TABLE 5.

Pairwise correlations among parental measures [reading history (ARHQ), math history (AMHQ), and educational attainment] and children’s demographic variables [age, IQ (at baseline), sex, and school information (Title 1 Status)], core academic skills [word recognition (WR) and arithmetic calculation (AR)], and performance on complex tasks [reading comprehension (RC) and problem solving (PS)].
