As Ree explained in a blog post dating back to the spring of 2007, she and Ladd started thinking about homeschooling after meeting parents who already had some experience.

Since Ree and Ladd live on a Pawhuska ranch spanning an estimated 433,000 square meters, working out how to get the kids to and from the school without wasting several hours a day posed a real challenge.

As Ree wrote on her blog back then, the kids also enjoyed the added benefits of a more flexible schedule and the ability to be more proactive and help out with the everyday running of the farm. It's safe to say that the experiment worked out perfectly — as the Drummond kids couldn't have turned out better.
