It is a common but misguided assumption to attribute poor academic performance solely to ADHD. While ADHD can impact focus and attention, leading to difficulties in completing tasks or following instructions, these challenges do not inherently cause the language and literacy deficits that underpin poor academic performance. Individuals with language and literacy challenges may display symptoms of inattention, but these should not be dismissed as mere inattentiveness. Instead, a psychometrically sound assessment is essential to identify the underlying issues accurately.
When investigating poor academic performance, it is crucial to use high-quality language and literacy tests with robust psychometric properties. Tests like the Test of Integrated Language and Literacy Skills (TILLS) are designed specifically to assess language and literacy needs and provide a nuanced understanding of a student’s abilities. In contrast, many widely used educational tests, such as the Woodcock-Johnson Tests of Achievement (WJ-IV) or the Wechsler Individual Achievement Test (WIAT-4) were not created for the purpose of identifying specific language or literacy disorders. Hence, these tools will not adequately capture subtle language deficits or isolate the underlying causes of poor academic performance. As a result, relying on these tests alone can lead to misinterpretations of a student’s needs.
Similarly, The Kaufman Test of Educational Achievement (KTEA) and the Feifer Assessment of Reading (FAR) have notable limitations in their psychometric properties, which reduce their reliability for accurately identifying language and literacy needs. While these tests are commonly used in educational settings, they lack the depth and specificity required to pinpoint the root causes of language and literacy deficits. For instance, the KTEA tends to focus on general academic achievement rather than isolating specific language processing issues, while the FAR’s subtests lack sufficient validity for distinguishing nuanced reading challenges from broader cognitive or attentional difficulties. As a result, these assessments are not ideal for identifying or diagnosing language and literacy disorders.
Misinterpreting Testing Discrepancies
When discrepancies arise between results from a solid test like the TILLS and more general assessments like the WIAT-4, it is erroneous to conclude that the difference is due to inattentiveness or a momentary lapse in focus. This reasoning undermines the validity of the more targeted assessment and shifts the blame onto the student rather than recognizing potential deficits in language or literacy.
Discrepancies often reflect the strengths and weaknesses of the tests themselves. Tools like the TILLS are designed to uncover specific language processing and literacy difficulties, whereas tools like the Wj-IV or the WIAT-4 may provide only a broad overview of achievement without identifying the root causes of performance deficits. Therefore, attributing differences in scores to inattention ignores the real possibility that a student has unmet language or literacy needs.
Language and Literacy Needs vs. Inattention
ADHD can coexist with language and literacy challenges. Language and literacy deficits are rooted in underlying cognitive and linguistic processes, not the external behaviors associated with ADHD. Misattributing these deficits to ADHD can delay appropriate interventions and exacerbate learning difficulties over time.
Accurate identification of language and literacy needs requires assessments that delve deeply into specific areas such as phonological processing, discourse, pragmatics, reading fluency, and comprehension as well as writing. General educational tests may fail to highlight these areas, leading to oversights in diagnosis and intervention. This underscores the importance of using specialized tools that provide detailed insights into a student’s linguistic and cognitive abilities.
Moving Toward Accurate Identification and Intervention
To support students effectively, educators, clinicians, and school teams must recognize the limitations of general educational tests and prioritize assessments with strong psychometric foundations. Tests with solid psychometric properties, such as the Test of Integrated Language and Literacy Skills (TILLS), the Gray Oral Reading Tests, Fifth Edition (GORT-5), or the Clinical Assessment of Pragmatics (CAPS) are far better suited to identify true learning problems and pragmatic needs rather than attributing discrepancies to attentional issues. Using these assessments ensures that interventions address the root causes of academic difficulties and provide students with the targeted support they need to succeed.
In summary, blaming ADHD for poor academic and/or testing performance oversimplifies the issue and risks neglecting true language and literacy deficits. By relying on high-quality, specialized assessments, we can better understand and address students’ needs, ensuring they receive the appropriate support to thrive academically. Misinterpretation of test discrepancies must be avoided, and the focus must remain on identifying and treating genuine learning problems rather than defaulting to inattentiveness as the cause.
