FULL DAT EVIDENCE STATUS

Open beta.
Open evidence.

The complete simulation is publicly usable as a free, explicitly unvalidated beta. Independent review, six complete section evidence chains, real representative-device testing, and protocol-governed full-session pilot evidence remain open and are not inferred from public usage.

WHAT THE ZEROS MEAN

Truthful empty evidence
is safer than implied proof.

The automated contracts have already tested deterministic assembly, counts, order, timing boundaries, recovery integrity, raw reporting, planning, and review behavior. Those checks make the system inspectable; they do not substitute for qualified people using representative devices and interpreting real pilot data.

These counts change only when attributable evidence is reviewed and incorporated into a new site checkpoint. Browser-local working records cannot silently change this public status.

BEFORE VALIDATED RELEASE

Five evidence decisions.
None can be skipped.

  1. 01

    Close every section chain

    Biology, General Chemistry, Organic Chemistry, Perceptual Ability, Reading, and Quantitative Reasoning must each bring complete expert decisions, physical-device evidence, and version-matched pilot interpretation.

  2. 02

    Review the joined experience

    Independent integration, assessment, accessibility, and measurement reviewers examine the administration, four section joins, delivery, recovery, reporting, planning, review, and release claims.

  3. 03

    Run five complete-device cases

    Keyboard, screen reader, reflow, mobile touch, forced colors, and reduced motion are tested through the whole day—including transitions, the scheduled break, recovery, and delayed results.

  4. 04

    Analyze complete administrations

    Only exact 280-position sessions enter item and section statistics. Invalid, incomplete, or conflicting sessions are excluded; sample sizes, uncertainty, timing, omissions, and discrimination stay visible.

  5. 05

    Advance one state at a time

    After the evidence closes, the release still moves through separate content-complete, candidate, audit, and publish decisions. No local record or statistic can publish it automatically.

DESCRIPTIVE, NOT OFFICIAL

Difficulty is observed.
Equating is not claimed.

Pilot reporting will show the number of complete administrations, accuracy with uncertainty, omissions, median and interquartile visible time, corrected item–rest correlation, and corrected section–rest correlation.

These are DAT TRAIN pilot statistics. They are not ADA scaled scores, percentiles, national norms, admissions predictions, or automatic item decisions.

AVAILABLE NOW

Use the beta.
Keep the boundary visible.

The complete simulation, readiness maps, and local study workflows are open. Public availability does not convert raw practice counts into official scores or zero evidence counts into approvals.
