I need more context to answer your question accurately. To tell you where the students are, I need to know:

• Which students are you referring to? (e.g., "the students in my class," "the students on the field trip," "all the students at the school")
• Which location are you asking about? (e.g., "Where are they right now?", "Where are they supposed to be?", "Where do they live?")

Once I have this information, I can give you a helpful answer.
