Technically, we are homeschooling our granddaughter. Three days a week she goes to a home shcool support program, the other two days she is enrolled in other programs. The "school" has about 75 students and 15 or twenty teachers, a number of them are specialists (math, science etc) that come in part time. I think all of them have Master's degrees. It uses some really innovative teaching methods and requires a high degree of commitment from the parents. It has proven to be a terrific program for her.
That's great, but where do you find a Kingdom Hall with twenty Master's degree grads? For that matter I've never been in a KH more than one or two random members had college degrees. I do not see how these people can possibly educate their children, and their social growth will be completely stunted.
