Mae gan rieni a disgyblion hawl i wybod pa ysgolion sydd orau yng Nghymru, a chael gwybod sut y mae eu hysgolion hwy yn perfformio. O'r cychwyn cyntaf, rwyf i wedi datgan y byddwn ni'n sicrhau bod y system ar gyfer bandio ysgolion mor dryloyw â phosibl, a hynny o ran y fethodoleg a ddefnyddir yn ogystal â deilliannau’r ysgolion. Wrth gyhoeddi'r data hyn heddiw, rydym yn bodloni'r ymrwymiad hwn.
Parents and pupils have a right to know what is best in Wales and how their schools are performing. I have said all along that we will be transparent about the banding, both in terms of the methodology used and the outcomes for schools. In publishing this data today we are meeting this commitment.
