Navigating the Standardized Testing Conundrum: The Good, the Bad, and the Ugly
Over the past week, we delved into Fulcher-Rood et al.'s (2018) findings, uncovering the prevalent use of standardized testing among school-based SLPs. This qualitative study explored the tools SLPs use, the rationale behind their choices, and how data from assessments guide diagnoses for children with speech-language disorders.
In this blog post, we aim to dissect the standardized testing landscape, exploring its benefits, drawbacks, and the complex considerations that SLPs must navigate when choosing assessment tools.
Defining Standardized Testing:
At its core, a standardized test is an assessment tool designed with specific psychometric qualities—reliability and validity. These tests offer consistent administration procedures and typically norm-referenced scores, allowing comparisons to a larger population.
The Good:
The appeal of standardized testing lies in its quantifiable and objective nature. As SLPs, we seek to understand a child's speech and language skills within a developmental trajectory, and comparing them to a normative group seems like a logical approach. Additionally, standardized testing is used in our field and
in many other professions that school-based SLPs work with (e.g., school psychologists and special educators). This gives team members a common ground and language when discussing a child on their collective caseload.
The Bad and the Ugly:
However, the seemingly straightforward path of standardized testing is not without pitfalls. Some common issues include:
Decontextualization: These tests often lack real-world context, assessing language skills in isolation. (3, 6)
Variable Psychometric Quality: Standardized tests may vary in the quality of their psychometric properties. (1, 3, 4, 5, 10, 11)
Lack of Diagnostic Accuracy Metrics: Many tests lack metrics to diagnose disorders (e.g., sensitivity and specificity) accurately. (1, 3, 4, 5, 10, 11)
Arbitrary Cut-off Scores: Research indicates that cut-off scores can be arbitrary and may not reflect the impact of potential disorders. (2)
Cultural and Linguistic Bias: Standardized tests misdiagnose children from diverse backgrounds due to limited representation in normative samples. (4, 5, 11)
The Big Picture:
While standardized tests offer efficiency and comprehensiveness, SLPs must carefully consider their appropriateness for each client. Before deciding if a standardized test should be added to an assessment protocol, these crucial factors should be considered:
Inclusion of diagnostic accuracy measures
Client representation in the norming sample
Client exposure to test stimuli and language
Alignment of test stimuli and language to assessment goals or the language expectations for the client within a variety of contexts
Looking Ahead:
Stay tuned as we continue to dissect the nuances of standardized testing in the coming weeks. Follow us on our social media platforms as we break down the common issues of standarzied testing. Also, subscribe to our newsletter for announcements regarding classes in this area! Our goal is to empower SLPs with the knowledge to select appropriate tests and embrace more authentic, culturally, and linguistically diverse assessment practices.
