LTI 1.3 (Learning Tools Interoperability) lets your LMS embed Exec roleplays as launchable activities inside a course. Learners click the activity in your LMS, sign in once via the LMS, and land directly in the assigned scenario — no separate Exec account or password required. When they finish, the score flows back into the LMS gradebook automatically. Exec implements the LTI 1.3 standard, so any LTI 1.3-compliant LMS should work. (LTI 1.1 is not supported.) Configuration is per workspace and admin-only — workspace admins set up the connection; everyone else just experiences single sign-on. *** ## What you get * **Single sign-on from your LMS** — Learners launching from the LMS are auto-provisioned in Exec and added to the workspace as a Member. * **Per-scenario launches** — Each LMS activity points at one Exec scenario, identified by its slug or ID. * **Grade passback** — When the roleplay is graded, the score posts back to the LMS as an [Assignment and Grade Services 2.0](https://www.imsglobal.org/spec/lti-ags/v2p0) score on the activity's lineitem. Best-of-N: the LMS only receives a score that improves on the previous submission. * **Self-service setup** — Admins connect an LMS from **Workspace settings → Integrations** without contacting Exec support. ## Prerequisites To connect an LMS to Exec you need: * **Workspace admin access in Exec.** The LTI settings page is admin-only. * **Admin access in your LMS** with permission to register external tools or LTI 1.3 platforms. * **Scenarios already created in your Exec workspace.** LMS activities reference scenarios by slug or ID, so the scenarios need to exist before you wire them up in the LMS. ## How it fits with other LMS integration options LTI 1.3 is the deepest of three LMS integration options. Pick based on what you need: | If you want to... | Use | | :--------------------------------------------------------------- | :------------------------------------------------------------------ | | Get started with the lightest possible setup | A simple link or button in your LMS pointing to your Exec workspace | | Keep learners inside the LMS UI | An iFrame embed | | Single sign-on + automatic score passback into the LMS gradebook | **LTI 1.3** | See [LMS Integrations](/lms-integration) for the comparison and the lighter-weight options. *** ## Next steps Walk through dynamic registration or a manual connection. Wire individual scenarios up as LMS activities. See how Exec scores flow back to your LMS gradebook. Diagnose launch failures using correlation IDs. *** ## Getting Help Need help with LTI setup?
