Modiwlau datblygu, a fydd yn cael eu datblygu ar sail tystiolaeth gyfredol o ymarfer effeithiol yng Nghymru ac ar draws y byd, fydd elfennau allweddol y rhaglen Feistr. Bydd y rhain yn canolbwyntio ar y tair blaenoriaeth genedlaethol a nodwyd gen i: sef llythrennedd; rhifedd; a lleihau effaith tlodi ar gyrhaeddiad. Cânt eu seilio hefyd ar dri maes craidd arall sydd wedi eu nodi fel blaenoriaethau ar gyfer ANG: anghenion dysgu ychwanegol; rheoli ymddygiad; ac ymarfer myfyriol.
The key elements of the Masters programme will be development modules built upon current evidence of effective practice drawn from Wales and throughout the world. These will be focussed on the three national priorities that I have set out  – literacy; numeracy and reducing the impact of poverty on attainment; as well as three additional core areas that have been identified as priorities for NQTs - additional learning needs, behaviour management and reflective practice.
