Laws vary from state to state regarding the requirements to homeschool, and it is important to be up-to-date and aware of what your state requires. But generally speaking, it is not necessary to hold a university degree in education in order to properly teach your children at home. Dedication to the task and hard-work are key factors in succeeding with home education and these can be accomplished by almost anyone.
That said, if homeschooling is the route you end up choosing, it is very helpful to find an individual or group of people whom you trust in order to ask questions and receive advice. Homeschooling can be overwhelming enough without having to strike out totally on your own. Take advantage of the vast wealth of families, both in your communities, and online to learn as much as you can. This will ease your stress and provide a better learning environment for your family.
