Accessibility = no barriersThe inclusive practice of removing barriers that prevent interaction with, or access to websites and services, by people with disabilities.
Accessibility = empowerment
Accessibility means that people with disabilities can use things independently
Accessibility is about people Accessibility means designing for the range of abilities your audience has
Accessibility means people can use the assistive technologies they rely on
Accessibility is achieved through• content• design• code
Accessibility means ensuring that people can successfully use a service - regardless of impairment or assistive technology
Accessibility has 4 characteristics• Perceivable• Operable• Understandable• Robust
GDS

Designing for disability benefits everyone
If people are excluded from digital services they will have to use older more expensive channels

Accessibility is requirement to pass a service assessment
Accessible content design
Can everyone perceive my content?
Ensure text has good legibility and readability • size• contrast• line height• line length
Ensure information is not communicated by colour alone
Ensure instructions do not rely on shape, colour or location
Provide appropriate text alternative for images
Provide transcript and captions for video with sound
Provide an audio description for information communicated visually in video
Can everyone operate my content?
Ensure link text helps a user know where they will be taken
Ensure headings are useful and hierarchical
Ensure page titles are unique and descriptive
Ensure all content and functionality is available to a keyboard
Can everyone understand my content?
Use plain English and keep content short, clear and simple
Avoid jargon, metaphors, colloquialisms and slang
Use contractions carefully
Expand the first use of an abbreviation
Ensure the language of your content provided
Use headings and lists to break content into manageable chunks
Ensure your content is in a logical order in the code
Provide clear form labels and hints
Provide helpful error messages
Ensure tables are simple and use the correct HTML
Provide a summary for complex information such as tables and charts
Consider using images and videos to support meaning
Avoid PDFs whenever possible
Is my content robust?
Is the code good?HTML - most appropriate elements CSS - no barriers Javascript - no barriers
Has your service been tested with a range of assistive technologies?
Who is everyone?
GDS
Example of people with visual impairments
I am colour blind and cannot perceive the difference between some colours
I have low vision and need to increase the text size in my browser
I have low vision and need to use a screen magnifier to make things bigger and cannot read text that has poor contrast
I am blind and use a screenreader
I am deafblind and use a braille device
Example of people with hearing impairments
I am hard of hearing and struggle to hear most things
I am Deaf; British Sign Language is my first language and I find English hard to read and write
GDS
Example of people with motor impairments
I have a mild motor impairment so struggle to use a mouse with fine control
I have a medium motor impairment so have to use a keyboard instead of a mouse
I have a severe motor impairment and am unable to use a mouse or keyboard so use speech recognition software
Example of people with cognitive impairments
I have dyslexia and struggle to process written text
I am on the autistic spectrum and have a literal understanding of text
I have attention deficit hyperactivity disorder (ADHD) and find it hard to concentrate
I have a learning difficulty and need thing to be simple and easy to understand
I have a poor memory and I get easily confused
How do you know if it’s accessible?
Getting an accessibility specialist to evaluate your service against WCAG 2.0 is an effective way to identify accessibility barriers
The WebAim Checklist is a great introduction to WCAG 2.0
http://webaim.org/standards/wcag/checklist
Include a range of people with disabilities in your user research, throughout the project
Lessons from the Passport Renewal Service
The earlier you start considering accessibility the easier it is
Join the Accessibility Community
The accessibility community is a place to observe discussions, ask questions, share experiences and establish best practice
The newly re-launched accessibility blog is also great way to find out more about accessibility
