Accessible block-based coding for all
Google's Blockly supports block-based accessible programming for developers, students, and organizations
Expanding access for students with disabilities
Blockly is committed to developing inclusive tools that help all students succeed in learning computer science, including those with disabilities
Funding and support to advance accessibility
Blockly Accessibility Fund
We believe everyone should have the opportunity to learn computer science. This fund enables CS education-focused nonprofits to build and launch accessible features into their block based product and curricula. Together, we can make coding education a welcoming and engaging experience for everyone.
Accessibility partnerships
Working with the Google Blockly team and its partners has made me optimistic about the potential of making computer science truly accessible for all students.

Design for inclusivity
Below are helpful tips you can implement today when designing block-based product and instructional experiences:
Build for all senses
Account for multiple modalities for students to engage with your environment, including auditory, textual, and kinesthetic elements. For example, use audio cues to make spatial coding more inclusive.
Make learning gradual
Break down lessons into smaller steps using scaffolding tools like graphic organizers and checklists to support student comprehension and executive function. help students build confidence and understanding over time.
Use multiple formats
Create lessons that represent information in various ways, like magnetic blocks, 3D printed blocks, different block shapes and colors, text-to-speech, graphics, videos, and more.
