Abstract
This chapter analyzes test data stability and changes over time for various pupil groups. These analyses were based on the data collected for the entire cohort of 3,090 children. Analyses of the individual diagnostic test data, done only for the learning disability group (259 pupils after grade 3–4 testing), are described in Part IV of this book. That part also gives a detailed report by subgroup of the learning disability sample, including the different dyslexia types.
