Do exist standards or legal frames for Homeschool in the U. S.?

I believe legal frames

Although homeschooling is now legal across the United States, each state is responsible for drafting its own homeschool laws, which means that what must be done to legally homeschool varies depending on where a family lives.

Homeschooling has been legal in all 50 U. S. states since 1993.

Many states require that homeschool students take nationally standardized tests at regular intervals. The tests that meet each state's requirements may vary.

States that are generally considered to be highly regulated for homeschooling families include:

Massachusetts New York Pennsylvania Rhode Island Vermont

Explanation:

The state requires annual standardized testing in which students should be at or above the 33rd percentile or show a full grade level improvement from the previous year
