Patterns of Literacy Achievement

Preliminary Examples

Below are preliminary examples of 3-Level HLM models conducted by SII researchers for patterns of literacy achievement in CSR programs. The figures below show data results for literacy achievement patterns. Example output for the model analyses can be found here (example 1, example 2, example 3). A discussion of the results appears in the section entitled, Patterns of Literacy Achievement in Schools. Student reading and mathematics achievement data files for all cohorts can be found here.
