Haw. Code R. § 8-63-42
The assistant superintendent shall create positions exempted from civil service as permitted by section 76-16, Hawaii Revised Statutes, or as may otherwise be permitted by law. The assistant superintendent may also exempt a position temporarily when a position is pending establishment of a new class, or may exempt a position permanently when the establishment of a class is impracticable. Exempt appointments also include positions that have a narrow limitation period that precludes completion of probation. The assistant superintendent shall review on a periodic basis the exempt positions to determine whether such positions should continue to be exempt and may revoke a previously authorized exemption when the particular position or services no longer meets the criteria or conditions for exemption.
