Folded Paper
The ETS Paper Folding Test is a standardized measure of spatial visualization that predicts achievement in engineering, chemistry, and mathematics. Parameters adjust to the level and the task.
Example
A generated instance. Parameters such as difficulty, size, and symbol set are adjustable.
Task focus
Each task format is associated with these cognitive categories:
spatial cognition
Understanding and manipulation of spatial relations, orientation, mental rotation of objects.
visual perception
Processing of visual information: recognition of shapes, colors, spatial relations, objects, and faces.
working memory
Temporary storage and manipulation of information for current tasks. Limited capacity (7±2 items).

How to use it
- 1Open the exercise and adjust the difficulty to the student's current level — usually it is better to start slightly easier than feels right.
- 2Read the rules. They are short, usually 10–20 seconds.
- 3Use the generated task as structured educational material, with accuracy and clarity prioritized over speed.
- 4Compare the answer with the reference and leave a human-written comment if the task is assigned through the student cabinet.
Who it's for
- •Educators and tutors — as material for lessons, review, and home practice.
- •Speech, special-education, and development specialists — for children and adults; parameters adjust to the student's level.
- •Parents — to receive clear assignments and leave comments about completion.

Yes. The Folded Paper exercise itself runs in your browser without an account. Sign-up is only needed if you work with clients or want to save progress between sessions.
What is the task focus of Folded Paper?
Primarily — spatial cognition, visual perception and working memory. The full list is in the section above, with short definitions for each function.
How long does one task take?
Most generated tasks are designed for short use in lessons, homework, or individual practice sets. The exact time depends on difficulty and student level.
Can I use Folded Paper with clients?
Yes. In BrainTrainings Academy, Folded Paper can be added to a worksheet set with difficulty controls, student assignment, completion time, and comments.
