The Longitudinal Twin Study of Early Reading Development is currently being conducted in Australia, Norway, and the United States. Researchers at universities in these locations are collaborating to look for genetic, familial, and cultural influences on reading development.

Identical and fraternal twins are being tested in preschool for pre-reading skills, and after kindergarten, first grade, and second grade for the development of early reading, spelling, and related cognitive skills.
