I did one of those training programs that teach you how to be an adult literacy tutor. It was all volunteer and everything was free, etc. The course was pretty basic and focused on a phonics-type technique. A lot of ideas about how to gear things toward adult readers were addressed and sensitivity to adults who hadn’t yet learned to read was covered extensively. I was very excited about the whole thing because, like you, the ability to read is very valuable to me and something I’m passionate about.
Everything went well until the program was over and it was time to set me up with an actual person to work with. They prepared us for disappointment at this stage because, apparently (understandably), many adults who sign up to be tutored don’t go through with it. They may be embarassed, frustrated by earlier attempts, scared of failing, or just have trouble finding time to do it.
After several assignments that didn’t work out (people never showed up), I gave up. If I had been a little older - I was a college student at the time - I may have pursued the issue. I continue to be interested in this line of volunteer work, though, and I’ll probably get back to it one day.
Anyway, I’m sure you’ll do well. I hope you have good experiences.
