East Ayrshire began the Scottish pilot three years ago and it was extended in the past session to Glasgow, West Dunbartonshire and Dundee in a pound;21.6 million initiative that can pay families up to pound;40 a week.
Richard Barron, depute director of education in Glasgow, said: "It has been beneficial and more people have benefited and got more money than they would have from the previous bursary allowances." Schools were happy with it. Pupils make a commitment to attend regularly and study harder through a learning agreement.
Launching the scheme, Wendy Alexander, former Lifelong Learning Minister, said education was even more important as a passport to success in later life. A third of leavers still quit at 16.
A Scottish Executive spokesman said the scheme was currently being evaluated.
