Speech Therapy Data Sheets: How to Track Trials, Accuracy, and Progress
Speech therapy data turns practice into evidence: count trials, mark each correct or incorrect, and note the level and cues. ASHA says session notes should describe performance in numbers and in words, and IEP progress must be reported regularly. Here is what to record, how to calculate accuracy, and a layout.
What to record each session
ASHA’s guidance on school documentation says notes should be clear enough for any reviewer to see the rationale for treatment, what was done, the student’s current status, and the next steps, and should describe performance both quantitatively and qualitatively. Informal data — check marks during the session — help the clinician compare performance across sessions.1
| Field | Example entry | Why it matters |
|---|---|---|
| Date and minutes | 14 Oct · 20 min | Shows frequency and duration over time |
| Target | /s/ · initial · words | Sound, word position, and level |
| Trials | ✓ ✓ ✗ ✓ ✓ ✓ ✗ ✓ ✓ ✓ | Each attempt marked correct or incorrect |
| Cue level | Verbal model | Accuracy means little without the support used |
| Accuracy | 8/10 = 80% | Compared with the goal criterion |
| Notes | Stronger with “sun” than “sock” | The qualitative side ASHA asks for |

Calculating accuracy
Accuracy on a target is correct productions divided by total trials, times 100. ASHA notes school goals are typically written as percentage accuracy or as the number of trials completed successfully, so record the data in the same form the goal uses.1
For overall severity rather than a single target, SLPs use the percentage of consonants correct (PCC): transcribe a speech sample, count all the consonants, and count how many were correct.2
Why counting trials matters
Trial counts are how you see intervention intensity — dose, frequency, duration, and cumulative intensity. Reviewing data from contrastive intervention studies, one researcher found that greater intensity yields greater treatment outcomes and that intensity changes as intervention progresses and differs by severity.4
The same UK survey also found the intensity typically provided was significantly lower than the literature indicates — a gap that home practice data can help close.3

Treatment notes vs. progress reports
ASHA distinguishes a treatment note, created for each session, from a progress report, which summarizes advancement toward goals over a period such as a quarter. IDEA requires regular progress reports to parents, with qualitative and quantitative information; dismissal is documented when goals are met and services are no longer needed.1
Home practice data
SpeechStep shows which days a family practiced and which words were attempted. An automatic result appears only for R; other sounds are listen-and-compare, so no accuracy number is invented for them.
Frequently asked questions
What should a speech therapy data sheet include?＋
At minimum: the date, the target (sound, position, and level), each trial marked correct or incorrect, the cue level, and the resulting accuracy. ASHA’s school guidance asks that session notes give both a quantitative and a qualitative description of performance.
How do you calculate articulation accuracy?＋
Divide correct productions by total trials and multiply by 100. Seventeen correct out of 20 trials is 85%. For overall severity, SLPs may instead calculate the percentage of consonants correct (PCC) from a transcribed speech sample.
How many trials should a speech session include?＋
More practice generally helps. A UK survey found therapists most often elicited targets 10 to 30 times in single words per session, and a review of intensity data from contrastive intervention studies found that greater intensity yields greater treatment outcomes.
Are data sheets part of the official record?＋
ASHA notes that check marks and other informal data recorded during sessions help the clinician compare performance across sessions and are generally not considered part of the designated record set, while treatment notes and progress reports are formal documentation.
