The paper highlights problems surrounding the Year 1 Phonics Screening Check that has accompanied the legislative framework for synthetic phonics in English primary schools. It investigates the inclusion of pseudowords and raises questions regarding their generation and categorization, the rationale for their inclusion and the assumption that the early ability to read pseudowords is associated with later success in reading. It draws upon evidence from comparative European orthographic studies employing pseudowords that have implications for the way English pupils learn to read.
