How the task works
Scan the whole grid and select 1, 2, 3, and onward. Larger grids increase the number of possible locations; time and errors describe performance on that exact grid size.
Schulte Grid
Keep your eyes on the whole grid and select numbers in ascending order as quickly and accurately as you can.
Choose a grid
Larger grids demand a wider field of attention.
Task guide and research
Free Schulte Grid online: a sequential visual-search task
A Schulte table asks you to find randomly arranged numbers in order. This version keeps correct cells visible so the search field does not become easier as you progress.
Research connection
Researchers have adapted Schulte grids to study visual search and attentional allocation. The cited EEG study used a modified dual-color grid, so it supports the visual-search paradigm—not claims about speed reading or general intelligence.
How to interpret your result
Compare sessions only at the same grid size. Faster completion can reflect familiarity with the task as well as a better search strategy; it is not a clinical attention score.
