The setting of a national minimum of £100 for the grant has been welcomed by child poverty groups
Families are set to receive an increase in support for purchasing school uniforms.
A £100 minimum has been set by the Scottish Government for the school clothing grant, starting from next term.
Around 120,000 families are set to benefit from the fund – with the £12 million bill for the scheme being split between the government and local councils.
Previously, some councils such as Angus and North Ayrshire provided less than £50 for the grant, despite the average school uniform cost in Scotland standing at around £130 per year.
Education secretary John Swinney said the amount would be reviewed every two years to ensure it provides vital support to families.
"Every child in Scotland should be able to attend school feeling comfortable, confident and ready to learn,” he said.
"We know that school uniforms can be a considerable cost for families which is why we have worked in partnership with Cosla to introduce a new national minimum school clothing grant.
"It will help relieve pressure on families, reduce costs of living and remove the stress and stigma which can often be associated with struggling to afford essential school items."
John Dickie, director of the Child Poverty Action Group (CPAG) in Scotland, said: "£100 is now the absolute minimum grant that must be offered to families struggling on low incomes.
"Grants are already higher in some areas, and the actual cost of kitting out a child for school was recently calculated as £129.50.
"But this new £100 minimum provides a very welcome basic level of consistent support for parents, wherever they live in Scotland."
