Perceptual Ability

Two strings, side by side. Same, or different? The strings are shaped like the things a dispatcher actually reads under time pressure: a plate, a callback number, a unit ID. A single swapped digit is the whole test.

Practice tool. Every plate, phone number, and unit ID here is fictional and every phone number uses the 555 convention. This is not a commercial testing instrument, is not affiliated with or endorsed by any test vendor or agency, and does not reproduce any real test's content. It does not state a passing score, because passing standards are set by the hiring agency and this tool does not know yours.
