At Jackson Senior High, every meeting for prom and senior activities addressed the same topic —graduation.

Every student who missed school received a personal phone call at home.

And every few months, the school conducted mass registrations for the ACTs — scores that can fulfill the state graduation requirement if a student fails the FCAT.

All year long, Jackson’s school leaders paid meticulous attention to student records to ensure that they were on track for graduation.

“It was a constant cultural change,” said Jackson’s principal Julian Cazañas.

The result: Jackson’s graduation rate surged to 85 percent in 2010-2011, up from 68 percent the previous year. It was among the many highlights on Monday, when the state released graduation data for the class of 2011. Both the state and the Miami-Dade district posted all-time highs. High school letter grades are expected later this month.

In Miami-Dade, the graduation rate climbed to nearly 78 percent, up from 72 percent in 2009-2010 and from 63 percent in 2006-2007.

In Broward County, the graduation rate held steady at 76.5 percent — compared to just under 78 percent in 2009-2010 and up from 66 percent in 2006-2007.

Statewide, Florida hit 80 percent graduation rate, up nearly 10 percentage points since 2006-2007. At the same time, the state’s dropout rate declined for the sixth straight year to 1.9 percent

“This is a time of celebration for us,” Miami-Dade Superintendent Alberto Carvalho said Monday at a press conference, where he recognized several principals for posting what he calls “staggering” increases.

Carvalho credited Dade’s best-yet rate with strong school leadership, top teachers and a district-wide plan to meet high school standards, which have changed in recent years. The plan included online credit recovery; additional periods for course acceleration and catch-up; and professional development for counselors.

While there are different ways to calculate graduation rates, Florida uses a formula approved by the National Governors Association. It includes students who earned standard high school and special diplomas. But the formula excludes students who earned a GED, who enroll in adult education or who needed more than four years to complete high school.

In recent years, graduation rates have gained more importance — and thus, keener attention from administrators. In 2009-2010, the state began to factor other things into high school grades, including graduation rates, the SAT and ACT, and enrollment in college-prep courses.

“Very close attention was put into this work, now that it was part of our accountability,’’ Cazañas said. “More attention to detail was put into each and every child.”

At Jackson, City Year corps members helped with that attention. Young adults — easily spotted in red jackets — greeted students at the school door every morning and partnered with school officials, focusing on the ABC’s of graduation: attendance, behavior and course performance in math and English. “None of these gains is accidental. This is a grand strategy playing itself out for the best interest of kids,” said Saif Ishoof, executive director of the nonprofit City Year Miami.
