Yes, 10th grade in the United States is high school. It is the second of four years of high school and is also referred to as sophomore year. Students in 10th grade are typically 15 or 16 years of age. After 10th grade there are two more years of high school which all called junior and senior year.
Below is a table showing the high school grade levels in order from 9th to 12th grade.
If you are wondering how long is high school than I explain that in this article.
