The Spelling Piano app technology enables at least 90% of children to pass the PSC by the end of Reception. It frees up time to focus on reading for pleasure rather than on learning additional GPCs. Passing the PSC does not correlate with improved reading comprehension in KS2, so more is needed (Bradbury, 2019; Gibb, 2022; Wyse & Bradbury, 2022). However, passing it early and easily means we can spend more time on decoding within meaningful context.
Within the Speedie Readies system the Monster Spelling Piano app sets up a learning environment in which children can start the Monster Mapped One, Two, Three and Away! readers.
