Self-reflection, screening, and assessment are different things

Self-reflection helps you describe your own reading experiences. Screening is a brief check, used by organizations to decide who might benefit from further assessment, and it cannot provide a diagnosis.[1] Only a diagnostic assessment by a qualified professional can identify dyslexia, and a low score on the first two cannot rule it out.[2]
People often use "test" for three different activities: thinking through your own reading history, taking a short screener, and going through a full assessment. They differ in who runs them, what they measure, and what their results can support. This page explains each one and where this site's questionnaire sits.
Three activities, three different questions
| Self-reflection | Screening | Diagnostic assessment | |
|---|---|---|---|
| Question it answers | What do I notice about my own reading and writing? | Might this person benefit from further assessment?[2] | Does this person meet a stated definition of dyslexia, and what support would help?[3] |
| Who runs it | You, on your own | Often staff in schools, colleges, employers, or support organizations | A qualified assessor, such as a psychologist or, in the UK, a specialist teacher assessor holding an APC[4] |
| What it uses | Your own answers about experiences | A brief checklist, questionnaire, or short set of tasks[5] | History from several sources plus standardized tests[6] |
| Result | Notes in your own words | An indication of possible difficulties[1] | A written report with a diagnostic decision and recommendations[3] |
| Can it diagnose dyslexia? | No | No[1] | It is the route to a formal identification[1] |
Self-reflection
Self-reflection means looking at your own reading and writing experiences in a structured way: what feels slow, what feels comfortable, which situations make reading harder. The questionnaire on this site is a self-reflection tool. It does not screen for, diagnose, or rule out dyslexia or any other condition, and its answers are not compared against any clinical standard. How it was built is described in the methodology.
Self-reflection can still be useful. It can help you put your experiences into words, notice patterns across settings, and decide what to ask about next. If you later speak with an assessor, notes about your history may help: the 2025 UK assessment consensus says that information about whether an adult had literacy difficulties in the early school years supports identification.[6] See preparing for an assessor.
Screening
A screener is a short tool designed to flag who might benefit from a fuller assessment. The Learning Disabilities Association of America describes adult screening as possibly including an informal interview, a brief test, career interest inventories, or a review of medical, school, or work histories.[5] The BDA says screening tests and checklists can give an indication of possible dyslexic difficulties, but cannot provide a diagnosis.[1] AUSPELD, the Australian federation of SPELD associations, says online screening tools cannot provide a formal diagnosis.[7]
Researchers have built and tested adult self-report screeners. One of the best known is the Adult Reading History Questionnaire. Lefly and Pennington reported in 2000 that a revised version showed high internal consistency and stable scores in two adult samples, correlated with reading measures, and helped distinguish adults with and without a reading disability diagnosis in their samples.[8] The samples were adults from a family study of dyslexia (84 people) and parents of 107 children in a reading study.[8]
A more recent study tested the Dyslexia Adult Checklist with 400 adults, half of whom reported having dyslexia.[2] Its authors state that screening tools are not diagnostic and should only be used to signal people for further assessment.[2]
In the UK, the SASC test evaluation committee says it generally does not review materials designed for screening, which are separate from the standardized tests it lists for diagnostic assessments.[9]
Diagnostic assessment
The BDA says dyslexia can only be formally diagnosed through a diagnostic assessment carried out by a certified assessor.[1] The 2025 UK consensus on assessment says multiple sources of information should be combined, and that standardized test results provide objectivity, consistency, and reliability alongside professional judgment.[6] UK report guidance asks assessors to base a conclusion on converging evidence from developmental history, background information, observation, discussion, and test results, tied to a referenced definition.[3]
Who may carry out an assessment depends on the country and sometimes the province or state. In Ontario, Canada, for example, diagnosing a learning disability is a controlled act limited to psychologists and psychological associates registered with the College of Psychologists of Ontario.[10] The details for several countries are in what a professional assessment may involve.
Why the first two cannot establish a diagnosis
- They do not rule out other explanations. Assessment guidance asks assessors to consider vision, hearing, language history, schooling, health, and test conditions before reaching a conclusion.[3]
- They usually do not use standardized, age-normed tests. Assessments rely on such tests to compare a person's performance with a reference group.[6]
- They are not interpreted against a definition by a qualified person. A diagnostic report is expected to reference a definition of dyslexia and explain how the evidence supports or does not support it.[3]
- Their accuracy depends on cut-off choices made by the tool's authors, and every cut-off trades missed cases against false flags.[2]
Why few reported difficulties cannot rule anything out
A low score on a questionnaire or screener does not mean dyslexia is absent. At its original cut-off, the Dyslexia Adult Checklist did not flag about a quarter of the people who reported dyslexia.[2]
There are other reasons too. The 2025 UK consensus notes that in adults, early literacy difficulties may have been missed or masked.[6] The Delphi definition paper adds that dyslexia can be present even when some reading and spelling scores fall in the average range, particularly in adults and people who have had extensive support.[11]
The reverse is also true: reporting many difficulties does not mean you have dyslexia. Reading can feel hard for many reasons, including teaching you did not receive, vision or hearing, language background, health, and fatigue.[3] See dyslexia in adults for how definitions handle this.
When each one fits
- Self-reflection fits when you want to understand your own reading habits, find practical changes to try, or prepare notes before talking to anyone.
- Screening fits when an organization you belong to, such as a college or employer, offers it as a first step toward support. Ask what happens after the result.
- Assessment fits when you need formal evidence, for example for exam accommodations or student funding, or when you want a qualified explanation of a long-standing difficulty. UK consensus guidance says people with reading difficulties should be referred for specialist assessment if there is a consistent lack of progress despite targeted help.[6]
The same consensus also says that everyone who finds literacy difficult should have access to appropriate support and resources, whatever the label.[11] Many reading tools can be tried without any assessment; see reading tools and accessibility features.
Questions to ask about any screening tool
- Who made it, and is it intended for adults?
- Was it tested against confirmed assessments, or against self-reported diagnoses?
- What were its sensitivity and specificity, and in what kind of sample?
- What does the organization do with a result: offer an assessment, offer support, or nothing?
- Who will see my answers, and how long will they be kept?
