Scoring+

The main variable in SPAN is the person parameter following a Rasch model for each test form. Adaptive presentation and scoring based on item response theory allow for especially precise measurement of ability.

Person parameters are additionally converted to continuous digit spans. Unlike classical digit spans, these allow decimals so as to more precisely measure differences in personal ability.
