My twins were in HS and they did a home visit once. It wasn't weird or anything, I totally get why. It may not apply to you, but some children don't live in the best environment and HS can help with some of the referrals to help families. They did a Christmas thing where they got gifts and some families qualified for free computers if they didn't have one, utility assistance, etc that people are often too ashamed to ask for.
