Initial assignment and ongoing participation. Sections labeled sampling represent cases available for randomization or for tracking at the outset of each school year. Participation and follow-up represent students who participated as assigned and completed the end-of-year test battery. Sampling is not indicated for the final year because all available cases from Year 2 were continued in Year 3. Initial randomization (Year 1 assignment) represents the independent variable; we made intent-to-treat assumptions and used a full information likelihood estimator, so analysis included all available data for students randomized at that point. BAU= business as usual group; Tier III IND = individualized Tier III intervention; Tier III STD = standardized Tier III intervention.
