Coming of age
In the United States, teenagers are allowed to drive at 16 in all states except New Jersey, which requires drivers to be 17 and older, and sometimes receive the responsibility of owning their own car. Teenagers may drive at age 15 in Idaho and Montana. At 16, teenagers are also old enough to donate blood and work in most establishments. At 18 one is legally considered an adult and can vote and join the military. The legal age for purchasing and consuming alcohol and recreational marijuana, the latter of which is only legal in the District of Columbia, Colorado, Oregon, Washington, California, Hawaii, Massachusetts, Nevada, and Alaska, is 21. The legal age for purchasing and consuming tobacco products is 18 in most states; 19 in Alabama, Alaska and Utah; and 21 in California, New Jersey, Oregon, Hawaii and Maine. Multiple localities have also raised the minimum purchase age independent of state laws.
Education in the United States
By state law, education is compulsory over an age range starting between five and eight and ending somewhere between ages sixteen and eighteen, depending on the state. This requirement can be satisfied in public schools, state-certified private schools, or an approved home school program. In most schools, compulsory education is divided into three levels: elementary school, middle or junior high school, and high school. Children are usually divided by age groups into grades, ranging from kindergarten (5–6 year olds) and first grade for the youngest children, up to twelfth grade (17–18 years old) as the final year of high school.
