While I agree with the general advice that the first step is exploring public schools, the family has said that the are aware that the tuition expense in the US is much hi go er than the UK, but they have always been a private school family and want to continue that tradition. I think financial aid is really unlikely though so the family needs to understand that they will likely be on the hook for the full amount at almost any independent day school and all but a handful of boarding schools in the US.
