Ym mis Hydref 2013, cyhoeddais fod adolygiad o’r trefniadau asesu a'r Cwricwlwm Cenedlaethol i'w gynnal fesul dau gam. Mae'r cam cyntaf o’r adolygiad wedi canolbwyntio ar integreiddio llythrennedd a rhifedd i'r cwricwlwm, ac mae'n cynnwys cynigion i adolygu Meysydd Dysgu’r Cyfnod Sylfaen sydd eisoes yn bodoli ar gyfer Sgiliau Iaith, Llythrennedd a Chyfathrebu a Datblygiad Mathemategol. Bydd yr asesiad sy'n cael ei ddatblygu fel rhan o’r Fframwaith yn dibynnu ar gynnwys y ddau Faes Dysgu hyn. Felly, mae'n hanfodol eu bod yn gydnaws â’i gilydd er mwyn sicrhau bod yr asesiad ar ddechrau'r Cyfnod Sylfaen, y tracio blynyddol a'r adrodd ar ddiwedd y Cyfnod yn creu proffil cywir am ddatblygiad dysgwyr.
In October 2013, I announced a two-phase approach to the Review of assessment and the National Curriculum. The first phase of this Review has focused on the integration of literacy and numeracy into the curriculum, and includes proposals to revise the existing Foundation Phase Areas of Learning for Language, Literacy and Communication Skills (LLCS) and for Mathematical Development (MD). The on-entry assessment ladders being developed as part of the EYDAF will be dependant on the content of these two Areas of Learning, and therefore, it is essential that they align to ensure that the on-entry assessment, annual tracking and end of Phase reporting result in an accurate profile of learner progress.
