The only way that dyslexia can be formally identified is by a Diagnostic Assessment carried out by a qualified assessor.
Screening tests can be a handy tool as long as they are carried out with the understanding that they only indicate possible dyslexic difficulties. They are not a diagnosis.
There are many different screening tests. Some are delivered by computer; others need to be administered by a teacher/SENCo. Some give an estimate as to whether the child/person is likely to have dyslexic difficulties. A few offer a more detailed profile of strengths and weaknesses, which help inform an appropriate teaching strategy.
Where any screening test indicates a moderate or high probability of dyslexic difficulties, the best course of action is to follow up with a full diagnostic assessment. This would determine the precise nature of dyslexia and related difficulties.
Lucid Rapid Dyslexia Screening is a 15 minute, quick screening for dyslexia in the 4 to 15 age range.
Based on research from Hull university, Rapid is a solution for quick group/class screening for dyslexia in pupils aged 4 to 15.
It comprises of three enjoyable and non-threatening tests that are sensitive cognitive indicators of dyslexia and cover phonological skills, working memory and phonic decoding.
Phonological processing (4 - 15 years)
Working memory (4 - 15 Years)
Depending on age, the third subtest is either:
Visual-verbal integration memory (4 - 7 years)
or
Phonic decoding skills (8 - 15 years)
