Rydym yn cynnig parhau â'r targed amser aros o 26 wythnos i blant  a phobl ifanc, a'i ymestyn i gynnwys oedolion. Mae'r dull hwn yn cofnodi amseroedd aros o'r atgyfeiriad cyntaf i'r apwyntiad wyneb yn wyneb cyntaf. Mae canllawiau NICE yn cynghori y dylai'r asesiad ddechrau o fewn 13 wythnos, ond gellir cofnodi hyn mewn sawl ffordd wahanol dim ond er mwyn bodloni targedau. O dan ein system gyfredol, yn ystod yr amser aros, caiff tystiolaeth ei chasglu i gefnogi'r apwyntiad asesu ac i lywio penderfyniadau diagnostig.  Os cyflwynir amser aros gorfodol o 13 wythnos, caiff adnoddau arbenigol eu dargyfeirio oddi wrth wasanaethau cymorth ôl-ddiagnostig neu oddi wrth gyflyrau niwroddatblygiadol eraill er mwyn bodloni'r amodau hyn.
We propose to continue with the 26 week waiting time target for children and young people and extend this to adults.  This approach records waiting times from referral to first face-to-face appointment.  NICE guidance advises that there the assessment should commence within 13 weeks, but this could be recorded in many ways just to meet targets.  Under our current system, during the waiting time period, evidence is collected to support the assessment appointment and to inform diagnostic decisions.  If a mandatory 13 weeks waiting time is introduced specialist resources will be diverted away from post-diagnostic support services or from other neurodevelopmental conditions to meet these conditions.
