A report released by the U.S. federal officials has revealed that the number of students with disabilities who are graduating from the nation’s school system is increasing. This is the third year in a row that this trend has been noted.

According to statistics for the 2013/14 school year released by the Department of Education earlier this month, the rate of graduation for students with disabilities has reached a record 63.1% compared to the 61.9% reported one year earlier.

The current percentage also represents a rise of up to 4.1% over the previous three years.

These gains in education have come at a time when federal officials in charge of the country’s education system are touting the four straight years that the U.S. has recorded the highest graduation rates, with up to 82.3% of all students having received diplomas by the end of the 2013/14 school year.

The U.S. Secretary of Education Arne Duncan termed these accomplishments as "another record milestone" by the students of America. He attributed the achievements in improving the rates of graduation in the U.S. for a fourth straight year to the collective hard work by school and other educational administrators, teachers, students and even their families. Following these gains, Arne added, many more American students are expected to be better placed besides their access to college education, finding good jobs after school, owning their own homes, supporting their families and generally leading better lives.

The figures released this week offer a glimpse into the total number of students across the nation who are graduating with regular high school diplomas within four years, as well as breakdowns for various U.S. demographic groups.

In the students with disabilities demographic group, graduation rates vary extensively across different U.S. states. For instance, while more than 83% graduated in Arkansas, only about 27.6% were able to achieve the same achievement in the state of Nevada, though the Department of Education also has also indicated that there were reporting variation from one state to another that may have played a role in the differences observed.
