IGDIS stands for Individual Growth and Development Indicators; used to check early reading and literacy skills in preschoolers before they start kindergarten. Which age group is it designed for?

• A. Infants
• B. Preschoolers before starting kindergarten
• C. High school students
• D. Adults

Answer: (B)

IGDIS is an early literacy screening tool used with children who have not yet started kindergarten to gauge growth in key pre-reading skills. It targets preschoolers before they enter formal school, because those prior-to-kindergarten years are when foundational skills like print awareness, letter knowledge, and early phonological awareness are developed and tracked.

That’s why the correct group is preschoolers before starting kindergarten. It isn’t intended for infants, high school students, or adults, whose literacy needs and developmental stages are far outside the scope of this preschool-focused assessment.
