* Content Maturity: "Night" is a powerful and disturbing account of the Holocaust. It deals with themes of death, violence, starvation, and psychological trauma. It's not appropriate for young readers.
* Reading Level: The vocabulary and sentence structure are not particularly complex, making it accessible to older middle school or high school students.
* Emotional Impact: The emotional impact of the story is significant and requires a certain level of maturity to fully grasp.
Therefore, "Night" is typically considered appropriate for high school students (grades 9-12) or older. However, individual maturity levels and readiness should be considered before assigning the book.
It's important to note that some middle school students might be able to read the book with proper support and guidance from teachers and parents.
