About ADHDmetrics.com

ADHDmetrics.com is a clinician-facing reference site focused on the use of objective measurement in ADHD assessment, particularly Continuous Performance Tests. The audience is psychiatrists, psychologists, neuropsychologists, primary-care clinicians, and nurse practitioners who use or are evaluating CPT testing in their practice.

What we do

• Side-by-side CPT comparison — task paradigm, age range, normative sample, FDA clearance, score outputs, pricing transparency for the major commercial CPTs in active use.
• CPT score interpretation calculator — generic-norms-based percentile interpretation for raw CPT scores.
• Reference articles on metric interpretation, integration with practice, and US billing.

Editorial policy

We compare CPT vendors on their merits — task paradigm, validation evidence, normative sample, format, price transparency. We do not rank tools or recommend a single product. Clinicians should evaluate based on their patient population, workflow integration, and the available evidence for their specific use case.

AxonCPT is one of five tools listed in our comparison. Editorially, AxonCPT appears alongside TOVA, Conners CPT-3, QbCheck, and IVA-2 on its merits. The site is operated by the same group as AxonCPT, and outbound links to axoncpt.com carry the rel="sponsored" attribute per our outbound link policy. We do not promote AxonCPT as superior; readers should evaluate it on the same evidence basis as competing tools.

Sources

Reference data is compiled from:

• Publisher product pages and current technical manuals
• Peer-reviewed validation studies (PubMed)
• FDA 510(k) clearance records (where applicable)
• AMA CPT codebook for billing reference
• Standard clinical reference works (Kaplan & Sadock, NICE NG87, AAP/AACAP guidelines)

Update cadence

Vendor data, pricing, and FDA clearance records are reviewed annually. CPT codes are reviewed at AMA codebook publication. Articles are reviewed and updated when underlying evidence shifts.

What we are not

• A diagnostic tool. The score calculator is for educational reference only.
• A purchasing decision service. Vendor selection is the clinician's call.
• A clinical guideline. We summarize and reference; we do not promulgate practice standards.
