Supplemental information
For the summers of 2000, 2010, and 2011, a cut off interval will be used set by a lower and upper cut score. Students falling below the lower score will be assigned to summer school and will be compared with students scoring above that score and not attending summer school under a regression discontinuity design. Students scoring in the cut off interval will be randomly assigned to summer school or no summer school creating an experimental design.
Fidelity of implementation will be monitored through a combination of classroom observation, student attendance, homework completion, and a survey of treatment and control students regarding the summer's activities given at the start of the next school year.
Two-level models will be specified to account for the nesting of test scores within students and the nesting of students within classrooms. Two-level longitudinal growth models (observations within students) will be estimated when data from an entire student cohort is considered as students change academic year classrooms each year and as some students (i.e., non-participants) do not experience a nested classroom structure in the summer. When the focus is estimating literacy outcomes for students receiving treatment (i.e., implementation-by outcome), two-level difference score models will be specified to account for the nesting of students in summer classrooms and to allow for examination of implementation effects on summer literacy change. Piecewise growth models will be applied in instances where student literacy progress is being tracked across one or more academic years and the intervening summers. Single-level regression models will be applied when only changes in literacy across the summer months for treatment and control students are to be estimated.
