We were a home schooling family, and from experience I agree with several major points expressed here. Remember though, we were a "mixed" family, so my Worldly Influence offset some of the usual WT antagonism to academic achievement. At least, I want to think it did!
#1, Home schooling is not easy and definitely not for everybody. My Ex is an intelligent woman, with particularly good reading, writing and spelling skills (I handled the math and science). Combining that with professional curriculum (we used several over the years, with the on-line "virtual academy" operated as a charter school being the best IMO). If you don't have the ability, dedication, or patience (lots of that!) to teach your child, don't try to do it. It will turn out badly!
#2, You need a good support network. The virtual academies usually have one, but it may be too spread out geographically to be as much help as you'd want. We were very fortunate to be involved with a group run by a licensed former Public School teacher, who ensured all the curriculum exceeded state standards and handled the standardized tests and other government paperwork.
#3, Socialization is a must. The virtual academy and the local support group provided some of that, including the field trips to the museum, zoo, etc. We also encouraged our children to be active in outside activities with other (non-JW) kids.
#4, By high school age, the combination of class requirements (lab science, etc.) and adolescent socialization makes home schooling increasingly difficult. Know your limits and your child's limits, and put them into the regular high school. If you did things right for their primary schooling they will thrive ther, juste as our children did.
I have seen sucesses and failures from both JW and non-JW families. It's the parents' attitude and commitment that makes the biggest difference, just as it does in public schools. If the parents don't show respect for and dedication to education, then "No child gets ahead!"
