Open and Distance Learning (ODL) is an educational approach that combines open enrollment, flexible access, and distance delivery to facilitate learning outside traditional on-campus settings. ODL uses a mix of synchronous and asynchronous activities, often employing online platforms, printed learning materials, broadcast media, and other communication channels. It serves a broad range of learners, including working adults, rural residents, and those with geographic, financial, or time constraints.

Delivery and components: Courses are typically designed for self-study with tutor support, periodically assessed through assignments and exams. Delivery may be online via learning management systems, video lectures, and digital resources, or hybrid with print materials and television or radio broadcasts. Assessment may include quizzes, essays, projects, and proctored examinations. Quality assurance and accreditation bodies oversee program standards.

History and scope: ODL emerged from correspondence education in the late 19th and 20th centuries and expanded with universities dedicated to distance education. The Open University in the United Kingdom, established in 1969, remains a landmark example, followed by large open universities in many countries (e.g., IGNOU in India). International organizations support best practices and policy frameworks for ODL, promoting access and lifelong learning.

Benefits and challenges: ODL expands access, supports lifelong learning, and can reduce costs and travel requirements. However, it faces challenges such as the digital divide, ensuring consistent quality and recognition across jurisdictions, student retention, and the need for robust instructional design, advisor services, and reliable assessment methods.
