In Brief – January 2022
Last year we conducted another statistical survey which confirmed earlier findings regarding the strong association between the QuickScreen dyslexia test and an independent dyslexia assessment. The result provided us with a high accuracy rate of 93%. The data used was the entire test intake during one calendar month and it comprised a mix of students at university, professionals at work and other members of the public covering quite a wide age span.
In the coming year we are planning to carry out an updated evaluation of the link between our QuickScan questionnaire, the QuickScreen dyslexia test and independent assessment reports, in order to explore the predictive ability of the initial questionnaire to accurately indicate the presence of learning differences.
The QuickScreen dyslexia test is designed to act as a ‘functional dyslexia screener’ that provides immediate and detailed insights into an individual’s current learning profile. It is not a diagnosis. The report provides a basis upon which individual support programmes can be devised, reasonable adjustments put in place at work and where possible additional time in written examinations be considered.
Degrees of compensation are also taken into consideration and may positively influence a dyslexia conclusion, by reducing it to a Mild or Borderline category, where overall attainment levels are found to be well established.
To ensure our test is verified and proven, we regularly undergo independent research. You can read our latest full report using the link below or scroll down for headline results.

Headline Results from 2021 Research
An essential step in the evaluation process of any diagnostic/screening test is to assess its accuracy. The overall accuracy of a diagnostic test indicates how good it is at correctly identifying people with and without the condition in question. It is the probability that someone’s status is correctly identified by the test.
The latest statistical study provides an independent analysis of the diagnostic accuracy of QuickScreen based on the test’s dyslexia quotient (degree of consistency with a dyslexia profile, based on established research). The QuickScreen test is estimated to have a high overall accuracy rate of 93% together with a strong predictive capacity for dyslexia of 97%.
The anonymised data included all candidates who, within a one month period between December 2020 and January 2021, undertook a test via their university, college or workplace assessment process, along with members of the public who requested access to the test via the website.
This group is likely to reflect a reasonable cross-section of the public who accessed the service and consistent with the normal age range of the test (17-55+). Also included was a non-dyslexic control group.
