Advanced Diagnostics & Troubleshooting Flashcards

A student with ADHD presents with average cognitive scores but significantly below-average academic achievement. The diagnostician's report should address which key diagnostic question?

Answer: Whether ADHD-related executive function deficits are sufficient to explain the achievement gaps or whether a co-occurring SLD is present

ADHD can cause academic underperformance, but the diagnostician must determine whether achievement gaps exceed what ADHD alone would predict, signaling a possible co-occurring SLD.

A student's reading comprehension is poor in both silent and oral reading formats, but listening comprehension is also below average. This pattern MOST strongly suggests:

Answer: An underlying oral language/language comprehension deficit affecting both listening and reading

When comprehension is weak across both reading and listening modalities, the deficit resides at the language comprehension level, not solely in print-specific processing.

When a diagnostician identifies a significant strength in long-term retrieval (Glr) on a cognitive battery, how might this strength be leveraged in educational recommendations?

Answer: Suggest instructional strategies that capitalize on mnemonic devices, storytelling, and associative learning

A Glr strength means the student encodes and retrieves associations well, so mnemonic strategies, narratives, and link-based learning are likely to be particularly effective.

Which of the following is the MOST critical ethical obligation when a diagnostician suspects a previous evaluation significantly underestimated a student's abilities due to language barriers?

Answer: Advocate for and conduct a linguistically and culturally appropriate re-evaluation

Ethical practice requires that evaluations be culturally and linguistically appropriate; a diagnostician has an obligation to advocate for a valid re-evaluation when prior assessment was biased.

A diagnostician is comparing a student's reading fluency growth to a local norm benchmark. The student is reading 45 words correct per minute (WCPM) at the end of second grade, while the benchmark is 90 WCPM. This gap is BEST described as:

Answer: A performance deficit indicating the student is reading at approximately half the expected rate

A student reading at 45 WCPM against an end-of-second-grade benchmark of 90 WCPM is performing at approximately 50% of the expected rate, indicating a significant fluency deficit.

When integrating data from multiple sources in a psychoeducational evaluation (tests, observations, records, interviews), what principle should guide the diagnostician's conclusions?

Answer: Converging evidence across sources strengthens diagnostic conclusions; discrepant data requires explanation

A valid diagnostic conclusion requires that multiple independent data sources point to the same interpretation; discrepancies must be explored and explained rather than ignored.

A student referred for emotional/behavioral concerns also shows unexpectedly low scores on phonological processing tasks. The MOST appropriate diagnostic response is to:

Answer: Evaluate whether a co-occurring SLD in reading exists independent of the emotional/behavioral condition

Emotional/behavioral disorders and SLD frequently co-occur, and phonological processing weaknesses warrant a full academic and cognitive evaluation regardless of behavioral referral reason.
