This paper describes Item Distiller, a tool developed at ETS to aid in the creation of sentence-based test items. Item Distiller enables users to search for sentences that contain specific words, phrases, or grammatical constructions, so that these sentences can be edited to produce finished items. This approach to test authoring is both more efficient than writing items from scratch and more principled, due to its links to item modeling.
