User Guide for 1EdTech’s LTI Diagnostics & Certification

Abstract

This LTI Diagnostic and Certification Guide defines the processes, tools, and resources used to evaluate, troubleshoot, and validate an implementation of LTI v1.3 and LTI Advantage. Its purpose is to help organizations understand how to verify conformance, diagnose common issues, and complete the certification workflow. By outlining the required steps, expected behaviors, and diagnostic methods, the guide supports consistent, accurate, and reliable certification of LTI integrations across Platforms and tools.

Introduction

LTI® Diagnostics & Certification can be used to validate and certify your implementation of LTI. It is a part of build.1edtech.org, 1EdTech’s developer resource portal.

The currently supported diagnostic and certification functionality for LTI Tools and Platforms are:

• LTI Core
• Deep Linking
• Names & Roles Provisioning Service
• Assignments & Grades Service

Over time, additional specifications will be added to the LTI Diagnostics & Certification testing suite.

Selecting LTI Version and Role

Select LTI v1.3 and either Tool or Platform, based on what you are interested in validating.


Upon starting the testing, you will see the following main menu options. These options are the same for both Tools and Platforms:

• Diagnostics – observations and details of the tests executed will be displayed here
• Settings – configuration details for the product should be entered here
• Certification – certification submissions are made here
• Support – access to support options can be found here

Testing a Tool

Settings

To test your Tool, start by registering your Tool in the LTI Diagnostics & Certification testing suite via the Settings menu. The testing suite will act as a platform from which to launch your Tool.

Dynamic Registration

If your Tool supports Dynamic Registration, you can enter your Tool’s Dynamic Registration URL and click on Register to complete the registration process.


Your Tool’s configuration will automatically be populated in the settings.


Manual Registration

Toggle off Dynamic Registration to expose the LTI Diagnostics & Certification platform configuration details and manually enter your Tool’s configuration.

Diagnostics

Tool Diagnostics are made up of three tabs:

• Links
• Launch iFrame
• Diagnostics Data


Links

Once registered, a basic LTI launch link for your Tool will be created. You can add additional links manually or via Deep Linking using the Add menu. Once added, they will appear in the Links list, from which they can be launched. You can choose the user Role for the launch, as well as whether to launch in an iFrame or a Window.


Launch iFrame

If you select iFrame for the launch, your Tool will appear in the Launch iFrame tab.


Diagnostics Data

On the Diagnostics Data tab, you will see the observations and details that the LTI Diagnostics & Certification testing suite is recording and validating as your Tool interacts with it.

• A green check mark indicates that the action was successful.
• A red X identifies an action that was not successful.

Each test includes a drop-down with additional details on the test results.


---

Testing a Platform

Settings

To test your Platform, start by registering the LTI Diagnostics & Certification testing suite. The testing suite acts as a Tool that your Platform can launch. The details of the testing suite are available via the Settings menu.

Dynamic Registration

If your Platform supports Dynamic Registration, you can enter the testing suite’s Dynamic Registration URL into your Platform.


When the registration in your Platform is complete, you can refresh the testing suite’s Settings page to see the configuration details.


Manual Registration

Toggle off Dynamic Registration to expose the LTI Diagnostics & Certification Tool configuration details and manually enter your Platform’s configuration.


---

Diagnostics (Platform)

On the Diagnostics page, you will see the observations and details that the LTI Diagnostics & Certification testing suite is recording and validating as your Platform interacts with it. The process is started by launching the testing suite Tool within your Platform.

• A green check mark indicates that the action was successful.
• A red X identifies an action that was not successful.

Each test includes a drop-down with additional details on the test results.

Certification

Once you have completed diagnostic test sessions that meet LTI specification requirements (green diagnostics indicators), you can submit those sessions for certification.

Start by clicking on the Certification navigation link. You will then proceed with selecting the certification you are requesting for your product in the drop-down menu. Once selected, choose the supporting diagnostic test session(s) until all certification criteria are met. Once all criteria have been met, select Review.

 

After reviewing the submission details and certifying that the diagnostic data gathered was for the selected product, you can apply for certification.


After you click on Apply, there will be a slight delay until you receive a submitted response from the system.


A certification case will be sent to our support team, and you will receive an automated response confirming receipt. The support team will manually validate your application and contact you regarding the granting of your certification.
