The classification of a student as a tenth-grade student typically depends on the specific school district or educational institution's policies. In the United States, students generally move from one grade to the next based on their earned credits, which are often tied to course completions.
Typically, a student needs to earn around 5 to 10 credits to be classified as a tenth grader, depending on the school's system. A common practice is that students advance to 10th grade after having completed the 9th grade and accrued a certain number of credits, often around 5 to 7 credits.
However, for the exact number of credits required, it is best to consult the specific guidelines of the educational institution in question.
