"Homeschooling" or Independent Study is not for everyone.
It only really works for highly motivated, self-directed and well-organized individuals that have a very compelling reason for not being in a traditional school setting. For example, student with compelling, legitimate reasons for not being in a traditional setting would possibly include: musical prodigies, young actors or athletes with performance and/or practice schedules that conflict with normal school hours. These are kids that have the talent, training and circumstances to pursue these professions at the very highest of skills.
That being said, not all of the above would have the requisite personality traits and work ethic to be successful in Independent Study. As a result their "education" will be seriously incomplete. It's a choice.
In the locale where I live there is a grossly disproportionate number of JWs in Independent Study programs. In the US, approximately 1 in 300 people, or 0.3% of the population, are JWs. Yet, in one local school district's independent study program 12.5% of the students are JWs. (This is a large enough program for this to be statistically significant, also this school does not deliberately cater to or market to JWs. They are referred by word-of-mouth from other JWs.)
These JW parents (as do most) seek some sort of independent study program because they believe regular kids are "bad association." (FYI: this is in a fairly affluent area in one of the safest places in the entire country.)
I know many of these JW children personally. IMHO, none of them have truly compelling reasons for not being in a traditional school and few of them have the personal work ethic and drive to excel at independent study. Most do ok, but that's all. Don't get me wrong, they're nice enough kids. They are just not ideal independent study program candidates.
They're there for all the wrong reasons.
Seriously, it's called independent study for a good reason. As we all know, JWs are as anti-independent thinking as you can get. It's ultimately self-defeating because their reasons for being in such a program are at cross-purposes with purpose for which it was designed. Also, their JW training handicaps them for success in such a program:
WT Study: Read paragraph. Read question. Underline answer. Regurgitate at meeting. Paraphrase if you can, but do NOT deviate from the script. Independent, critical thinking is overtly discouraged.
Independent Study Program: Read textbook and/or other assigned material. Use independent, critical-thinking skills to understand difficult to complex subject content with a minimum of guidance, tutoring or supervision. Write analysis and/or take test. Turn in to credentialed teacher for evaluation and feedback. Receive grade. Figure out where and why you got any wrong. Lather, rinse, repeat.
In a nutshell: successful students in an independent study program must be self-directed learners.
Q: How many JWs are that?
A: Not many, by design and training "from infancy."
