The ECLS–K also provides much information about kindergarten classrooms and children's reading instructional experiences in the classroom based on the reports of their teachers. Results from the survey can be used to answer questions about the percentages of children who attend kindergarten for a full day or part of a day (half day), the instructional approaches and strategies used in kindergarten classrooms, the amount of attention given to certain reading activities and skills, and whether children's reading gains differ by the type of kindergarten program they attend. The findings are presented separately for full-day and half-day kindergartens.
