Our dyslexia and dyscalculia screening tools are informed by decades of peer-reviewed research, clinical best practices, and professional guidelines â but they are not a substitute for a formal diagnosis.
Logifera is not built on intuition alone â it draws heavily on established science. Our questions, scoring logic, and interpretive frameworks are derived from validated studies and clinical consensus. We are transparent that our tool is a screener, not a diagnostic instrument, and we encourage users to seek professional evaluation for any concerns.
Our screening items and reference data are inspired by findings from peer-reviewed journals in psychology, neuroscience, and education.
We look to the diagnostic criteria and recommendations of major professional bodies, such as the DSMâ5 and ICDâ11, to shape our framework â though we are not affiliated with or endorsed by these organizations.
Our algorithms are continuously tested against diverse data sets to improve reliability and fairness, but we do not claim clinical validity for diagnostic purposes.
These references are provided for informational purposes and do not imply endorsement of Logifera by the authors or publishers.
Our screener is inspired by the Diagnostic and Statistical Manual of Mental Disorders (5th ed.) criteria for Specific Learning Disorders, particularly the specifiers for impairment in reading and mathematics. We use these criteria as a conceptual guide, but we do not claim to replicate or replace a clinical diagnosis.
The International Classification of Diseases (11th revision) informs our thinking about symptom clusters and functional impact. Our questions are designed to reflect similar domains, but we are not a diagnostic tool.
We incorporate principles from the International Dyslexia Association standards for screening and assessment, with a focus on evidence-informed practice. Our approach is influenced by these standards but is not formally accredited by IDA.
Our development process takes cues from the National Institute for Health and Care Excellence quality standards for identifying and managing specific learning disabilities. We aim to follow best practices, but we are not NICEâaccredited.
References to DSMâ5, ICDâ11, IDA, and NICE are for informational purposes only. Logifera is an independent screener and is not affiliated with, endorsed by, or certified by these organizations.
Question content, wording, and response options are derived from validated instruments and academic literature, adapted for a screening context.
Scores are interpreted using available normative data and statistical methods (e.g., ROC curves) to help identify potential risk, but these are not diagnostic thresholds.
We regularly review new research and user feedback to improve our screener, always with the understanding that it is a starting point, not a conclusion.
