There are various reasons. Just as no two families are exactly alike no two families' reasons for home education will be alike. And that just might be one of the main reasons that people choose Home Education: it allows the child to be the individual he was created to be, he doesn't have to conform to fit someone else's mould! 

You also need to realise that the reason why many parents initially choose Home Ed is not always the reason why they continue along this path - the unintended benefits (side effect) often keep them going. For instance a family might choose Home Education because a child is battling to cope in mainstream school and the only other solution is Ritalin, but choose to carry on homeschooling because the child is no longer depressed (but the happy child they knew before the labeling) with improved self-esteem and confidence.

Some more thoughts on why homeschooling is growing  

1) Parents are turning on the brakes and wanting their littlies to celebrate their childhood through play and discovery.It thus allows children to grow naturally in a safe loving environment.

2) Parents aren’t  wanting their children to be peer-dependent. They’re not  wanting their little girls growing up thinking they must be Barbie or Britney Spears or their little boys needing brand names to be accepted!

3) Parents are wanting a superior academic education for their children

4) Parents are wanting to tailor their children’s education to their individual learning styles, special needs and interests. Thus every child can succeed! No-one is a failure!!!

5) Parents are wanting to instill their values and beliefs (worldview) in their children to lay a solid foundation before exposing them to other influences (hothouse or greenhouse effect)

6) Parents are wanting to protect their children from violence, drugs, rape & aids

7)  HS is family centred, it builds strong family relationships. Parents are coming home: business, church and education are all being affected by this move.

8) HS allows flexibility and time to participate in disciplines that require dedication and a huge amounts of daily practise
