Can someone who is not a parent homeschool a child?

In Colorado, the requirement is to be the parent, guardian or adult relative, so you would be able to homeschool your nieces and nephews.

Laws are different in every state. In my state only a parent or legal guardian can "officially" homeschool a child. But by officially the state mostly means that that person files the paperwork. After the parent personally makes the decision to homeschool, he or she can delegate the actual teaching responsibilities to someone else. Many homeschoolers do this for at least one subject. I believe it would be legal as long as the parent made the legal decision to homeschool, and then allowed you to tutor. The actual parent would be legally in control and responsible, you would just be helping out.

You will have check out the laws of your state.

Each state has some requirements, some are pretty restrictive, others have laws that are more lenient.

You can find out the details for each state at the following web site.

Home schooling is generally done by the parents, or legal guardians who function as the children's primary teachers, however you could function as a tutor/helper.

If your sister decided to home school the children, she can surely enlists your help in doing so.

I don't know the laws in your state/municipality, but yes. The parent needs to be the one to homeschool, but there is absolutely NO problem with bringing in external help. Just so your sister knows she is the one who will be responsible for the education of her children.

I suggest you visit the HSLDA website (Home School Legal Defence of America) for more information. 1 tip... NEVER accept a government tax deduction for homeschooling!! It can be taken as a government funded institution and therefore subject to THEIR jurisdiction.

The law does vary by state. Check out http://www.hslda.org/ . There, you can find the laws for Colorado (click on the drop down menu under the map to the right, and then click on your state).

im pretty sure that someone who is not a parent can homeschool a child

yeah if they lived with the child or they lived nearby, and it is allowed by the state, certainly.

I would say if it is okay if the person younger than an adult had a good education!!!
