Performance tests — scored where the norms are public, integrated where they aren't.
BrainScribe converts raw scores against published normative datasets where the literature is open. For publisher-proprietary tests (WAIS, WMS, CVLT, BVMT-R, D-KEFS), the clinician scores with their own licensed materials and enters the result; BrainScribe records provenance and integrates it with the rest of the assessment.
Performance scores, on a named distribution.
BrainScribe converts raw test scores against the normative dataset that fits the patient and renders a domain-level profile. The source, the stratum and the conversion direction stay visible. The clinician verifies before anything enters a draft.
Domain profile
Compiled from eight performance tests across five domains. Reverse-scored measures (time, errors) handled before plotting.
Raw in. Scaled, z, percentile out.
The slider runs against published Animal Fluency norms (Tombaugh, Kozak & Rees, 1999, Archives of Clinical Neuropsychology, age 60–69 with ≥ 12 years of education). Move it to see raw input map to z and percentile in real time, with the descriptor band shifting at the published cut-points. The conversion logic is identical for every test BrainScribe computes against published norms.
Two tiers: scored, and integrated.
Performance tests fall into two groups. Where normative data is published in the open literature, BrainScribe scores the test against the named dataset with source, stratum and scoring direction preserved. Where norms live in a publisher's commercial manual, the clinician scores the test using their own licensed materials and enters the raw and standardised values; BrainScribe records the provenance and integrates the result with the rest of the assessment record.
AScored against published literature
BScore-entry — clinician brings the publisher's scoring
Score-entry tests are integrated into the same record as the public-norm tests. The clinician's scoring stays in the publisher's tool; BrainScribe records the raw, the standardised value, the normative stratum cited, and any qualitative descriptor — and uses them in the same way during draft assembly. A formal publisher relationship — a publisher-licence-style integration where the practitioner brings their own publisher entitlement and BrainScribe handles the workflow — is on the roadmap and would extend tier A.
Three rules that keep the conversion honest.
Reconciliation tolerance
Raw → scaled → z → T → percentile must reconcile to within a half-unit. Outside that tolerance, the field surfaces a soft warning rather than silently passing values into the draft.
Reverse direction handled
Time-based and error-based measures (Trail Making, Stroop time, Bells omissions) are inverted before they contribute to a domain score. The descriptor always reflects clinical direction, not arithmetic direction.
Provenance preserved
Every converted score carries its source — the manual citation, the stratum, the sample size — into the assessment record. If a referrer queries a score, the source is visible to the clinician before they answer.
Verbal list-learning was mildly impaired, with performance at the 12th percentile on the CVLT-3 (T = 38).
