Yes. Tribal consultation is based on building relationships to help support Indigenous students. Student enrollments fluctuate over the years. When you consider the Title grants covered under ESSA consultation and the specific needs these grants address, they go beyond tribal membership. Tribes may have resources or best practices to assist the LEA in supporting all Indigenous students (i.e. migratory, at risk, English learner, etc.).
If an LEA does not have any students enrolled from a tribe, it is most likely the tribe will choose to opt out of tribal consultation, but the tribe needs to be given the option to do so. In that case, the authorized tribal representative would check the "Tribal opt out" box on the Affirmation of Tribal Consultation form and sign.
However, an LEA may find that these tribes have valuable resources that could support the LEA's Title grant programs. Particularly if you review the list of other LEAs these tribes are consulting with (Affected LEAs section, Tribes and Affected LEAs link). There could be best practices the tribe uses with other LEAs that may be applicable to your organization. The intent of consultation is to open dialogue and identify all options for supporting our students.
