Byddai opsiynau eraill, gan gynnwys gofyn i ganolfannau bennu’r graddau heb gymorth, wedi ei gwneud yn ofynnol i’r canolfannau hynny ddylunio deunyddiau asesu, eu profi o safbwynt cydraddoldeb a hygyrchedd, sicrhau cysondeb ar draws canolfannau (a gwylio rhag gor-asesu), datblygu a phrofi cynlluniau marcio, ac yna fod yn gyfrifol am apelau mewn perthynas â’r rhain.
Alternative options, including unsupported centre assessment grades, would have required centres to design assessment materials, test them for equalities and accessibility, ensure a mechanism to provide consistency across centres (and protect against over-assessment), develop and test marking schemes, and then be responsible for appeals in relation to these.
