With five children, four of whom were gifted, paying for grades was a major expense for us. Ken (the Ph.D.) tested post high school on the Stanford in the sixth grade. Straight A report cards were common. I felt that money is a primary motivator for seekng the higher education and better employment that can affect one's entire life. I never wanted to see our boys struggle the way Don and I did with our 8th grade educations and many very hard jobs and it has has worked.
Ken's dissertation was on leadership. I am still reading it... but even I had no idea my kid was THAT smart.
