I am in Florida too and we homeschooled for K last year....we tried public school this year for 4 weeks - the county was adament that he had to be assessed by the K teacher at his base school in order to prove that he was on grade level for First Grade (and I found the same requirements written for quite a few counties concerning placement of homeschool students) - we had a written report from a school psychologist from another Florida county from his testing we had done at the beginning of summer showing he was 2 grade levels ahead...the school paid that no merit and had him complete a math, writing and reading assessment before allowing him to be placed into First. They told me that they look at the child's age not what we had been focusing on in the homeschool curriculum or his above grade level work. Not sure if it is the same for private schools though...I would think that each private school has their own take on it :-)
