GSIS

GSIs is an acronym that may refer to more than one concept. The most common in academic settings is Graduate Student Instructors, who are graduate students engaged in teaching undergraduate courses. In the United States and elsewhere, GSIs typically conduct discussion sections or laboratory sessions, assist with grading, hold office hours, and provide student support. They usually work under a faculty supervisor and receive a stipend or tuition remission as part of their graduate program appointment. Responsibilities and appointment terms vary by institution, but pedagogy training and professional development are often provided.

In the information technology and business services sector, GSIs stands for Global System Integrators. These are large, multinational firms that design, implement, integrate, and manage complex technology solutions for enterprises. Their work spans requirements analysis, architecture, software and hardware integration, data migration, system integration, and ongoing managed services. GSIs typically collaborate with vendor ecosystems, deliver cross-functional programs, and operate across multiple geographies, industries, and regulatory regimes. They differ from traditional system integrators by scale, standardized methodologies, and global delivery capabilities.

Other usages include contexts where the acronym is applied to national or regional organizations whose names yield GSI or GSIs in plural, though such examples vary by country and are less standardized. To determine the intended meaning, one should rely on context, such as whether the reference is about education, IT services, or a specific organization.
