NNAT3 Nonverbal Assessment 2 — Questions and Answers
Question 1: In a Pattern Completion task, a 3x3 grid shows a diagonal stripe pattern. The bottom-right piece is missing. Which replacement correctly continues the diagonal stripes?
- A piece with horizontal stripes
- A piece with diagonal stripes matching the grid's direction (Correct answer)
- A piece with no stripes
- A piece with vertical stripes
Correct answer: A piece with diagonal stripes matching the grid's direction
Pattern Completion requires selecting the piece that preserves the established visual rule — here, the diagonal stripe direction.
Question 2: A Reasoning by Analogy item shows: Circle is to Sphere as Square is to ___.
- Triangle
- Cube (Correct answer)
- Rectangle
- Cylinder
Correct answer: Cube
A circle is the 2D version of a sphere; a square is the 2D version of a cube.
Question 3: Which NNAT3 task type asks students to determine what a piece of paper looks like when unfolded after being punched with holes?
- Pattern Completion
- Reasoning by Analogy
- Serial Reasoning
- Spatial Visualization (Correct answer)
Correct answer: Spatial Visualization
Spatial Visualization items involve mentally manipulating objects, including paper-folding and hole-punching tasks.
Question 4: A Serial Reasoning matrix has shapes that rotate 45° clockwise across each row. The missing cell is in row 3, column 3. The shape in row 3, column 2 points to the right. Which direction should the missing shape point?
- Right
- Down
- Up-left (diagonal)
- Down-right (diagonal) (Correct answer)
Correct answer: Down-right (diagonal)
Each 45° clockwise step from rightward points to down-right (southeast).
Question 5: The NNAT3 is described as 'culture-fair' primarily because it:
- Is only administered to English-speaking students
- Uses geometric shapes and figures instead of words or numbers (Correct answer)
- Requires prior math knowledge
- Is based on classroom curriculum
Correct answer: Uses geometric shapes and figures instead of words or numbers
Using non-linguistic, geometric stimuli reduces the advantage of any particular language or cultural background.
Question 6: In a Pattern Completion item, a grid displays a checkerboard of black and white squares. The missing piece falls in a position that should be black. A student selects a white piece. This error reflects a failure to:
- Identify shape size
- Apply the alternating color rule (Correct answer)
- Count the number of rows
- Recognize diagonal symmetry
Correct answer: Apply the alternating color rule
The checkerboard rule requires alternating colors; selecting the wrong color means the student did not apply the alternating pattern.
Question 7: Which statement best describes how NNAT3 raw scores are converted for comparison?
- Raw scores are compared directly across age groups
- Raw scores are converted to Nonverbal Ability Index (NAI) scores with a mean of 100 and SD of 15 (Correct answer)
- Raw scores are converted to letter grades
- Raw scores are divided by the total number of questions only
Correct answer: Raw scores are converted to Nonverbal Ability Index (NAI) scores with a mean of 100 and SD of 15
The NAI is a standardized score (mean=100, SD=15) that allows comparison across different age groups.
