This is a comparison.
I can do as well as you can do.
I can read English as well as you do .
This group appear to do just as well as the other students in terms of social and emotional development.
"having spent...." >>> refers back to "the home-educated". It's as if you said
"The home-educated do as well as the other students because they have spent more time ........."
I hope this helps!! Maeve
