Announcing UK annual revenue growth of 6% to £1.7 billion, E & Y said its offices in Glasgow, Edinburgh, Aberdeen and Inverness continued to make a notable contribution to the firm's growth.
"Despite wider economic uncertainty, graduate numbers in Scotland have increased annually since the onset of the recession and more than 50 are set to join the firm's Scottish offices this year," the group said.
The intake to its school-leaver programme, which was successfully trialled in Aberdeen, is being doubled.
E & Y recently announced its intention to recruit 3700 people across the UK this year - 2400 experienced hires and 1300 student placements - a third of whom will be hired outside of London.
The firm is Official Professional Advisor to the Glasgow 2014 Commonwealth Games and an Official Partner of the 2014 Ryder Cup to be held at Gleneagles.
Jim Bishop, Scotland senior partner at E & Y, said: "Our market-leading oil and gas proposition and the gains we have made in financial services and the public sector have seen us add real value to the firm's growth ambitions.
"We aim to maintain our position as Scotland's biggest professional services firm; an aspiration reflected in the investment we continue to make in our people and our brand."
He said E & Y would continue to support the Scottish ITEM Club, Entrepreneur Of The Year and Independent Director programmes.
