Why e-learning standards matter
If you commission e-learning content from an external vendor and build or procure a learning management system separately, the standard the content uses determines whether the LMS can track learner progress, record completions, and pass scores to compliance reports.
Get the standard wrong, and your carefully crafted course content sits in your LMS as a static file with no tracking. Get it right, and every learner interaction is recorded, every completion is logged, and every assessment score flows into your reporting.
SCORM: the workhorse standard
SCORM (Sharable Content Object Reference Model) has been the dominant e-learning standard since 2001. SCORM 1.2 and SCORM 2004 are the two versions you will encounter in practice.
SCORM packages are ZIP files containing the course content plus a manifest file. When a SCORM package is launched inside a SCORM-compliant LMS, the content and the LMS communicate via a JavaScript API — passing completion status, score, and time-on-task back to the LMS.
What SCORM tracks well
- Course completion (pass/fail/incomplete)
- Assessment scores
- Time spent in the course
- Bookmarking (where the learner left off)
SCORM's limitations
- Requires a browser (no offline learning)
- Data stays inside the LMS — no cross-system reporting
- Limited to what was imagined in 2001 — no support for social learning, informal learning, or mobile contexts
- SCORM 2004's sequencing rules are notoriously complex and inconsistently implemented across LMS platforms
xAPI: the modern alternative
xAPI (Experience API, also called Tin Can) was designed to overcome SCORM's limitations. Rather than communicating via a JavaScript window object, xAPI sends statements to a Learning Record Store (LRS) via a REST API.
xAPI statements follow a simple subject-verb-object structure: "Sarah completed Module 3", "James scored 87% on the assessment", "Maria watched the video for 8 minutes".
What xAPI enables
- Learning from anywhere — mobile apps, simulations, physical sensors, real-world activities
- Cross-system learning records — an LRS can aggregate learning from multiple platforms
- Richer tracking — not just completion, but every interaction, simulation step, and knowledge demonstration
- Offline support via queue-and-sync patterns
xAPI's adoption reality
The promise of xAPI has not fully materialised in most enterprise deployments. Authoring tools produce xAPI content, but most LMS platforms treat it similarly to SCORM (launch, complete, score) because most clients do not have a separate LRS or a use case for cross-system learning records.
Which should you choose
For most corporate e-learning use cases in 2025, SCORM 1.2 is still the pragmatic choice. It is universally supported, straightforward to implement, and sufficient for tracking completion and assessment scores for compliance purposes.
Choose xAPI if you are building a custom LMS and need richer tracking beyond completion/score, connecting learning data across multiple platforms or tools, or supporting learning scenarios beyond browser-based e-learning (mobile apps, simulations, on-the-job activities).
If in doubt, commission or build content that supports both. Most modern authoring tools (Articulate Storyline, Adobe Captivate) can publish to SCORM 1.2, SCORM 2004, and xAPI simultaneously.
