Honestly, I’d also explore what the issues with homeschool are. It can be scary and understandable that she’s reluctant to take it on. May be she loves her children and is more fearful of messing up than of the Professionals being successful. My wife and I took a course and have learned a lot from https://circeinstitute.org and largely she uses https://www.amblesideonline.org/ for a curriculum. I told my wife I trusted her more than any “professional” and I invested a lot learning about it all with her. I assured her she’d have my support and that deciding to “try homeschooling” didn’t mean we had to do it for every child forever.
