We discuss four issues: (a) many of the lowest achieving students were excluded from participation in Reading Recovery; (b) the control group received a range of different experiences;…

To answer "what works?" questions about policy interventions based on an experimental design, Peck (2003) proposes to use baseline characteristics to symmetrically divide treatment and control group members into subgroups defined by endogenously determined postrandom assignment events. Symmetric prediction of these subgroups in both…
