"og:title": "AICC — HACP, CMI001, and the tools that still support it" --- # **AICC — HACP, CMI001, and the tools that still support it** The pre-SCORM interoperability rules, still worth knowing because HACP crosses domains where SCORM cannot. Written and maintained by the scorm-tools.com editor. 7 listed tools state support. ## **What AICC is ** The Aviation Industry Computer-Based Training Committee wrote the interoperability rules that SCORM later absorbed. Formed in 1988 to stop aircraft manufacturers shipping mutually incompatible training systems, it published a series of guidelines and recommendations; the ones that still come up are AGR-006, for file-based course-to-management-system communication, and AGR-010, for web-delivered courses. What people usually mean by "AICC support" is HACP, the HTTP AICC Communication Protocol. The course posts form-encoded messages to a URL the management system supplied and receives plain-text, INI-style responses. Because that is a server-to-server exchange rather than JavaScript reaching into a parent window, HACP content can be hosted on a different domain from the LMS without the cross-origin problems SCORM runs into — which is why some hosting and dispatch products still offer it. AICC’s data model is the direct ancestor of SCORM’s: CMI001 defined the lesson status, score and core elements SCORM 1.2 went on to reuse. The committee dissolved in 2014, handing its unfinished successor work — what became cmi5 — to ADL. Nothing new is being written for AICC, there is no active certification, and support is slowly being dropped. Treat it as a compatibility target for content that already exists, not as a choice for new work. ## **Versions and what changed ** Release history of AICC | **Version ** | **Released ** | **What changed ** | | --- | --- | --- | | **AICC formed** | 1988 | Founded by aviation training buyers and suppliers to define common CBT interoperability rules. | | **AGR-006** | c. 1993 | File-based CMI interoperability: the course and the management system exchange data through files. | | **AGR-010** | c. 1998 | Web-based CMI, introducing HACP — the HTTP protocol most "AICC-compatible" products implement. | | **CMI001 v4.0** | 2004 | The consolidated interoperability guidelines, and the data model SCORM 1.2 built on. | | **Committee dissolved** | 2014 | AICC closed. Its successor work moved to ADL and became cmi5. No body now certifies AICC conformance. | ## **Who says so ** We link to the specification and to other people's registries. We do not run a conformance programme and we do not issue badges of our own: a claim here is registry-verified only when an official registry says so, and otherwise it is marked as the vendor's statement or as our own check on a date. ### **Specification ** - [~~AICC specification archive (GitHub)~~](https://github.com/AICC) ### **Registry ** - [~~No active registry~~](https://github.com/adlnet) AICC dissolved in 2014 and no organisation certifies AICC conformance today. Every AICC claim on this site is therefore vendor-stated or editor-checked; none can be registry-verified. ## **Tools that support AICC** Grouped by what the tool does, and within each group ordered by how well the claim is evidenced: registry entries first, then facts we checked ourselves, then the vendor's own statement. ### [~~Players, runtimes & debuggers~~](https://scorm-tools.com/categories/players-runtimes-debuggers) Players, runtimes & debuggers that support AICC | **Tool ** | **Evidence ** | **Licence ** | **Pricing ** | | --- | --- | --- | --- | | [~~Moodle SCORM activity (mod\_scorm)~~](https://scorm-tools.com/tools/moodle-mod-scorm)The SCORM player inside Moodle — the most exercised open-source runtime there is | [editor-checked— source, opens in a new tab](https://github.com/moodle/moodle/blob/main/public/mod/scorm/settings.php) Checked 24 August 2026 | GPL-3.0-or-later | Open source | ### [~~Testing, validation & conformance~~](https://scorm-tools.com/categories/testing-validation-conformance) Testing, validation & conformance that support AICC | **Tool ** | **Evidence ** | **Licence ** | **Pricing ** | | --- | --- | --- | --- | | [~~Prism~~](https://scorm-tools.com/tools/prism-wcag-audit)Unzips a SCORM, AICC, cmi5 or xAPI package and runs axe-core over every page in it | [editor-checked— source, opens in a new tab](https://github.com/davenguyen87/Prism/blob/main/src/parser/aicc.js) Checked 24 August 2026 | MIT | Open source | ### [~~Packagers, SDKs & libraries~~](https://scorm-tools.com/categories/packagers-sdks-libraries) Packagers, SDKs & libraries that support AICC | **Tool ** | **Evidence ** | **Licence ** | **Pricing ** | | --- | --- | --- | --- | | [~~SCORM Cloud API v2 clients~~](https://scorm-tools.com/tools/scorm-cloud-api-clients)Rustici's generated client libraries for the SCORM Cloud REST API, in six languages | [editor-checked— source, opens in a new tab](https://github.com/RusticiSoftware/scormcloud-api-v2-client-java/blob/master/src/main/java/com/rusticisoftware/cloud/v2/client/model/CourseSchema.java) Checked 24 August 2026 | Apache-2.0 | Open source | | [~~eLearning Module Parser~~](https://scorm-tools.com/tools/elearning-module-parser)Java library that detects and parses SCORM, AICC, cmi5 and xAPI packages into typed metadata | [vendor-stated— source, opens in a new tab](https://github.com/jcputney/elearning-module-parser#supported-formats) Checked 24 August 2026 | Apache-2.0 | Open source | ### [~~LMS & LMS plugins~~](https://scorm-tools.com/categories/lms-and-plugins) LMS & LMS plugins that support AICC | **Tool ** | **Evidence ** | **Licence ** | **Pricing ** | | --- | --- | --- | --- | | [~~Chamilo LMS~~](https://scorm-tools.com/tools/chamilo)Full open-source LMS with SCORM 1.2 and AICC learning paths and a bundled LTI plugin | [editor-checked— source, opens in a new tab](https://github.com/chamilo/chamilo-lms/blob/master/public/main/lp/aicc.class.php) Checked 24 August 2026 | GPL-3.0 | Open source | | [~~Moodle~~](https://scorm-tools.com/tools/moodle)The most widely deployed open-source LMS, and the SCORM behaviour most content gets tested against | [editor-checked— source, opens in a new tab](https://github.com/moodle/moodle/blob/main/public/mod/scorm/datamodels/aicclib.php) Checked 24 August 2026 | GPL-3.0-or-later | Open source | | [~~Totara Learn~~](https://scorm-tools.com/tools/totara-learn)Moodle-derived enterprise LMS, GPL-licensed but distributed only through a paid subscription | [vendor-stated— source, opens in a new tab](https://totara.help/docs/add-a-scorm-activity) Checked 24 August 2026 | GPL-3.0 | On application | ## **Choosing between them ** ### **AICC or SCORM?** SCORM, unless you are maintaining existing AICC content or you specifically need HACP’s cross-domain behaviour. AICC has no active steward, no certification and shrinking support. ### **Why would anyone still choose HACP?** Because it works across origins. A course served from a vendor’s domain can report to an LMS on another domain without the window-hierarchy access SCORM depends on. Modern dispatch products solve the same problem differently, and are listed under distribution. ## **Questions people ask about AICC** ### **What is HACP?** The HTTP AICC Communication Protocol: the course sends form-encoded POSTs to a URL supplied at launch and parses plain-text responses. It is the web-era part of AICC and the part still implemented. ### **Is AICC still supported by LMSs?** By many of the older and larger ones, yes, and by fewer new ones every year. The listings below record what each product states, and when we last checked it. ### **What is the difference between AICC and SCORM 1.2?** They share a data model lineage. The difference is transport: AICC/HACP talks over HTTP between servers, SCORM 1.2 talks through a JavaScript object in the browser. That single difference decides which one can cross domains. ### **Can I convert AICC content to SCORM?** Usually, because the data models are close relatives. Converters are listed under converters and migration; the awkward part is normally the launch and the manifest, not the tracking data. ### **Who maintains AICC now?** Nobody. The committee dissolved in 2014. Its successor project moved to ADL and became cmi5, which is where new work went. ## **The other standards ** **SCORM 1.2** The oldest version of SCORM still in daily use, and still the safest export format when you do not control the target LMS. [SCORM 1.2](https://scorm-tools.com/standards/scorm-1-2) **SCORM 2004** The second generation of SCORM: a larger data model, and sequencing rules the LMS is required to enforce. [SCORM 2004](https://scorm-tools.com/standards/scorm-2004) **xAPI** A way to record that somebody did something, anywhere, and keep it in a store you control. [xAPI](https://scorm-tools.com/standards/xapi) **cmi5** The xAPI profile that supplies what xAPI deliberately left out: how an LMS launches a course and how the two agree it is finished. [cmi5](https://scorm-tools.com/standards/cmi5) **LTI** A launch protocol, not a packaging format: the LMS sends the learner to a tool that stays where it is.
