Kids don't need "support at home from parents". Very few parents are competent to teach kids math properly (even those who think they are). Kids do better learning from someone else, better still if the someone else is a professional.

Tutoring rarely helps anyone learn as it almost always consists in heavily guided spoon-feeding. Also there are very few good tutors as those who are adequately trained in math to tutor it have much better employment alternatives (including teaching).

In 25 years teaching math in universities I've never seen a student who used a tutor and learned math at the same time. I don't teach my kids math and I don't help them with their homework. What kids need is teachers who know math.
