Construct

Percent increase calculation.

Why this construct matters

Program metrics often report percent change.

Selection research treats cognitive ability among the strongest predictors of job performance (Schmidt & Hunter, 1998; Sackett et al., 2022). This item contributes a timed behavioral sample of the construct above—not a medical or neurological measurement.

Scoring

RuleValue
Correct**+2.0** accuracy points
Speed bonus**+0.2** if correct and response time ≤ **25 seconds**
Item window**45 seconds**
Form maximum composite**110** (accuracy max 100 + speed index max 10)

Speed bonus (pro–test-taker)

The speed component is optional upside for fast correct work. Slow correct answers still receive full accuracy credit. Incorrect answers never receive speed credit. This design rewards speed of accurate thinking relevant to many jobs without punishing careful correct solvers on the accuracy scale.

Use limits
