Access to HE Grading Standards (for learners registered from 1st August 2024):

  • 1 - Knowledge and Understanding
  • 2 - Subject Specific Skills
  • 3 - Transferrable Skills
This is a graded unit and all three grading standards must be used in line with the Access to HE grading scheme.

Disgrifyddion Graddau Mynediad i AU (for learners registered before 1st August 2024):

  • 1 - Dealltwriaeth o’r pwnc
  • 2 - Rhoi gwybodaeth ar waith
  • 4 - Defnyddio gwybodaeth
  • 5 - Cyfathrebu a chyflwyno
  • 7 - Ansawdd
Ni ddylid ond dyfarnu gradd am gyflawni’r uned hon os yw’n cael ei chynnig fel rhan o raglen astudiaeth ar gyfer y Ddiploma Mynediad i Addysg Uwch.

Dulliau Asesu:

Unit Assessment Requirements are not prescribed. They remain as a recommended approach to assessment where they still reflect the unit specification.
From September 2021, centre devised assessments are permitted for all units on all Agored Cymru Access to HE Diplomas.
All assessment evidence completed As part Of an Agored Cymru Access To HE Diploma Is subject To external moderation.

Gwybodaeth Asesu:

AC 3.2 at least 3 absorbers
AC 3.3 Alpha, beta and gamma.
AC 6.1 at least 3 sources
AC 6.4 at least 3 different doses of radiation

Os nad yw wedi’i nodi’n benodol yn y wybodaeth asesu, mae datganiad lluosog mewn unrhyw faen prawf asesu yn golygu o leiaf dau.

Gofynion Aseswyr:

Nid oes unrhyw wybodaeth ynghylch gofynion penodol ar gyfer aseswyr i’r uned hon. Dylai canolfannau ddewis aseswyr sydd wedi cael eu hyfforddi mewn asesu, ac sydd â chymhwysedd sy’n benodol i’r pwnc i asesu ar y lefel hon.
