Bob blwyddyn, bydd i ysgolion nifer o ddiwrnodau HMS (Hyfforddiant Mewn Swydd). Mae’r diwrnodau hyn ar gyfer hyfforddiant i staff sy’n bwysig yng nghyd-destun datblygu dulliau addysgu.

Penderfyniad y penaethiaid a chyrff llywodraethu ysgolion yw pennu dyddiadau ar gyfer eu cynnal. Felly, y peth gorau fyddai cysylltu â’r  ysgol dan sylw.

Mae manylion diwrnodau HMS ysgolion i’w gweld isod
