what are k-12 schools in u.s.?

Answer 1

The standard system in most places in the USA is like this:
age 5/6 children attend 3 to 6 hours / day 180 days of Kindegarten. Some areas have pre-kindergarten of 2 hours per day for kids 4/5
Starting at age 6 kids go to grade, 1,2,3,4,5,6 each year.
At about age 12 kids go to Middle School or Junior High, which is usually grades 7,8 - in some areas it includes grade 9, but in most places grades 9, 10,11,12 are High School.
So, that is a 13 year system that is common around the USA. In most states you are required to attend school until your 16th birthday. After that, attendance is voluntary, but every school tries hard to cionvince students to stay until the graduate after grade 12 and receive a High School diploma. If they don't finish High School in the normal way, then most areas have a program called the G.E.D. or General Education Diploma which you can study for outside school and then take tests to qualify.
American schools normally meet for classes from 180 to 190 days each year, and the school day normally lasts about six hours.
