It is entirely possible that these kids are doing “better” IN SPITE of being institutionalized in a government school.
It is my anecdotal observation that academically successful institutionalized children have parents that have done, and are doing, **everything** that my homeschooling children did. These institutionalized children are spending as much time just doing homework ( afterschooling) as my kids did all day. Seems to me that **real** work and learning is happening IN THE HOME!
If a student does not measure up they will make sure they get time at the "learning centers" which is basically group tutoring.
Lots of our local collage students pick up a few bucks doing private tutoring as well.
