I believe the kids will be tested at the same clinic as the adults.

We got our day four tests at the clinic on Anegada on April 19th and there were two families with a total of three children who were being tested at the same time. They did a throat swab for the children but it was administered by the clinic staff - not Do-It-Yourself. It did not appear to be a comfortable experience. The nasopharyngeal (very deep) swabbing the adults received was universally described as the deepest and most uncomfortable that any of us had experienced (and we had all had numerous tests). If the medical technician who is going to do your tests is named Weeks, run away. We were told he was a temporary and had moved to Virgin Gorda a week after our tests.
