As an assistant superintendent, your job duties depend on the industry in which you work and the needs of the superintendent. You may work in a school district where you handle administrative responsibilities, develop district policy and curriculum, oversee issues related to students, and support the efforts of the district superintendent. If you work as a construction superintendent, you provide job site management of both employees and contractors. In a manufacturing assistant superintendent role, you help manage manufacturing operations by overseeing employees and performing inspections to ensure that each product or project meets required specifications.
