ISD is an acronym used for several organizations and concepts across education, governance, policy, and technology. This article provides a concise overview of the most common usages.

Instructional Systems Design (ISD) or instructional design is a systematic process for designing, developing, and evaluating educational and training programs. ISD typically follows models such as ADDIE (Analyze, Design, Develop, Implement, Evaluate) and is applied in schools, corporate training, and e-learning to align learning objectives with assessments and activities.

Independent School District (ISD) is a designation for certain public school districts in the United States, especially in Texas. Independent districts are legally separate from city or county governments and have autonomy over budgeting, staffing, and curricular decisions within state law.

Institute for Strategic Dialogue (ISD) is a London-based think tank focusing on international politics, extremism, and policy research. Other organizations also use ISD as an acronym, including institutes dedicated to sustainable development or science and design in various countries.

In procurement and project contexts, ISD can stand for in-service date or initial service date, indicating when a system, equipment, or software is first deployed and becomes operational.

Because ISD has multiple meanings, context is needed to determine the intended reference.
