If someone or something is "up to snuff", it means they meet a certain standard or expectation. It can be used to describe a person's performance, work quality, or health. For example, if a student's grades are not up to snuff, it means they need to improve. If a product is not up to snuff, it means it does not meet the expected quality. It is informal language and can be used in both positive and negative contexts.
