Ar hyn o bryd mae gennym tua 150 o ysgolion sydd naill ai'n ysgolion babanod yn unig neu’n ysgolion iau yn unig. Dim ond mesurau perfformiad ar gyfer naill ai Cyfnod Allweddol 1 neu 2 fydd yn gymwys ar eu cyfer hwy. Caiff y bandiau ar gyfer yr ysgolion hynny eu cyfrif drwy gymharu'r wybodaeth o'r Cam Allweddol perthnasol â pherfformiad yr holl ysgolion cynradd eraill yn unol â'r mesurau hynny.
Currently we have around 150 schools which are either only infant or junior schools. Only the performance measures for either Key Stage 1 or 2 will therefore apply to them. The band for those schools will therefore be calculated by comparing the information from the relevant Key Stage with all other primary schools’ performance on those measures.
