O dan y Cwricwlwm i Gymru, bydd dysgwyr 14–16 oed hefyd yn parhau i elwa ar y rhannau gorfodol hynny o'r cwricwlwm nad ydynt o reidrwydd yn arwain at gymwysterau, ond sy'n cyfrannu at eu datblygiad, eu llwyddiant a’u camau nesaf. Mae hyn yn cynnwys addysg cydberthynas a rhywioldeb; crefydd, gwerthoedd a moeseg; sgiliau trawsgwricwlaidd gorfodol; a dysgu parhaus ym mhob Maes Dysgu a Phrofiad. Mae'n rhaid inni hefyd gydnabod profiadau ehangach sy’n helpu dysgwr i gyflawni'r pedwar diben.
14–16-year-old learners under the Curriculum for Wales will also continue to benefit from those mandatory parts of the curriculum that do not necessarily lead to qualifications, but which contribute to their development, success and onward progression. This includes relationships and sexuality education; religion, values and ethics; mandatory cross-curricular skills; and continuing learning in each Area of Learning and Experience. We must also recognise wider experiences that contribute to a learner achieving the four purposes.
