Screen for dyslexia in as little as 20-minutes


About the Program

Nessy believes that all students should be screened for dyslexia by the age of 7 to identify and support all struggling readers in the classroom.

Our Dyslexia Quest screening tool provides a report of learning abilities associated with dyslexia. Administered in as little as 20 minutes, its game-based format motivates students to perform at their best, without even realising they are being assessed.


Assessment Breakdown

Assessment game 1: Visual Word Memory

Using commonly misspelled words, hold a visual memory of a word and find the correct match.

Assessment game 2: Auditory Sequential Memory

Listen to a series of instructions and follow them in the correct sequence.

Assessment game 3: Visual Sequential Memory

See a sequence of graphic symbols and find the correct match.

Assessment game 4: Processing Speed

Match a sequence of symbols to numbers.

Assessment game 5: Phonological Awareness

Manipulate and sequence phonemes.

Assessment game 6: Working Memory

Listen, then recall a sequence of numbers in reverse order


How It Works

Students climb the six levels of “Yeti Mountain”, each offering a different test of cognitive ability from memory to processing speed to phonemic awareness. The resulting student profile allows teachers and administrators to identify students at risk of dyslexia.

There are 3 pathways up Yeti Mountain for the child to work their way up, playing games that test 6 areas of learning and memory. Only one pathway should be played at a time with at least a 2 month break between each turn – we recommend once termly. This allows parents and teachers to compare results and monitor progress and response to intervention.

History & Research

Nessy Headquarters is located in the same building as the Bristol Dyslexia Centre and specialist school and was founded by a teacher from the centre. As a result of our insider knowledge and research, the Dyslexia Quest Screening App released in 2011 was based on the tests of educational psychologists, mirroring the output that they would assess to determine the likelihood of dyslexia.

The efficacy of our app has been researched thoroughly by Barry Carbol, Ph.D. and the research paper can be found here. Since the release of the app we have been working to develop it into a more comprehensive dyslexia test that provides a snapshot of learning abilities linked to dyslexia and because it’s games based, students have fun without realising they are being assessed.

To understand the reports and the help children with dyslexia require further, we recommend partnering your screening tool with both Dyslexia Training and intervention therapy in the form of Nessy Reading & Spelling.
