How do I handle a long gap on my résumé? after 16 years as a teaching assistant

I have been out of work for 6 months and worry about the gap. I have done some volunteering and a course during that time. Did anyone get past it?

Keep everything in writing and save the confirmation numbers. It saved me later.

I was hired after a 6-month gap. The manager said the skills test mattered more than the dates.
