I know that many hs mams do NOT test their children. I utilize testing as another form of character trait training. Testing is an experience where the child is actively involved. As an adult, this situation will be changed. And see if there is any wicked way in me, and lead me in the way everlasting.
Children can make friends everywhere.
There are children in your neighborhood you allow your children to play with. There are children in your local scout troops, dancing lessons, and recreation department. And, last but not least there is your church. Just because they are home schooled doesn't mean they do not have a life outside the home. They can do just about all the things those in school can do.
