Discrete Trial Documentation Pattern
How to prompt LLMs when your clinical approach uses structured, data-driven discrete trial methods, maximizing precision in goals, data recording, and progress analysis.
If your therapy sessions look like structured trials with clear antecedents, target responses, and consequences, your LLM prompts need to speak that language. The model will default to vague, narrative-style output unless you set explicit expectations for data precision.
The Core Pattern
I use a structured, discrete-trial approach. My documentation should reflect specific trial counts, accuracy percentages, cueing hierarchies, and criterion-referenced progress. Frame all goals and notes in terms of measurable behaviors, not narrative descriptions.
How This Changes Output
Without the pattern:
“Student is making good progress with articulation and is becoming more intelligible in conversation.”
With the pattern:
“Across 40 trials targeting /r/ in initial position of words, student achieved 75% accuracy (30/40) at the word level with a visual model. This represents an increase from 60% (24/40) in the previous session. Cueing hierarchy: independent > visual model > auditory model > simultaneous production.”
The second version gives you data you can chart, compare, and defend.
Prompt Modifiers for Discrete Trial Work
- “Include trial counts and accuracy percentages” – forces quantitative output
- “Describe the cueing hierarchy used” – captures the support structure
- “Organize by target and level (word, phrase, sentence, conversation)” – matches your data tracking
- “Include criterion for advancement” – specifies when to move to the next level
- “Note any error patterns observed” – captures clinical detail for treatment planning
