This guide covers platform access, browser setup, allowlist needs, email sharing, and integration setup. ### **Who this is for** This article is for: 1. District technology teams. 2. School administrators. 3. Implementation leads. 4. Teachers helping confirm student access. ### **Platform access** The main 220 platform is: learn.220leadership.com 220 programming may also use Content2Classroom platform services, video streaming, embedded digital tools, and external document or project-sharing workflows. ### **Recommended browser setup** For best performance, use a current version of Chrome or Safari on a supported school device. JavaScript should be enabled. Students and teachers should use the login process provided by their school or 220 contact. ### **Domains to allow** District technology teams should allow access to these domains: - \*.content2classroom.com - publisher.content2classroom.com - wiris.content2classroom.com - stream.content2classroom.com - learn.220leadership.com - ed.link *(Required for Single Sign-On and rostering integrations)* - \*.canva.com - \*.calendly.com These domains support platform access, course content, video loading, embedded tools and related learning workflows. ### **Email and sharing allowlist** District technology teams should allow communication from: @220leadership.com For Work-Based Learning programs, schools may also need to allow sharing with: [wbl@220leadership.com](mailto:wbl@220leadership.com) This address may be used for student project submission, review, or related Work-Based Learning workflows when applicable. ### **Notes for Work-Based Learning** **1. Canva** Some Work-Based Learning projects may involve Canva or similar design tools. If students need to share Canva files with 220, district Canva settings may need to allow students to share designs outside the school’s Canva team with the approved 220 submission contact or email domain. If file upload is used in place of external sharing, this setting may not be needed. If sharing is restricted, students may need help from a teacher, school Canva admin, or district technology team. **2. Google Meet (for Live Sessions)** If your Work-Based Learning students will be joining live sessions via Google Meet, standard web whitelisting is not enough. By default, Google Workspace prevents student Organizational Units (OUs) from joining meetings hosted by external domains. To allow access, your Google Workspace Administrator must: 1. Go to the **Google Admin Console**. 2. Navigate to **Apps** \> **Google Workspace** \> **Google Meet**. 3. Click on **Meet safety settings**. 4. Select the specific Student OUs that use our program. 5. Under *Joining meetings*, ensure the setting allows users to join meetings created by external organizations. **3. Calendly** Students use Calendly to schedule meetings and sessions with mentors. Please ensure this domain is accessible for student devices. ### **Video loading** If videos do not load, check that the required platform and streaming domains are allowed through the school’s firewall and web filters. Also confirm that students are using a current browser and the correct login process. ### **Integration setup** When rostering, SSO, LMS, or SIS integration is required, 220 uses Edlink to support those integrations. Integration details should be coordinated during implementation. Your school or 220 contact will confirm the expected setup process. ### **Manual setup** Some schools use manual setup through the platform. Manual setup may include: 1. Creating teacher accounts. 2. Creating classes. 3. Adding the correct 220 course. 4. Sharing student access codes. 5. Confirming that students can access the correct class and course. Use manual setup only when your school or 220 contact has directed you to use manual setup. ### **District IT checklist** Before launch, confirm that: 1. Teachers and students can access learn.220leadership.com. 2. Required Content2Classroom and Edlink (\*.ed.link) domains are allowed. 3. Video content can load. 4. JavaScript is enabled. 5. Teachers and students are using current browsers. 6. 220 email communication is allowed. 7. If using Work-Based Learning: Canva and Calendly are accessible to students. 8. If using Work-Based Learning: Google Meet safety settings are configured to allow student OUs to join external meetings. 9. Edlink integration setup has been coordinated if your school uses integration setup. 10. Manual setup instructions have been shared if your school uses manual setup. **Need more help?** Use Support or contact your school/district implementation contact. - [Back-to-School Updates 2026-27](https://support.220leadership.com/help-center/back-to-school-updates-2026-27) - [Getting Access](https://support.220leadership.com/help-center/getting-access) - [Assignments and Gradebook](https://support.220leadership.com/help-center/assignments-and-gradebook) - [Work-Based Learning](https://support.220leadership.com/help-center/work-based-learning) - [Setting Up Your Class](https://support.220leadership.com/help-center/setting-up-your-class) - [Platform Help](https://support.220leadership.com/help-center/platform-help) - [Managing Your Classes and View](https://support.220leadership.com/help-center/managing-your-classes-and-view) - [Languages and Accessibility](https://support.220leadership.com/help-center/languages-and-accessibility) - [Troubleshooting](https://support.220leadership.com/help-center/troubleshooting) - [About 220](https://support.220leadership.com/help-center/about-220) - [Choosing and Funding a Program](https://support.220leadership.com/help-center/choosing-and-funding-a-program) - [Reports](https://support.220leadership.com/help-center/reports) [![Frame 84 (3)](https://support.220leadership.com/hs-fs/hubfs/Frame%2084%20(3).png?width=100&height=100&name=Frame%2084%20(3).png "Frame 84 (3)")](http://220leadership.com) Copyright © 2026, 220 Youth Leadership
