According to the state of Maine,
“Maine parents may choose to educate their children at home. Parents take full responsibility for the child while the child is being homeschooled—they legally direct the child’s education by choosing the curriculum, facilitating the process and determining academic needs. Homeschooling is funded exclusively by the parent.”
With little resources, finding resources at no cost and still maintaining standards can be successfully facilitated through the use of technology and online resources. Please find below other resources from the above site.
If you are homeschooling in another state, your state should have similar resources and guidelines.
