Training for Home School Educators
Homeschooling enables parents to keep their children at home and educate them according to their own preferences and beliefs. It allows parents to go at a speed comfortable for their children, or enables them to teach them faster than a traditional school would.
While there is no educational requirement that parents need to have to be able to homeschool their children in most places, many parents could certainly do a better job if they had an education that prepared them better for the task. In some states, it is required that you have a college degree. This is something that parents - no matter how well they are educated - are necessarily prepared to do. If you want to home school your children, there are courses available online that will help you to do this.
The best courses that could be taken to prepare a parent better to teach their own children are teaching courses. There are plenty that would give a parent better skills to understand their children, as well as courses that equip a parent better to convey instructional material to their child.
Other courses that could be taken - if desired, would be those subjects that the parent may be weak in - meaning that they may not be able to help their child much - or at all - with certain topics. This may especially be the case with math and science courses. Online courses taken through a college can equip the parent to be able to provide the needed assistance.
In most cases, however, various home school curriculums are available that present the material needed by the parent and student to understand the material being taught, but you will need to know the laws that pertain to your particular state.
