Mr Scott said Scotland's future depends on investment in children
No child in Scotland would be "left behind" by the Liberal Democrats, according to Scottish party leader Tavish Scott.
Campaigning in East Dunbartonshire he said less money was being invested in the right areas by Labour.
Mr Scott said the Lib Dems would "invest in education, invest in early years and make sure that those from the toughest backgrounds have the chances".
Mr Scott also stressed his support for a clampdown on tax loopholes.
The party leader visited Merlwood Nursery in Lenzie to support local candidate Jo Swinson, and said the Lib Dems were committed to " a fair start for every child".
He said: "It is of real concern that so many kids from bad backgrounds don't have a real chance for the future in Scotland today."
He continued: "We want to make sure that no child is left behind in Scotland and in these last few years under Labour down at Westminster we have seen less money being invested in the right areas so we want to turn that around.
"No matter what a child's background, they should not be left behind in the current circumstances.
"We have got to fight for reinvestment in Scotland's youngest generation, because that is our future."
On the STUC's call to increase taxes, Mr Scott said: "Tax rises are inevitably going to happen for the top paid people in society because we Liberal Democrats want to close the tax loopholes at the very top that too many people have got away with for far too many years.
"So, on that, I agree with the STUC agenda.
"However, I don't think any hard-pressed lower or middle income families need to see tax rises."
