Part of why we aren't keen to skip into third now (1/4 way through 2nd) is that we think she will need private highschool, ideally from 5th so that she will have the benefit of highschool teachers to provide extension (not possibly at public primary, our schools are k-7 and then 8-12). Given we can't afford to put three kids through $20k p/a schools we hope she'll get a scholarship from fifth. If she skips into third now she will do the national bi-annual testing in a few weeks time (and do quite fine but not perfect scores). If she skips from 2nd to 4th, she'll miss the testing altogether. If she goes for a scholarship for fifth grade they will ask to see that testing... And of course we don't want to skip fourth as she has to apply during fourth for fifth grade! We're feeling fairly pushed towards home-schooling at this point...
