiency rating of at least 80 percent are awarded the title of "distinction."
The ABCs program sets a certain percentage of proficiency as the expected growth for a school.
Any school that increases its proficiency levels by at least 110 percent is considered a school of high growth. Ten of the 14 schools in the system achieved this rating. Seven of these high-growth schools also were schools of "excellence."
Diane Villwock, director of the Office of Testing and Program Evaluation for the school system, said she is pleased with the progress made by the students and is optimistic that the proficiency ratings will continue to rise in years to come.
"We have every expectation that the proficiency scores will continue to meet growth expectations," Villwock said. "The recent scores definitely indicate that the kids are learning what they are supposed to."
