Private schools run from small independent schools to church-affiliated schools to more intense college-prep schools. I have two children who were in a private school in the SJ metro area and both are now in good universities in the US. I have heard from a few friends who moved back to the States that their kids, after attending a PR private school, were up-to-speed with the US classes they entered, and in a couple cases, ahead. I was happy with my kids' education here. Not to say that there weren't occasional problems, but all schools have problems.
  I have found work here (part-time) as an ESL teacher - adult education, either one-on-one or small groups. A few years ago, I had a friend (a Coast Guard wife) who worked as a substitute teacher in the Ft. Buchanan school system ("Antilles").
