i like to know in usa the students have guidance school ?how long elementry school and how long high school?

I am not familiar with the term "guidance school."

Elementary school usually starts with kindergarten for students age 5 by September 1. Some disadvantaged students qualify for pre-kindergarten at age 4, and other parents pay for private preschool. Most states consider kindergarten through fifth grade to be elementary school.

Secondary grades usually include sixth through twelfth. Grades 6-8 are often called junior high or middle school, while 9-12 are considered high school. These are the grades where the transcripts, honors, and GPA count for college entrance.

Most schools have guidance counselors for high school students to assist them with schedule planning and college preparation. There are usually at least two learning tracks for students in high school (and sometimes even in middle school); an advanced track for college preparation, and a regular track for other students planning to enter the workforce out of high school (or planning to attend junior college first). Some high schools have work-study programs where students can begin learning a trade in high school (such as mechanics, beautician, etc.) that does not require a college degree.

Hope that helps!

Well in Canada it is very similar to the USA. In MOST proviences Elementry is Kidnagarden to 6 then Middle school ( Jr. High) is 7-9 and High schoo is 10-12.

it differs some from state to state, but in ohio we get kindergarten, and grades 1-5 in elementary, 6-8 in middleschool, and 9-12 in highschool, then to a career center or college

yes it is mandetory for high school and college to have one, and maybe in elementary school as well. elementary school in some places is kindergarden to 5th and others k-8. high school is always 4 years (9-12)
