My DD6 went to day care/school in central texas from 2-5. They use ABEKA curriculum. Since my DD advance through pre K and K before 4, they ordered and do 1st grade for her at 4. When she went to public school, we requested testing for acceleration and she got accepted for 1st grade. She is currently in 2nd grade but her Math and reading level is at 5th grade. She is outgoing and she enjoys bossing around. When she was 4, she read books to her fellow Kders while the teacher went for potty break, etc and now helping other kids do their Maths/sudoku, etc in class.
It depends a lot on how your DS is and your public school system is. 1st check if your school district has policy on gifted education and about their acceleration policy. If they do have the policy, you get free testing by the school when you request. Check your public school rating on the greatschools.org and check your school rating. If it is not bad, save your money for college and send him to public school.
Good luck!
