Gall ysgolion drefnu cynnal yr asesiadau personol ar adeg a fydd yn fwyaf buddiol ar gyfer eu dysgwyr yn eu tyb nhw, ac fel rhan o'u trefniadau asesu ehangach. Gall ysgolion hefyd gynnal yr asesiadau ddwywaith er mwyn adolygu newidiadau a chynnydd a welir yn sgiliau eu dysgwyr yn ystod y flwyddyn. Defnyddir yr wybodaeth o'r asesiadau i helpu ysgolion i gynllunio cynnydd yn y sgiliau trawsgwricwlaidd sydd eu hangen ar ddysgwyr er mwyn manteisio ar rychwant cwricwlwm yr ysgol. Hoffwn bwysleisio mai diben yr asesiadau yw helpu dysgwyr i wneud cynnydd; ni luniwyd yr asesiadau i'w defnyddio at ddibenion atebolrwydd, ac ni fwriedir eu defnyddio at ddibenion o'r fath, ar unrhyw lefel.
Personalised assessments are available for schools to schedule at a time they consider most beneficial for their learners and as part of their wider assessment arrangements – and schools have the option of using them twice in order to review in-year changes and progress in their learners’ skills.  The information from the assessments supports schools in planning progression in the cross-curricular skills essential for learners to access the breadth of a school’s curriculum. And I would like to emphasise here that the purpose of the assessments is to support learner progress; they are not designed or intended to be used for accountability purposes at any level.
