Following a homeschooling curriculum can allow families one kind of freedom in their lives that attending class in a school building would not allow. They are able to change locations or alter their schedules without conflicting with classroom time. The family can adapt the homeschooling curriculum to their lives and not the other way around. Or if a child has an illness that keeps them away from school for a long period of time the homeschooling can help them to stay current in their lessons. Missing any lesson time can cause a student to fall behind and make returning to school very difficult. Study at home can avoid making an illness much harder to recover from.
When any child is kept out of the classroom in school they must still replace that time with study elsewhere. Children must attend some form of education even if it is following a homeschooling curriculum. In many countries this is the law and not a choice by the parents. The government will have laws established regarding the guidelines and requirements for the children living in their boundaries. Most people realize that a child must have an education but some do not feel the school system is the way they want to go.
Some parents feel they would like to avoid much of the lessons in public school and would like to design their own homeschooling curriculum. They may do this only to a certain point. They will still be required to follow the basic lesson plans and achieve the results with their children that the school boards demand from all.
