Ar sail yr holl dystiolaeth hon, nid wyf yn teimlo bod gennym ddata digon cadarn ar hyn o bryd i’w defnyddio i gyfrifo’r bandiau ar gyfer ysgolion cynradd. Mae angen i ni aros nes y bydd gennym ddata sy’n seiliedig ar ddata sydd wedi’u safoni mewn ffordd fwy cyson ac sydd, o’r herwydd, yn fwy cadarn.
On the basis of all this evidence I do not feel we currently have sufficiently robust data to be used in the calculation of bands for primary schools. We need to wait until we have data which are based on more consistently standardised, and therefore, more robust data.
