Datblygwyd y Fframwaith ar y cyd â phartneriaid ledled Cymru drwy Grŵp Gorchwyl a Gorffen oedd yn cynnwys partneriaid o’r trydydd sector, sefydliadau statudol a thimau polisi allweddol Llywodraeth Cymru. Ategwyd hyn gan dystiolaeth saith grŵp ffocws a rhanddeiliaid oedd yn cynrychioli’r holl nodweddion gwarchodedig, ac arolwg ar-lein a dderbyniodd 167 ymateb o bob cwr o Gymru. Mae Llywodraeth Cymru hefyd wedi comisiynu gwaith ymchwil gan Brifysgolion Caerdydd a Manceinion i’r hyn sy’n cymell y rheini sy’n cyflawni troseddau casineb. Caiff canlyniadau’r gwaith hwn eu cyhoeddi ochr yn ochr â’r Fframwaith. Daeth tystiolaeth i’r amlwg hefyd gan Brosiect Troseddau Casineb Cymru Gyfan trwy Race Equality First a Phrifysgol Caerdydd, ac mae eu canfyddiadau cynnar yn ffurfio rhan o sail dystiolaeth y Fframwaith.
The Framework has been driven with partners across Wales through a Task and Finish Group including third sector partners, statutory organisations and key Welsh Government policy teams. This has been supplemented with evidence from seven focus and stakeholder groups across the protected characteristics and an on-line survey with 167 responses from across Wales. Welsh Government has also commissioned research into the motivations of perpetrators through Cardiff and Manchester Universities whose findings will also be launched alongside the Framework. There has also been emerging evidence from an All Wales Hate Crime Project in Wales through Race Equality First and Cardiff University, whose early findings have been included in the evidence base of the Framework.
