The studentId and/or districtStudentId is populated by a required field in our Manage Students UI. It is supplied by our partners and typically corresponds to a school district issued ID. We assume that it matches what is in their SIS, but we don’t have any way of enforcing that. studentId and districtStudentId are synonymous, but the field name varies depending on which NWEA service retrieves data from.
There is also a stateStudentId available in the API, which is the value a state uses to track students it’s SIS. This field is optional and won’t be used by all partners.
