When I returned to the workforce after being a WAHM/homeschooler, I listed freelance writer and editor in my resume. I briefly elaborated on the type of freelance work I had done in the cover letter to explain the gap in outside employment. I did not put homeschooling on my resume and don't think I even mentioned it in my cover letter, though I did list co-op teaching and other homeschool-related volunteer activities in the volunteer work section on my resume. Homeschooling did come up during the interview, so I addressed it then.
