Oherwydd hyn, cyhoeddais ym mis Gorffennaf 2013, y byddai’r Athro Iram Siraj, o  Sefydliad Addysg Prifysgol Llundain yn gwneud archwiliad tymor byr annibynnol  o’r Cyfnod Sylfaen yng Nghymru.  Roedd yr archwiliad hwn a gyhoeddir heddiw yn canolbwyntio ar roi’r Cyfnod Sylfaen ar waith, ansawdd y Cyfnod Sylfaen  a lleihau amrywiaethau.
It is for this reason that I announced in July 2013 that Professor Iram Siraj, from the Institute of Education at the University of London, would be undertaking an independent short-term stocktake of the Foundation Phase in Wales.  The stocktake being published today was very much focused on implementation, quality and reducing variability.
