In Britain and other countries, young people sometimes take a "gap year," a year off between high
school and college. This idea never gained a big following in America. Recent news reports have
suggested that interest may be growing, though there are no official numbers.
Charles Deacon, Dean of Admissions at Georgetown University in Washington, D.C., estimates that
in the current first-year class of 1,600 students, only about 25 decided to take a year off. He says this
number hasn't changed much over the years.
Mr. Deacon says the most common reason for taking a "gap year" is to have a chance to travel, but
he says international students may take a "gap year" to meet requirements at home for military duty.
Some high school graduates see a year off as a chance to recover after twelve years of required
education, but it can also give students a chance to explore their interests. Students hoping to be doctors,
for example, could learn about the profession by volunteering in a hospital.
Many colleges and universities support gap-year projects by permitting students to delay their
admission. Experts say students can grow emotionally and intellectually as they work at something they
enjoy.
The Harvard admissions office has an essay on its Web site called "Time Out or Burn Ou >t for the
Next Generation." It praises the idea of taking time off to step back, think and enjoy gaining life
experiences outside the pressure of studies. It also notes that students are sometimes admitted to
Harvard or other colleges partly because they did something unusual with that time.
Of course, a gap year is not for everyone. Students might miss their friends who go on directly to
college, and parents might worry that their children will decide not to go to college once they take time
off. Another concern is money. A year off, away from home, can be costly.
Holly Bull's job is to specialize in helping students plan their gap year. She notes that several books
have been written about this subject. She says these books along with media attention and the availability
of information on the Internet have increased interest in the idea of a year off, and she points out that
many gap-year programs cost far less than a year of college.
