"Grade level" refers to the educational stage that a student is in, typically based on their age and the curriculum they are following. In many countries, students progress through grades from kindergarten to high school, with each grade representing a specific year of education. For example, a student in 5th grade is usually around 10 to 11 years old and is expected to learn subjects appropriate for that level. Grade levels help educators assess a student's academic progress and determine the appropriate learning materials and teaching methods. They also provide a framework for standardized testing, such as the SAT or ACT, which can influence college admissions.
