We evaluated the impact of teaching complex grapheme-phoneme correspondences (GPC) derived from the Simplicity Principle to at-risk poor readers in Grade 2 classrooms, using a two-arm dual site matched control trial intervention. Poor word readers (n = 149) were allocated to either a) Simplicity GPC (n= 79) or b) Letter-Name Control (n= 70) small…
