DAT Perceptual Ability Test (PAT): Sections, Timing, Scoring

The Perceptual Ability Test is the second of four tests in the Dental Admission Test battery. Per the ADA 2026 DAT Candidate Guide (updated 08/04/2026), its 90 items across six subtests measure how accurately you perceive object dimensions and mentally manipulate objects in space.

In 1972, the ADA replaced its manual Chalk Carving Test with the Perceptual-motor Ability Test after validation studies showed visual perception questions predicted performance in dental school technique courses just as well as carving chalk. According to the ADA 2025 DAT User's Manual, a meta-analysis of School Year 2022-2024 dental school data showed PAT scores have a corrected correlation of 0.30 with preclinical operative technique grades and 0.33 with first-year dental school GPA.

You get 60 minutes to answer the 90 PAT items. By our calculation from the ADA 2026 DAT Candidate Guide, 90 items in 60 minutes gives you an average of 40 seconds per question.

The PAT comes immediately after the 90-minute Survey of the Natural Sciences and right before the optional 30-minute scheduled break, meaning you sit through 150 minutes of testing before your break. The total DAT administration time is five hours and 15 minutes, including the optional tutorial, scheduled break, and post-test survey. Read how long the DAT is section by section.

Questions appear one at a time on the computer screen at Prometric. The test timer pauses while the next item loads so loading lag does not count against your 60 minutes.

• Provided materials: Prometric gives you two unlined note boards (without graph lines) and two low-odor fine tip markers. Staff will replace used note boards during the exam upon request.
• No writing early: You may not write on the note boards before the test begins or during scheduled breaks.
• No folding or modifying note boards: You may not fold, bend, distort, or modify the note boards in any manner.
• Hands off the monitor: Candidates may not touch the monitor during the exam, and rulers, paper, pencils, and measuring or magnifying devices are prohibited in the testing room.

The table below pairs each official ADA subtest name and description with the nickname commonly used in prep materials. The ADA strongly encourages candidates to review the separate Perceptual Ability Test instructions PDF on ADA.org/DAT before test day so you do not spend testing time reading directions.

Because official DAT items are copyrighted and confidential, our team wrote the six worked examples below to show the mental steps for each ADA subtest. These items are invented by our team for practice and are not official ADA questions.

Subtest 1: Apertures. Imagine a solid 3D L-shaped block that is 4 units tall, 3 units wide at the base, and 2 units deep from front to back. The vertical arm is 1 unit thick, and the horizontal base arm is 1 unit tall. You must pass this block straight through one of five flat openings without rotating it mid-passage.

How to work it: Check the silhouette along the three straight axes. From the front, the silhouette is a 4-by-3 L-shape. From the left or right side, it is a solid 4-by-2 rectangle. From the top or bottom, it is a solid 3-by-2 rectangle. Eliminate any L-shaped opening with wrong arm thickness, and pick the choice that matches the 4-by-3 L-silhouette or the 3-by-2 top rectangle with exact proportions.

Subtest 2: View Recognition. You are given the top and front views of a 3D block and asked for its end (side) view. The front view shows a rectangle with a step cut out of the upper-right corner. The top view shows a rectangle split vertically by a solid line on the right, plus a horizontal dashed line running through the left section.

How to work it: Align features across views. The upper-right step in the front view creates the solid vertical edge on the right of the top view. The horizontal dashed line in the top view marks a hidden tunnel or recess running from front to back. In the end view, the upper-right step appears as a solid horizontal line at step height, and the hidden recess aligns at its exact height.

Subtest 3: Angle Discrimination. Four angles with unequal leg lengths are rotated in different directions: Angle 1 is 34 degrees, Angle 2 is 31 degrees, Angle 3 is 38 degrees, and Angle 4 is 28 degrees. Rank them from smallest to largest: A) 4 - 1 - 2 - 3, B) 4 - 2 - 1 - 3, C) 2 - 4 - 1 - 3, D) 4 - 2 - 3 - 1.

How to work it: Use the answer choices to compare two angles at a time right at the vertex, ignoring leg length. Three choices start with 4 and one starts with 2. Angle 4 is narrower than Angle 2, eliminating C. Among A, B, and D, the last number is 3 or 1. Angle 3 is wider than Angle 1, eliminating D. Comparing Angle 1 and Angle 2 decides between A and B: Angle 2 is smaller, giving 4 - 2 - 1 - 3 (Choice B).

Subtest 4: Paper Folding. A square sheet (4-by-4 grid) is folded in half top to bottom, then folded in half left to right, leaving a 2-by-2 square in the bottom-right quadrant. One hole is punched in the top-left corner of this folded square (Row 3, Column 3 of the full grid).

How to work it: Unfold in reverse order, treating each crease as a mirror. Undo the second fold (left to right across the vertical centerline between Columns 2 and 3), reflecting the hole at (Row 3, Column 3) to (Row 3, Column 2). Next, undo the first fold (top to bottom across the horizontal centerline between Rows 2 and 3), reflecting both holes into Row 2 at (Row 2, Column 2) and (Row 2, Column 3). The unfolded sheet has a 2-by-2 cluster of four holes in the center.

Subtest 5: Cube Counting. Picture a 3-cube base row running left to right (Left, Middle, Right) flat on a table, with one extra cube sitting on top of the Middle base cube (a 4-cube T-stack). Every exposed face is painted except the undersides resting on the table. How many cubes have 4 painted faces, and how many have 5?

How to work it: Count exposed faces (top, front, back, left, right, never the bottom on the table) from left to right. Left base cube: top, front, back, and left exposed (4 faces). Middle base cube: only front and back exposed (2 faces). Right base cube: top, front, back, and right exposed (4 faces). Top cube: top, front, back, left, and right exposed (5 faces). Tally: one cube has 2 faces, two cubes have 4 faces, and one cube has 5 faces.

Subtest 6: Spatial Relations / 3D Form Development. A flat pattern has four squares in a horizontal row (Squares 1, 2, 3, and 4 from left to right), with Square 5 attached above Square 2 and Square 6 below Square 2. Square 1 has a black circle, Square 2 is solid gray, and Square 3 has a black triangle pointing toward Square 2. Which 3D cube forms when folded?

How to work it: In a 6-square cross net, squares separated by one square in a straight line fold to become opposite faces and can never appear together in a single 3D view. Square 1 (circle) and Square 3 (triangle) are separated by Square 2 (gray), so eliminate any choice showing both the circle and triangle at once. In the remaining choice, verify that the triangle on Square 3 points toward the edge shared with gray Square 2.

Effective March 1, 2025, the ADA replaced the 1 to 30 score scale with a 3-digit scale from 200 to 600 in 10-point increments. All DAT scores sent to ADEA AADSAS are reported on this 3-digit scale, including converted scores from tests taken before March 1, 2025.

Your PAT scale score stands alone. According to the ADA DAT Scores page and User's Manual, the Academic Average is the rounded average of Biology, General Chemistry, Organic Chemistry, Quantitative Reasoning, and Reading Comprehension, and excludes the PAT.

The ADA calculates PAT scores using Item Response Theory (IRT) and the Three-Parameter Logistic (3-PL) model, which accounts for three factors on every item:

• Item difficulty: the percentage of examinees who answer the item correctly.
• Item discrimination: how well the item separates high-scoring and low-scoring examinees.
• Susceptibility to guessing: the impact of guessing on item performance. The DAT does not penalize you for guessing, so never leave a PAT question blank.
• Unscored pretest items: Some PAT questions are experimental pretest items developed by external consultants. They look identical to scored questions and do not count toward your score.
• Score delivery: Unofficial score reports are no longer provided at Prometric test centers. Official results are posted to your DENTPIN account and sent to your selected schools within three to four weeks.

There is no official passing score on the DAT. Each dental school sets its own standards. For full exam benchmarks, see our good DAT score guide. Across 17,430 DAT administrations from March 1 through December 31, 2025, the national mean PAT score in the 2025 DAT User's Manual was 406.84 (standard deviation 66.81). First-time test takers averaged 410.7 (SD 70.8), and repeaters averaged 399.4 (SD 57.7). Across 2025 forms, PAT reliability (KR20) ranged from .90 to .92.

Use the ADA concordance and percentile figures below to compare older 2-digit PAT scores with the 200 to 600 scale.
