The Longitudinal Twin Study of Early Reading
Development is no longer enrolling families. During our enrollment process, the twins met the following requirements:
- Twins must be the same sex
- Twin must be born in Colorado
- Twins must be tested initially in the year before
they start kindergarten (typically age 4 or 5)
- Twins must live in the Colorado Front Range, no further
south than Colorado Springs, and no further north than
Ft. Collins.
During the initial visit families are paid
$100 for their time. Follow up visits occur near the
end of kindergarten, first, second and fourth grade. Families are paid $30 for the follow up visits. Here is a brief overview of the tests we conduct.
