The commission, which manages 126,000ha of woodland owned by the Welsh Assembly Government, said it hoped the six contracts will help secure the future of an industry worth £370m annually to the Welsh economy.
The contracts offer five years of stability to forestry businesses if they train apprentices to NVQ level 2.
They were drawn up after a study in 2009 identified a shortage of contractors able to do chainsaw and wire-rope work in woodlands. The contracts cover work in forests from the Llandovery area in Carmarthenshire to Dolgellau in Snowdonia.
Wales Harvesting & Marketing head Hugh Jones said: "We will use the contracts as a vehicle to generate new entrants into the industry."
