1 Includes students with missing kindergarten entry status information.
2 A child who enrolled in kindergarten for the first time in 2010-11 is classified as an early, on-time, or delayed kindergarten entrant depending on whether the parent reported enrolling the child early, enrolling the child when he or she was old enough, or waiting until the child was older relative to school guidelines about when children can start school based on their birth date. A child is classified as a kindergarten repeater if the parent reported that 2010-11 was the child’s second (or more) year of kindergarten.
3 Reflects performance on questions measuring basic skills (print familiarity, letter recognition, beginning and ending sounds, rhyming words, and word recognition); vocabulary knowledge; and reading comprehension, including identifying information specifically stated in text (e.g., definitions, facts, and supporting details), making complex inferences from texts, and considering the text objectively and judging its appropriateness and quality. Possible scores for the reading assessment range from 0 to 141.
4 Reflects performance on questions on number sense, properties, and operations; measurement; geometry and spatial sense; data analysis, statistics, and probability (measured with a set of simple questions assessing children’s ability to read a graph); and prealgebra skills such as identification of patterns. Possible scores for the mathematics assessment range from 0 to 135.
5 Reflects performance on questions on physical sciences, life sciences, environmental sciences, and scientific inquiry. Possible scores for the science assessment range from 0 to 87. Science was not assessed in the fall of kindergarten.
6 The approaches to learning scale is based on teachers' reports on how students rate 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 on the scale range from 1 to 4, with higher scores indicating that a child exhibits positive learning behaviors more often.
NOTE: Estimates weighted by W7C7P_20. Estimates pertain to a sample of children who were enrolled in kindergarten 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), and spring 2014 (when the majority were in third grade). Estimates differ from previously published figures because reading, mathematics, and science scale scores were recalculated to represent the kindergarten through third-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 2014).
