The purpose of this white paper is to highlight key aspects of technical work behind the update of the TrueNorth English Speaking Test (TNT) from Version C.19.03 to Version D.20.09. This was a significant update in test form. Earlier forms of the TNT including Version C.19.03 utilized a fixed form for Part 1 - Listen and Repeat. In this form, 30 items were presented in a set order from items that targeted ability at Novice (Beginning), Intermediate, Advanced, and Superior (Mastery) levels. Thus, regardless of ability, each test taker would be presented with a battery of items across the full difficulty range in a set order.
