Developing an Understanding of Repeating Patterning

The goal of the current paper is to consider potential operationalizations of repeating patterning understanding, as well as expand the toolkit for measuring repeating patterning understanding. The Early Patterning Assessment (EPA) is a research instrument that can be given online or in person, using mostly selected-response items. Across four rounds of data collection in the U.S. (n = 244) and one study in Turkiye (n =107), the repeating patterning measure was a reliable measure for 4-7-year-old children, with scores increasing with age. It was also easier and faster to administer than past assessments that used constructed response items.
