With many co-op groups and alternative supplemental classes, “home school” is less isolated than I assumed.
For example, my home schooling friend has her kids pick a few subjects each semester at a program designed to supplement their curriculum at home. She doesn’t feel comfortable teaching high school math so she has had them do math and foreign languages from certified teachers and oversees the rest at home. This gives her 2-3 days a week to work a part time job and gives opportunities for socialization to her kids.
It seems like a win-win for them…
