Adleisiwyd y safbwynt hwn yn asesiad polisi cyflym y Sefydliad ar gyfer Cydweithrediad a Datblygiad Economaidd (OECD), "The Welsh Education Reform Journey". Un o argymhellion yr adroddiad oedd bod angen i Gymru symud tuag at system asesu, gwerthuso ac atebolrwydd newydd sy'n cyd-fynd â chwricwlwm yr 21ain ganrif.
Ensuring coherence was a key finding in the Organisation for Economic Co-operation and Development’s (OECD) rapid policy assessment “The Welsh Education Reform Journey”. One of the report’s recommendations was the need for Wales to move towards a new system of assessment, evaluation and accountability that aligns with the new 21st century curriculum.
