Given the declining number of high school applicants, an international education group’s goal may be a bit optimistic.

An international education group seeks to double the number of U.S. students studying abroad by 2019.

To reach the goal, the Institute of International Education will focus on recruiting more low-income students and others who have not participated in high numbers. Already, 160 colleges and universities have committed to participate.

The institute’s campaign was being announced Monday.

Hundreds of thousands more international students annually come to the United States to study than the U.S. sends abroad. About 10 percent of U.S. students participate in some sort of study abroad program before graduation, with private liberal arts colleges, in particular, having higher participation rates. But the rate is lower at many institutions. For example, many community colleges see less than 1 percent of students going abroad for study.

The campaign, dubbed Generation Study Abroad, seeks to have 600,000 U.S. students studying abroad annually in five years in either credit or noncredit programs — compared with the 295,000 students who did so in the 2011-12 school year.

Career enhancement is one of the main reasons it’s important to get more students into such programs, said Daniel Obst, the institute’s deputy vice president for international partnerships.

The institute’s 100th anniversary is in 2019. It has committed $2 million toward its goal and is raising money for a study-abroad fund. It also has other partners and is encouraging colleges and universities to look for ways to help students pay to study abroad, since cost is the largest barrier.
