Final answer:
The separation authority for education requests exceeding 90 days is typically a high-ranking educational official or a court, depending on the situation and relevance of state laws and court precedents.
Step-by-step explanation:
The separation authority for all education requests that extend beyond 90 days traditionally falls under the purview of a higher education official or a judicial entity, depending on the context of the request. In cases where educational decisions are contested, such as in custody disputes or matters of educational policy, the district court or the applicable circuit court of appeals might be the deciding authority.
It's important to consider the specific educational laws of the state and any relevant court decisions that may impact these sorts of requests. As seen in historical cases, courts sometimes make determinations based on the constitutionality of educational segregation or other legal provisions related to the state's educational policies.
