Tests in order

Participants take the tests in this order, each with its standard settings. Changing, reordering or adjusting a test makes the study a custom study.

Runs on desktop, laptop, tablet or phone. The app checks each participant's device before the first test. On phones and tablets, each test is compared only with sessions on the same kind of device. A test shows a percentile there once that reference group holds 50 valid sessions in the participant's age band; until then the report shows raw scores and says so.

In a balanced Latin square: 4

The 4 orders of a balanced Latin square, each test as its number in the list above
Order	1st	2nd	3rd	4th
1	1 Alternative Uses Task	2 Design Fluency Test	4 Card Sorting Test (Berg)	3 Verbal Fluency

A study run in this square can measure each test's position effect and the carryover each test leaves on the next.

Numbers are places in the list above. A study started from this battery gives everyone that order, or rotates it and stays this battery.

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.

Grade B: every graded test has at least grade B published evidence. 2 tests have grade A evidence and 2 have grade B.

Grade A needs at least 25 test-retest papers and 25 registered clinical studies for each test. Alternative Uses Task has 8 test-retest papers and 19 registered clinical studies; Design Fluency Test has 22 test-retest papers.

Grade B means at least 8 test-retest papers, and either 5 registered clinical studies or 150 reliability or validity papers.

Grades describe the published research on each task, not this battery or ConductCognition's version of it. Source: ConductCognition test census 0.39.0, counted 31 October 2026 from OpenAlex and ClinicalTrials.gov. See every test's counts or every battery's grade

No test in this battery has a reference group yet, so the report shows raw scores.

In a study, the report lists every score of each test, a percentile where a published norm covers the test and the participant's age, and each session's quality.

Price

Each participant uses one credit, however many tests: $0.99 for academic research or $2.49 for commercial research. Every account starts with 10 free participants, and yearly plans include participants each year. Compare plans
