Mae'r cyllid ar gael fel rhan o'r Rhaglen Addysg ac Ysgolion ar gyfer yr 21ain Ganrif.  Mae'r rhaglen hon, sy’n werth £1.4 biliwn, yn ffrwyth cydweithrediad unigryw rhwng Llywodraeth Cymru ac Awdurdodau Lleol, gyda'r nod o greu cenhedlaeth o ysgolion ar gyfer yr 21ain Ganrif yng Nghymru.
The money has been made available as part of the £1.4bn 21st Century Schools and Education Programme, a unique collaboration between the Welsh Government and Local Authorities with the aim of creating a generation of 21st Century Schools in Wales.
