Data
Test batteries by published evidence
A battery takes the grade most of its tests reach. A minus means some tests have a lower grade, and a battery is never more than one letter above its weakest test. The study builder grades every study the same way. A test's grade counts the published research on it: papers on its test-retest reliability and registered clinical studies that use it as an outcome.
Every battery, strongest evidence first
Grade A first, then A−, B and on down; within a grade, the batteries the fewest tests and papers from grade A come first. Grade A needs at least 25 test-retest papers and 25 registered clinical studies for each test; the last column gives what each test below it has.

How batteries are graded
A battery takes the grade most of its tests reach. A minus means some tests have a lower grade, and a battery is never more than one letter above its weakest test. A test's grade comes from the ConductCognition test census: papers that report its test-retest reliability, papers on its reliability or validity, and ClinicalTrials.gov studies that use it as an outcome.
Grades describe the published research on each task, not a battery or ConductCognition's version of it.
Each test's counts are in the full table, how they are made is in the method, and each battery's tests, guide and example report are in the battery catalog.
Source: ConductCognition test census 0.39.0, counted 31 October 2026, 2 November 2026 and 8 November 2026 from OpenAlex and ClinicalTrials.gov.
- A
- At least 25 papers report its test-retest reliability and at least 25 registered clinical studies use it as an outcome
- B
- At least 8 test-retest papers, and either 5 registered clinical studies or 150 reliability or validity papers
- C
- At least 2 test-retest papers, 30 reliability or validity papers or 3 registered clinical studies
- D
- Little published measurement evidence found
