How Should We Organize Primary Schooling? Grade Span, School Size and Student Academic Achievement

The researchers proposed to leverage a database of a large urban school district. At the time of the study, the database contained information on more than a million students in grades 1 through 8 for each year over a 7-year period (1995–96 through 2001–02), including extensive data at the individual, classroom, and school levels. The researchers would focus on analyses involving cohorts of third, fourth, and fifth graders followed longitudinally. They were going to use statistical modeling techniques to assess whether school organization characteristics, including school size, grade span, or the number of classrooms, and class size at particular grades related to changes in students' math and reading achievement, as assessed through standardized tests administered annually in third through eighth grades. The large sample size would also allow these analyses to include assessments of whether relationships between school organization characteristics and academic achievement vary depending upon selected student characteristics, including gender, special education status, eligibility for free or reduced-price lunch, race/ethnicity, home language, English proficiency, and country of birth.  The database would also allow for tracking student progress over time and for association with school organization characteristics.
