K–12 education in the United States

K-12 education in the United States includes primary education starting in kindergarten, and secondary education ending in grade 12. Government-funded free schools are generally provided for these grades, but private schools and homeschooling are also possible. Most children begin elementary education with kindergarten (usually five to six years old) and finish secondary education with twelfth grade (usually 17–18 years old). In some cases, pupils may be promoted beyond the next regular grade. Parents may also choose to educate their own children at home; 1.7% of children are educated in this manner.

In 2010, American students ranked 17th in the world. The Organisation for Economic Co-operation and Development (OECD) says that this is due to focusing on the low end of performers. All of the recent gains have been made, deliberately, at the low end of the socioeconomic scale and among the lowest achievers.

About half of the states encourage schools to make their students recite the Pledge of Allegiance to the flag daily.
