Linear-on-the-fly testing, often referred to as LOFT, is a method of delivering educational or professional examinations.
Competing methods include traditional linear fixed-form delivery and computerized adaptive testing.
Fixed-form delivery, which most people are familiar with, entails the testing organization determining one or several fixed sets of items to be delivered together.
If this exam is high volume, meaning that there is a large number of examinees, the security of the examination could be in jeopardy.
LOFT takes this to an extreme, and attempts to construct a unique exam for each candidate, within the given constraints of the testing program.
