GDAP: Glaspey Dynamic Assessment of Phonology — A Modern Standard in Speech Production

Revolutionize your assessment process with the GDAP, the first standardized dynamic assessment of speech production and stimulability. Unlike static tests that only provide a “correct or incorrect” snapshot, the GDAP measures the process of learning. It identifies exactly how much support a child needs to succeed, providing a nuanced look at emerging skills and long-term potential.

The Power of the 15-Point Cueing Hierarchy

The heart of the GDAP is its unique 15-point scoring matrix. By tracking the specific scaffolding levels a child requires, you gain a sensitive measure of progress that traditional tests miss.

• The Scoring Logic: A score of 1 represents total independence in connected speech, while higher scores indicate the specific level of clinical cueing required for the child to produce the target.

• The Decision Matrix: This standardized system guides you through a progression of prompts—from simple instructions to intensive tactile or verbal cues—systematically varied across linguistic contexts.

Comprehensive & Evidence-Based

The GDAP covers 49 items to ensure no stone is left unturned in your evaluation:

• Phoneme Coverage: Includes 22 initial phonemes, 21 final phonemes, and 4 blends.

• Sound Classes: Comprehensive representation of Glides, Nasals, Stops, Velars, Stridents, Interdentals, and Liquids.

• Linguistic Environments: Each item is tested across three levels—Single Word, Two-Word Sentence, and Connected Speech—using vibrant, child-friendly imagery.

Clinical Tip: Tracking “The Zone of Proximal Development”

The GDAP is the perfect tool for demonstrating “micro-progress” to parents and school districts. A child might still be “incorrect” on a standardized static test, but the GDAP can show they have moved from needing a level 12 cue (maximal) to a level 5 cue (minimal). This data is invaluable for writing specific, measurable IEP goals and proving the efficacy of your therapy!
