Linear-on-the-fly testing (LOFT) lets you create a unique test for each candidate using items based on domain and psychometric data. This style of testing ensures item exposure is optimised across your bank of items, meaning that individual items are never overexposed or underutilised.
This article explains how to edit your test form, including how to choose your item pool and define your rules for an external optimiser section.
