There are really several different phases when testing for dyslexia.  There will probably be a short questionnaire even before a screening test is given.  These questions will usually be in the form of a checklist of the signs of dyslexia and ask if the prospective dyslexic is exhibiting any of the signs.  If enough of the signs are present, the next step may be a phone consultation with an educator or psychologist who specializes in dyslexia.  They will ask more questions and determine if an initial screening is warranted or if the problems being displayed are something that will be outgrown.  In many cases, particularly involving younger children, the instruction might be to delay further testing and watch the child's development.

The next phase, what is most properly called a screening test for dyslexia, is given to determine if there is a problem and if the problem is possibly caused by dyslexia.  These tests are very general in nature and may be used to diagnose any of a number of learning disorders, including ADD, ADHD and even autism.  This testing can come in many forms and may be administered online, in a professional's office, or in school.  They can also be done at home either in written form or on the internet using your computer.  In any case, be wary of online tests that are not professionally endorsed as these may not be accurate, often cost money and are used by the website owner to sell more comprehensive testing or a learning tool.

Screening tests can take the form of a list of questions pertaining to the symptoms of dyslexia or computer games which present challenges in which the dyslexic normally struggles.  Either type of screening is acceptable.  Different age groups also require different types of screening tests.  Teens and adults, for example, may not enjoy the computer games type of test, while children, even without dyslexia, may do poorly in written tests.  Some tests are appropriate for only one age group, while others have different versions or different tests for different age groups.

A dyslexia screening test is a very valuable tool for saving time, aggravation and frustration when trying to determine if dyslexia is the problem for someone struggling to learn.  Such tests are the first step in determining an effective learning program for someone whether they are a child, teen or adult.  If further testing is indicated by the screening test, a comprehensive test would be the next step.  Comprehensive testing will determine the degree of disability and will help determine the best way the dyslexic can be helped.  Comprehensive test though, are time consuming, expensive and arduous for the test taker, the test giver, and the concerned parent or loved one awaiting a determination.  They need only be given if indicated by the much simpler screening test for dyslexia.
