|Figure 3-2: Percentage of children proficient in letter recognition and numbers and shapes at about 4 years old, by race/ethnicity: 2005-06|
NOTE: Percentages reflect children who demonstrated mastery or "proficiency" by achieving a set threshold within a subscale measuring specific skills or abilities. The Early Childhood Longitudinal Study, Birth Cohort (ECLS-B) sampled children born in 2001. Estimates for 4-year-olds pertain to children assessed between 48 and 57 months old. Data on Pacific Islanders are not shown as reporting standards were not met. For more information on race/ethnicity, see supplemental note 1, and for more information on ECLS-B, see supplemental note 3.
