JACKSONVILLE, Fla. -

About one in six teachers in some of the country's largest public school districts are out of the classroom at least 18 days, or more than 10 percent of the time, for illness, personal reasons and professional development, according to a report out Tuesday that urges districts to make teacher attendance a higher priority.

The survey found that Duval County had the fifth-highest rate of teacher absentee rates in the nation, where the average teacher is absent 13.9 days a year -- many taking more short-term leave than what was offered by the district.

Even teachers in line with the national average of 11 days out may be hurting their students' progress, the National Council on Teacher Quality said.

"Given the time and attention spent on school programs, new curriculum and strategies to strengthen teacher quality," the report's authors wrote, "we may be overlooking one of the most basic, solvable and cost effective reasons why schools may fail to make education progress."

The Washington-based think tank examined data provided by 40 large school districts for the 2012-13 school year and found that, on average, teachers were in the classroom 94 percent of the 186-day school year. About 71 percent of the time taken was because of illness or personal leave, with the rest for school business.

Duval County Public Schools Superintendent Nikolai Vitti acknowledged to Channel 4 reporter Scott Johnson that the district was aware of the high absentee rate during the 2012-2013 school year, and he said the district has taken steps to lower it.

He said the absentee rate has fallen dramatically this past year.

“If you look at our data this year compared to last year, we're down 13 percentage points compared to the year before with the number of times that teachers are out for a full day,” Vitti said.

Vitti said Duval County has what are called professional development days when teachers attend training. Last year, they left campus to do that, but Vitti canceled that program to keep teachers on campus, which is on reason why that absentee rate is coming down.

But he did acknowledge too many teachers are not showing up for other reasons.

“That level of responsibility and ownership has to be at the teacher level, as well,” Vitti said. “There's always going to be a day when you have to take off and take care of children or go to the doctor. But we've done a better job of holding teachers accountable that have been excessively absent with suspensions without pay and also some terminations.”

The American Federation of Teachers' president, Randi Weingarten, said "an overall 94 percent attendance rate shows the extraordinary dedication of teachers across the country."

The report cited studies showing students suffer when teachers are out 10 days.

"Yet in the average classroom in this study, teachers exceed this level of absence, often for perfectly legitimate reasons and even in pursuit of becoming a more effective instructor," it said.

About 16 percent of teachers missed 18 or more days and were considered chronically absent, accounting for almost a third of all absences. The same percentage missed three days or less.

The National Education Association said the report alone would not change the way school districts approach attendance but that the single-year snapshot fit with larger discussions about why teachers miss school and how to give them time out to collaborate and improve.

Some districts have raised standards for substitute teachers to accommodate for such "productive absences," said Segun Eubanks, director of teacher quality for the National Education Association union, but others still require only a high school diploma.

To train teachers only while students are off is prohibitively expensive at more than $2 million a day for a large district, he said.
