Mae’r gwerthusiad yn canfod bod y Gwasanaethau Awtistiaeth Integredig wedi arwain at ragor o asesiadau a gwasanaethau diagnosis ar gyfer oedolion, ac wedi gwella eu safon. Mae nifer a safon asesiadau a gwasanaethau diagnosis ar gyfer plant wedi gwella hefyd, drwy sefydlu Gwasanaethau Niwroddatblygiadol newydd i blant a phobl ifanc. Mae sefydlu’r Gwasanaeth Awtistiaeth Integredig wedi tynnu sylw at alw nad oedd yn cael ei fodloni yn flaenorol am wasanaethau awtistiaeth. Fel sy’n wir ar gyfer gwasanaethau Niwroddatblygiadol hefyd, mae’r galw am wasanaethau wedi arwain at (neu ychwanegu at) restrau aros hir. Ar hyn o bryd, mae’r gwerthusiad yn nodi bod y rhagolygon ar gyfer y dyfodol yn galonogol.
The evaluation finds that the IASs have increased the capacity and quality of assessment and diagnosis services for adults, and improvements to the capacity and quality of children’s assessment and diagnosis services have been made, through the establishment of new children and young people’s Neurodevelopmental Services. The implementation of the IAS has drawn attention to previously unmet demand for autism services and, like ND services, the demand for services has produced (or added to) long waiting lists. At this stage, the evaluation reports that prospects for the future are encouraging.
