Literacy Part 2: Assessment

Updated: Aug 16, 2022

Updated March 2022

Before I started learning more about literacy, it seemed so ominous. If terms like specific learning disability in reading, dyslexia, or reading comprehension difficulties make your head spin, go check out the first post of this blog series here. Take a quick read about background information about literacy and then come back to learn about warning signs and assessment.

There is no one sure way of identifying young children who will go on to develop reading and writing difficulties. That being said, there are known indicators (sometimes called "red flags") which should be monitored through a child’s preschool and early school years. The greater the number and severity of risk factors, the higher the likelihood of a child going on to have difficulties. Ideally, a child who is noted as having a high number or severity of risk factors should seek a full literacy assessment within their grade 1 year. The earlier a child is identified and begins intervention, the better their outcomes!

So, what are these indicators? Research has noted the following as risk factors for future reading difficulties:

-Poor phonological awareness. This is the ability to recognize and manipulate sounds within words and includes skills like blending separate sounds together or rhyming.

-Family history of reading/writing difficulties or learning disabilities. 40-60% of children with first-degree relative with reading difficulties go on to have reading difficulties, as compared to 6-14% who do not.

-Poor knowledge of letter names and the sounds they make (phonics).

-Speech sound disorders (SSDs). 30-77% of children with SSDs have reading difficulties.

-Poor oral vocabulary knowledge. Although these are not strongly linked, it is an area to monitor as it has been noted that:

*In early elementary years, it is linked to difficulties understanding what they read (SRCD).

*In later elementary years, this is linked to difficulties with word-reading.

-Poor morphological awareness. This is the ability to recognize and use grammatical markers (e.g., “ed” endings on words like “jumped”).

-Many different types of hearing loss.

-Poor cognitive skills including rapid automatic naming, short-term memory, working memory or executive functioning.

-Diagnoses including childhood apraxia of speech (CAS), attention deficit hyperactivity disorder (ADHD), and autism spectrum disorder (ASD; higher rates of SCRD).

Once a child has been identified as ‘at risk’ for reading difficulties (as per factors above) or been noted as struggling with grade-expected reading or writing, a full literacy assessment should be completed. Although schools in Ontario provide benchmark evaluations of students’ reading and writing skills, teachers and school staff do not have the time resources to complete full literacy assessments on all struggling children. Remember that 20% of children have dyslexia - in a school of 500 children, that is approximately 100 children! In Ontario, a speech-language pathologist working in private practice can complete a comprehensive literacy assessment. It is recommended to check your health insurance benefits under “Speech Language Pathology” or “Speech Therapy” as many plans have coverage for all or part of this assessment.

Research shows that the following should be included in a comprehensive literacy assessment:

-Phonological awareness skills including blending, segmenting and letter-sound correspondences. This helps to determine whether a child may need direct teaching on these skills but also how quickly we expect a child to move through explicit reading and writing instruction.

-Single-word reading of both real and nonsense words. Single word reading removes any context that a child can be using to read words and taxes their phonological knowledge (knowledge of rules for sounding out words). In addition, nonsense words force a child to use phonological knowledge rather than visual memory. For example, some children can read the word “big” because they have seen it so many times and remember it as a whole, but the nonsense word “dix” requires a child to use decoding skills or ‘sounding it out’.

-Single-word spelling of real words.

-Oral reading on passages to look at accuracy, fluency (rate), prosody (phrasing and expression when reading aloud), and reading comprehension.

-Oral use and understanding of vocabulary.

-Listening comprehension of sentences and/or passages.

So to wrap up, we have now reviewed both background information about literacy, warning signs for later reading difficulties, as well as areas to include in a comprehensive literacy assessment. Up next, tips and strategies for literacy intervention!
