Yn dilyn pleidlais unfrydol gan Aelodau’r Cynulliad ar 19 Hydref 2016, cyhoeddodd y Llywydd ei bwriad i sefydlu Senedd Ieuenctid i Gymru.  Ers hynny, mae Comisiwn y Cynulliad wedi gweithio gyda Grŵp Llywio’r Senedd Ieuenctid i ddatblygu ac ymgynghori ar y cynnig i sefydlu Senedd Ieuenctid. Cynhelir etholiadau Senedd Ieuenctid Cymru ym mis Tachwedd 2018 er mwyn ethol 60 o aelodau ifanc. Bydd pobl ifanc yn ethol 40 o’u cyfoedion, a chaiff yr 20 o aelodau eraill eu hethol gan sefydliadau sy’n bartneriaid. Bydd hyn yn sicrhau bod grwpiau amrywiol o bobl ifanc o bob rhan o Gymru yn cael eu cynrychioli.
Following a unanimous vote of support from Assembly Members on 19 October 2016, the Llywyd announced her intention to establish a Welsh Youth Parliament.  Since then the Assembly Commission has worked with a Youth Parliament Steering Group to develop and consult on a proposal for a Youth Parliament. Elections to the Welsh Youth Parliament of the 60 young members will take place in November 2018, with young people electing 40 of their peers and the remaining 20 elected by partner organisations. This will ensure representation from diverse groups of young people from across Wales.
