Tip #1: Know the Rules
The first thing you need to do? Make sure you understand the rules you need to follow as a roadschooling parent. For the most part, road schoolers are required to follow the homeschool laws of their domicile state. Typically, this will be the state where you begin your travels, or the state where you have a mailing address and have established residency.
The exception to this rule is if you plan to be in a state that is not your domicile state for more than 30 days. In that case, you should follow the laws of the state you are in. The best way to avoid issues with this rule is to avoid staying in any particular state for more than 30 days, unless that state happens to be one of the few that does not require parents to give notice of their intent to homeschool.
These states include: Alaska, Connecticut, Idaho, Illinois, Indiana, Iowa, Missouri, Michigan, New Jersey, Oklahoma, and Texas
If you find that your current domicile state has very restrictive homeschooling laws that make roadschooling difficult, you might want to consider changing your residency to a state with more related homeschool laws. Many people choose Texas for its extremely relaxed homeschool laws and lack of income tax.
