Assistive Technologies
Students with disabilities and impairments rely on these assistive technologies. To see how we can understand their user experience and better help students with disabilities, it is important to be familiar with these tools.

Coding Guidelines
When writing code, it is important to follow accessibility standards to ensure that applications can be used by everyone, including individuals with impairments and disabilities.
- Accessible Rich Internet Applications (ARIA) is a W3C specification that provides a way to make dynamic web applications and advanced user interface controls more accessible to people with disabilities.
- WAI-ARIA Authoring Practices is an essential resource for anyone developing websites or web applications. It provides standard design patterns for dozens of common web widgets such as accordions, dialogs, and menus.
- Accessibility for Apple Developers is Apple’s site for iOS developers to make applications accessible to users.
- Accessibility for Android Developers is Google’s site for Android developers to make applications more accessible.
Code Validators
To ensure that your code meets accessibility standards, use the following code validators.
- HTML Validator – Developed by W3C.
- CSS Validator – Developed by W3C.
- HTML Tidy: This is a software library that evaluates and cleans up HTML, automatically generating a reformatted (i.e., “tidied”) version. HTML Tidy is widely available, and is integrated into many web coding applications as documented on their website.
