Evidence coverage before you subscribe
The atlas organizes 25 assessments and 399 evidence records. A plan adds comparison, filtering, source receipts, and export tools. It does not supply publisher manuals, test materials, or research that has not been verified.
57 records remain marked “not reported” (including not-applicable entries), 18 preserve source disagreements, and 3 use inherited evidence. These counts include background fields, not just the four categories below. Coverage is separate from clinical quality or suitability.
What is reported for each assessment?
“Reported” means a figure or method-specific summary was checked in a cited source. It may apply only to a particular score, age, language, or sample. An independent review can repeat the manual’s figures without independently validating them. The comparison tools do not establish that the tests or study populations are interchangeable.

How we check evidence
Each numerical record identifies its edition, method, score, population, available denominator, cutoff, page or section, and check date. Missing denominators stay missing. Predictive values, agreement percentages, correlations, and diagnostic sensitivity/specificity are kept distinct. Conflicting summaries remain visible. Earlier-edition or translated results are labeled rather than silently transferred.
Test selection requires the examiner manual, training, and professional judgment. Faculty validation remains pending. Public source availability does not establish endorsement by a publisher, Buros, LEADERSproject, ASHA, or LSU.
