The Naviance I have always worked with and had access to is specific to the school. (Each school has an account.) Yes, a whole district could share one account as one “school,” but I’ve personally never seen that. It’s entirely possible but would also be rather unwieldy, given the size of public high schools today. High school college counselors have their plates overflowing as it is, trying to manage merely their own workloads. However, it is typical to combine data over more than one year; most of that is for student privacy reasons.
