Study Meta-data

Description

The Early Education Longitudinal Study (EELS) tracks children, who were ages 3-5 in the initial year of the study, for a period of three years, resulting in a cross-sequential longitudinal data base.  The Focus of the study was to follow the development of literacy skills among young children from a variety of home and communication backgrounds.  The study was modeled after the Pre-Elementary Education Longitudinal Study (PEELS) conducted by the National Center for Special Education Research.  Like PEELS, EELS consisted of direct assessments of the participants language, reading, and intellectual development over the time of the study, as well as comprehensive data on family background and home literacy practices, indirect assessments using behavioral checklists.
