Integration
Arythmatic + LTI 1.3 (IMS Global)
Connect Arythmatic with any LTI-compatible tool or platform
Last Updated: April 2026
Arythmatic supports LTI 1.3 (Learning Tools Interoperability) for connecting with external learning tools, content providers, and institutional systems.
Why Connect LTI 1.3 (IMS Global) with Your LMS?
Educational institutions and training organizations using multiple learning tools need a standardized way to connect content, grades, and user data across platforms without building custom integrations for each vendor. Without LTI support, organizations are locked into a single vendor's content ecosystem, unable to incorporate best-of-breed tools, publisher content, or specialized simulation platforms into their training programs. Students and employees must log into multiple separate platforms to access different types of learning content, creating a fragmented experience. Grades and completion data from external tools must be manually transferred to the LMS gradebook, introducing errors and delays. The inability to launch external tools in context within courses means learners lose their place every time they switch between platforms. LTI 1.3 solves these interoperability challenges with secure, standards-based connections, but only when the LMS properly implements the specification.

How It Works
Expanded Setup Guide
Use Cases
Connect with publisher content via LTI
Integrate with institutional SIS systems
Launch external simulation tools within courses
Popular Automation Workflows
When a learner accesses an external tool in a course module, Arythmatic performs a secure LTI 1.3 launch, passing the learner's identity and course context to the tool.
When a learner completes an activity in an external LTI tool, the tool sends the grade back to Arythmatic via Assignment and Grade Services for gradebook recording.
Instructors use LTI Deep Linking to browse external tool content catalogs and select specific activities to embed in their Arythmatic course modules.
When another LMS or platform launches Arythmatic as an LTI Tool, Arythmatic delivers its courses within the external platform's interface with grade passback.
When an external LTI tool requests course roster information, Arythmatic responds with enrolled learner data via Names and Role Provisioning Services.
When an instructor adds publisher content, they register the LTI tool provider, configure the deployment, and map it to specific course modules for seamless access.

Frequently Asked Questions
Does Arythmatic support LTI?
Yes. Arythmatic supports LTI 1.3, the industry standard for learning tool interoperability, enabling connections with external tools, content providers, and institutional systems.
Does Arythmatic support LTI Advantage services?
Yes. Arythmatic supports LTI Advantage including Assignment and Grade Services (AGS) for grade passback, Names and Role Provisioning Services (NRPS), and Deep Linking.
Can Arythmatic act as both LTI Tool and Platform?
Yes. Arythmatic can act as an LTI Tool (launched from other platforms) and as an LTI Platform (launching external tools within its courses).
Is LTI 1.1 also supported?
Arythmatic supports LTI 1.3 as the primary standard. LTI 1.1 legacy support is available for older tools that have not yet upgraded to LTI 1.3.
