This was a longitudinal study that began in 2013 with 1st and 2nd grade children. These children attended school in the SE. Any child whose parents consented were included. Children were tested each fall for the following 3 years except for the first cohort who were not tested after 4th grade. In each of the following 3 years (after 2013) a new cohort of 1st grade children was added.
All participants came from one school in Florida. Children were in grades 1-4. They were a mixture of races and ethnicities. Their ages ranged from 6- 10 (in our data set age is not a variable, only grade). In all we had 319 participants. There were 161 males and 158 females, 213 students who identified as Caucasian, 47 African American, 27 Hispanic, 10 Asian and 21 Other.
