A £144m fund to pay for 52,000 apprenticeships in Wales will be announced on Thursday.
The cash will be spent on schemes across Wales over the next four years.
The majority of places will be targeted at 16-24 year olds and will allow people to earn a wage while learning new skills through training providers in areas including IT and construction.
It is being funded by £73m in EU funding on top of Welsh government money.
Money will be spent on schemes in Conwy, Anglesey, Gwynedd, Denbighshire, Ceredigion, Pembrokeshire, Carmarthenshire, Swansea, Neath Port Talbot, Bridgend, Rhondda Cynon Taff, Merthyr Tydfil, Caerphilly, Blaenau Gwent and Torfaen.
