15 The sample is not appropriate to this review: the parameters for this WWC review specified that students should be in grades K–3 during the time of the intervention; this study did not focus on the targeted grades.
16 Confound: this study included Ladders to Literacy but combined it with other interventions so the analysis could not separate the effects of the intervention from other factors.
17 The disposition is pending development of WWC evidence standards for single subject designs.
