- Key Symbols
Key symbols are simply one or two symbols that can be used with or without text to convey a single piece of information. At most, they provide the same amount of information as a short sentence of text. They can help reinforce meaning and give reassurance by acting as reminders for any level of reader.
Signage
Key symbols are
particularly effective when used in
signage. Wayfinding signage typically
communicates a single ‘sentence’, for
example ‘the swimming pool is this way’.
Even though this sentence may not
actually feature on the sign, key symbols
provide the ideal amount of information
to support the message on the sign,
increasing accessibility.
Documents
When using key symbols
within an inclusive document, each
key symbol will support one piece of
information, i.e. a concept within the
document’s text, such as the elements of
contact information.

When key symbols are used alongside a body of text or whole sentence, the symbols only indicate the subject. Symbol readers can best access these documents when assisted by a nonsymbol reader who can help them understand the message indicated by the key symbols.
Flashcards
Key symbols work really
well in sequencing and timetabling
activities. Key symbols can be particularly
effective when used on fl ashcards
displaying a series of events, with one
symbol representing each event within
the sequence. A child who might not be
able to read and understand a complex
timetable could use a series of flashcards
which each feature a key symbol as a
reference to know what they will be doing
during the day.

Symbol signage
Widgit have produced symbol signage at South Woodham Ferrers Leisure Centre to make wayfinding accessible to visitors with varying literacy levels.
Key symbols in a document
The use of key symbols is a very useful tool for communicating with people for whom English is not a primary language, or those who do not speak any English. The inclusion of symbols within documents, such as the Royal Berkshire NHS Foundation Trust’s A&E Communication Passport, can effectively aid the communication of a concept in a way that is simple and easy to understand, reducing reliance on text.
The A&E Communication Passport was developed to help hospital staff communicate with patients with learning impairments, and those for whom English is not a primary language.
By using key symbols for each question they need to ask, hospital staff are able to communicate the theme of a question to patients who would have had diffi culty in understanding the written text, and therefore gain an understanding of their situation and their needs.
