O ganlyniad, lluniwyd ffordd newydd o ddarparu’r CPCP, fel y’i nodir yn Rheoliadau Cymwysterau a Chofrestru Prifathrawon (Cymru) (Diwygio) 2011. Y prif newid oedd gwneud yr CPCP yn asesiad trylwyr o ymarfer ymgeiswyr gan weithwyr proffesiynol profiadol, a hynny yn erbyn y Safonau Cenedlaethol ar gyfer Prifathrawiaeth a oedd mewn grym ar y pryd. Roedd yr ymchwil a gynhaliwyd gan Estyn ac eraill wedi dangos nad oedd yr hen fodel yn gweithio, a bod angen ei newid.
This resulted in a new approach for the NPQH in Wales as detailed in the Headteachers’ Qualifications and Registration (Wales) (Amendment) Regulations 2011. The main change was to make the NPQH a rigorous practice based assessment of practitioners by experienced professionals against the then National Standards for Headship. Research by Estyn and others had demonstrated that the old model of delivery was not working and change was needed.
