1 Reflects performance on questions on physical sciences, life sciences, earth and space sciences, and scientific inquiry. Possible scores for the science assessment range from 0 to 96. Science was not assessed in the fall of kindergarten.
2 Derived from child’s approaches to learning scale score in fall of the kindergarten year. This score is based on teachers' reports on how often students exhibit positive learning behaviors in seven areas: attentiveness, task persistence, eagerness to learn, learning independence, ability to adapt easily to changes in routine, organization, and ability to follow classroom rules. Possible scores range from 1 to 4, with higher scores indicating that a child exhibits positive learning behaviors more often. Fall 2010 scores were categorized into the four anchor points on the original scale--1 (never), 2 (sometimes), 3 (often), and 4 (very often)--by rounding the mean score to the nearest whole number.
3 The type of nonparental care in which the child spent the most hours. "Multiple arrangements" refers to children who spent an equal amount of time in each of two or more arrangements.
4 A two-parent household may have two biological parents, two adoptive parents, or one biological/adoptive parent and one other parent/partner. A mother-only or father-only household has one biological or adoptive parent only, without another parent/partner. In other household types, which do not include biological or adoptive parents, the guardian or guardians may be related or unrelated to the child.
5 Two or more languages (which could include English) were spoken in the child's home, and the parent respondent was unable to specify which language was the primary one (the one spoken most of the time).
6 Parents' highest level of education is the highest level of education achieved by either of the parents or guardians in a two-parent household, by the only parent in a single-parent household, or by any guardian in a household with no parents.
7 Poverty status is based on preliminary U.S. Census income thresholds for 2010, which identify incomes determined to meet household needs, given family size and composition. For example, a family of three with one child was below the poverty threshold if its income was less than $17,552 in 2010.
8 Includes only children for whom information about both risk factors is available. Excludes children with missing information about parental education or poverty status.
9 High school not completed by any parent or guardian living with the child.
10 Socioeconomic status (SES) was measured by a composite score based on parental education and occupations and household income during the child's kindergarten year.
NOTE: Estimates weighted by W8C8P_20. Estimates pertain to a sample of children who were enrolled in kindergarten for the first time in the 2010-11 school year. The same children were assessed in spring 2012 (when the majority were in first grade), spring 2013 (when the majority were in second grade), spring 2014 (when the majority were in third grade), and spring 2015 (when the majority were in fourth grade). Estimates differ from previously published figures because science scale scores were recalculated to represent the kindergarten through fourth-grade assessment item pools and because weights were adjusted to account for survey nonresponse at each data collection wave, including the latest round of data collection (spring 2015). Race categories exclude persons of Hispanic ethnicity.
