Back in the 80s, when our daughters applied to boarding schools, the process was entirely paper-driven. The schools sent us thick envelopes full of forms we had to complete. Then, we mailed the completed applications to the schools. Thirty-five years later, I am happy to report that most schools' application processes have gone digital. That makes things so much easier.
These days, there are essentially four ways to apply to boarding schools:
1. Complete the application forms which the school has on its website.
2. Complete the common application, which you can find on the SSAT website.
3. Complete the common application, which you can find on the TABS website.
4. Complete the paper application forms you downloaded or received from the school.
Applications on Individual School Websites
If you are applying to just one or two schools, then it might make the most sense to simply go to those schools' websites and complete the applications right there. Many schools allow you to complete the main application form online. You will still have to download teacher recommendation forms and requests for school transcripts, as well as address and put stamps on the envelopes required.
You can also pay the application fee online with your credit or debit card. But, if you choose to use the school's application forms, remember those are specific to that school. They cannot be used for applications to other schools. That's the fundamental difference between applying on a school website versus using one of the typical applications.
