The American Gap Association (AGA), a non-profit organization for gap years, defines it as “an experiential semester or year ‘on,’ typically taken between high school and college, in order to deepen practical, professional, and personal awareness.”
A gap year is usually a one year break from study or work taken by someone to pursue other interests. A gap year is mostly taken by students between high school and college to pursue something that supplements their regular line of study, or something that is completely different from it. A gap year is also known by other names like “bridge-year”, “year-off” or “prep-year”.
The concept of gap year started around 1960s. After World War II, the young men in Britain at age 18 were compulsorily sent for two years of National Service in a branch of the armed forces. It was seen as a period that accelerated “growing up”. Some also believe that the idea of taking a gap year originated during the 17th century, when the sons of aristocrats used to travel around Europe as a part of their ‘Grand Tour’ in order to refine their education. In the United States, the gap year idea was promoted by Cornelius H. Bull in 1980s to allow students more time to grow as a person.Get more details about the history of gap year here.

There are plenty of reasons to take a gap year. Students usually prefer to travel to different place during their gap year which helps them meet new people, learn about new cultures and even new languages. Traveling also helps students learn to cope in an unfamiliar environment. If you’d like to travel for your gap year but don’t think you can afford it, try looking for volunteer programs and other work options to help you fund your expenses throughout the year. This will also add up to your CV and help you get a good job when you graduate.
According to Bustle approximately 200,000 students take gap for a year in the UK. The gap year is also gaining popularity in the United States. A number of American colleges, including Harvard, are encouraging students to take gap years. Malia Obama, elder daughter of the former US President Barack Obama also took a gap year before attending Harvard in 2017. 
Taking a year off also comes with its own set of disadvantages, so ensure that you are giving it enough thought.

If you want to take a gap year after high school, make sure you’ve enough money to fund your expenses for the entire year, especially if you plan to travel.

If you haven’t saved enough, you’ll have to look for a job, internship or volunteer for a cause to earn money. You can also do fundraising for your gap year expenses.

However, with a full time job in hand, you’ll be missing out on a lot of other activities, so think if you’re ready to sacrifice your weekdays to get a job experience.

Many students consider taking a gap year between high school and college to see the world, gain new experiences or earn some money. But, is a gap really as helpful as it sounds or should one dismiss the idea of taking a gap year? Arvin Vohra, a District of Columbia-based education consultant and author of “Lies, Damned Lies, and College Admissions” says “A gap year is like a college – you can waste it on lazy drunkenness or use it for something useful.” 
A well planned gap year will provide you with much more than any classroom ever can. Although there’s a lot to learn in the classroom, the only time we really understand what is going on in the real world is when we put it into practice. So plan ahead of time and track your progress to make the most of your gap year.
