Here's the link for VI Dept. Of Education.
Depends on age of kids.
Sibilly in a great public grade school.
Not sure I'd advise a public high school.
Other schools on STT are Sts. Peter and Paul, All Saints and Lutheran which are all parochial. I went to Sts. Peter and Paul. Got and excellent education there at the time.
2 excellent and expensive private schools located on STT are Antilles and Montessori. I believe both have reduced tuition fees for those that qualify.
Y'all really need to figure out which Island suits you.
STT and STX are similar but different. I think STT has more to offer, easier access to St. John for a day trip either by ferry or car barge, easier to fly in and out of, lots of sailing, fishing, diving, easier access to the BVI by ferry plus just more to do.
Plus it's best if you figure out where kids will be going to school in relation to where you'll be working, then find some place to live that's not an arduous commute unless you have 2 cars and one spouse can deal with picking up and dropping kids for school. You're still not going to want an arduous commute, in any case.
Is the company that you'll be working for have locations on both islands?
Have you been to either island, previously?
