But how do you find the children who might need help? It’s simple with the Quick Interactive Language Screener™: English—Spanish (QUILS™: ES), a one-of-a-kind tool that helps you evaluate whether bilingual children are making language progress appropriate for their age group.

Administered during the regular day, typically one child at a time in a quiet area of the classroom, the QUILS: ES is a helpful addition to kindergarten entry assessments (KEAs) and an ideal tool for use in individual classrooms or centers. The format ensures standardized delivery for each child, while automatically generated scores save time for busy teachers and other practitioners—providing cut scores by age level, standard scores, percentile ranks, and reports to share with colleagues and families. And this game-like interactive measure is so much fun, children might even ask if they can do it again!
