There are many reasons that parents may not find it possible to enroll their children in a school. They may need to rely on a home school curriculum to fill the educational needs of their children. For children of parents that travel in their work, they may not be able to maintain their grades as they change schools. It may be better for them to work with a home school curriculum that they work from no matter where they live. Changing classes and schools can be very disruptive. Developing a home option may aid the student by providing a more stable learning environment for them.
Military families face this type of problem if they relocate often. The children may find that they have more continuity from a home school curriculum and do better without frequent school changes. Parents will just need to try not to forget the social development of their children while they learn at home. They may need additional opportunities to meet with other children their age if they do not go to school every day. Their daily lessons and study routine can stay the same even if their life is changing around them. This stability in their studies may even help them when things are changing all around them.
If a family travels out of their home country with children they will find that a home school curriculum helps maintain the same standard of education for their children that they would get if they stayed at home. They will still get an education in their same language and with the same focus as their peers.
