Dyslexia Screening Overview Part 2


This is the 2nd part of an overview of the Universal Screening process. Part 1 dealt with the initial identification of the 20% of children in preschool and primary grades who are likely to fail in the mainstream classroom. You can read this blog here


Dyslexia Screening Overview Part 2


Now I will move on to talk about the comprehensive tests that identify dyslexia.

This visual shows the major components of the reading process. For a reader to be functioning adequately they would need to be competent in all these areas. 


Universal screening focuses on the first three components of reading; phonemic awareness, decoding/phonics, and if age appropriate, fluency. The next level of screening is more detailed and includes comprehension and vocabulary. If this indicates dyslexia is likely, a comprehensive assessment will need to be made by an educational psychologist. 


Comprehensive Assessment

Here I would like to return to the New Jersey screening law that I mentioned in Part 1 of the Dyslexia Screening….


“In the event that a student is determined through the screening conducted pursuant to section 3 of this act to possess one or potential indicators of dyslexia or other reading disabilities, the board of education shall ensure that the student receives a comprehensive assessment of the learning disorder. In the event that a diagnosis of dyslexia or other reading disability is confirmed by the comprehensive assessment, the board of education shall provide appropriate evidence-based intervention strategies to the student, including intense instruction on phonemic awareness, phonics and fluency, vocabulary and reading comprehension. 


A comprehensive assessment would include the following:


❖ A Detailed History

❖ Phonological Processing

❖ Rapid Automatized Naming 

❖ Reading Fluency

❖ Word Reading and Spelling of Real Words

❖ Word Reading and Spelling of Nonsense Words

❖ Morphology Knowledge

❖ Orthographic Coding

❖ Processing Speed and Working Memory

❖ Reading and Listening Comprehension

❖ Expressive and Receptive Oral Language

A future blog will detail each of these components and tests that are used to assess these areas. 


I will use the following visual for the introduction to dyslexia screening. It includes the three tiers of the Response To Intervention (RTI) model used in schools across the nation.

I would like to thank Alison Pankowski, Reading Interventionist and LDTC, and Dr Richard Selznick, for teaching me much about this process. For further reading on this subject, I highly recommend the section on Universal Screening & Early Dyslexia Identification in the NJ Dyslexia Handbook written by Alison Pankowski, as well as Dr Selznick’s book entitled “Dyslexia Screening”
