LMS, cohort, MOOC, proctored exam—a reference guide to the terminology you'll encounter across online education platforms and programs.
Why the Vocabulary Matters
Signing up for an online course often means landing on a platform that assumes you already know the lingo. Terms like LMS, proctored exam, and cohort appear in enrollment pages and syllabi without much explanation. Misunderstanding them can lead to surprises — a "self-paced" course with a hard deadline, or a certificate that turns out not to carry academic credit.
This reference guide defines the terms you're most likely to encounter before and during an online learning experience. Bookmark it and return whenever something in a course description leaves you puzzled. For a broader orientation, see our comprehensive online education resource.
LMS (Learning Management System)
The digital platform that hosts a course's videos, readings, assignments, and communication tools. Think of it as the online classroom itself.
MOOC
Massive Open Online Course — a large-scale online course open to anyone, typically offered by universities or platforms at low or no cost, sometimes with a paid certificate option.
Proctored Exam
A supervised assessment designed to verify your identity and monitor for academic dishonesty, conducted via webcam software or at an approved testing center.
Cohort
A defined group of learners who begin and progress through a course together on the same timeline, often engaging in shared projects and discussions.
Accreditation
Formal recognition by an independent body that an institution or program meets established educational standards, which affects credit transferability and financial aid eligibility.
CEU (Continuing Education Unit)
A standardized unit used to track professional development hours — ten contact hours of instruction equals one CEU — distinct from academic credit.
Asynchronous Learning
A course delivery mode where students access materials and complete work on their own schedule rather than at a fixed time set by the instructor.
Academic Credit
A formal unit of measurement representing completed coursework that can count toward a degree or be transferred to another accredited institution.
Platform and Delivery Terms
Understanding how a course is delivered shapes everything from your daily schedule to what technology you'll need.
| Most common LMS platforms | Canvas, Blackboard, Moodle, proprietary systems |
| Typical CEU definition | 1 CEU = 10 contact hours of instruction (International Association for Continuing Education and Training) |
| Self-paced vs. cohort | Self-paced: flexible schedule; Cohort: fixed start/end dates |
| Certificate vs. credit | Certificates confirm completion; academic credit counts toward a degree |
| Accreditation relevance | Required for federal financial aid and credit transfer eligibility (U.S. Department of Education) |
- Learning Management System (LMS)
- The software platform where a course lives — where you watch videos, submit assignments, and communicate with instructors. Common examples include Canvas, Blackboard, and Moodle, though many providers build proprietary systems.
- MOOC (Massive Open Online Course)
- A course designed to accommodate thousands of learners simultaneously, typically offered through large platforms. MOOCs range from free audit options to paid certificate tracks.
- Synchronous vs. Asynchronous
- Synchronous learning happens at a scheduled time (live video sessions, real-time discussions). Asynchronous learning lets you engage with material on your own schedule. Many courses blend both. Learn how each format affects your experience.
- Self-Paced Course
- A course with no fixed session schedule — you progress through content at your own speed. Note that "self-paced" does not always mean no deadline; check the enrollment terms carefully.
Assessment and Credentialing Terms
How your work is evaluated — and what you receive at the end — varies widely across online programs. These definitions help you set accurate expectations.
- Proctored Exam
- An exam monitored to verify your identity and deter cheating. Online proctoring typically uses webcam software that records your session; some programs require an in-person testing center.
- Certificate of Completion vs. Academic Credit
- A certificate of completion confirms you finished a course; it carries no transferable academic credit. Academic credit — measured in credits or credit hours — counts toward a degree. Not all certificates lead to credit, so verify this before enrolling. Our pre-enrollment checklist covers this and other critical questions.
- Accreditation
- A quality-assurance process in which an independent body evaluates whether an institution or program meets defined standards. Attending an accredited program matters most when transferring credits or applying for federal financial aid.
- CEU (Continuing Education Unit)
- A standardized measure (typically 10 contact hours per CEU) used by professional licensing bodies to track professional development. CEUs are distinct from academic credit hours.
Community and Participation Terms
Online courses vary enormously in how much interaction they expect from learners. Knowing these terms helps you gauge your time commitment and social obligations before you enroll.
- Cohort
- A group of learners who move through a course together on the same schedule, often collaborating on projects and discussions. Cohort-based courses tend to have fixed start dates and stronger community bonds.
- Discussion Forum / Discussion Board
- An asynchronous space within an LMS where students post responses to prompts and reply to peers. Participation is often graded and counted toward the course total.
- Office Hours (Virtual)
- Scheduled times when an instructor or teaching assistant is available for live questions, usually via video call. Availability varies by program; some courses offer none.
