Directed at the frontline and starting with the largest class sizes, it will target classes where teaching and learning needs to improve and where there are high levels of deprivation.
The money, consisting of both revenue and capital funding, will be invested over the next four years up until 2021.
The latest figures show that 7.6% (8,196) of infant pupils in Wales were in classes of over 30.
Kirsty Williams said:
“Our national mission is to raise standards and extend opportunities for all our young people.
“Time and time again parents and teachers tell me that they are concerned about class sizes. We have listened to these concerns, looked at the international evidence, and are today announcing a new £36m fund to address infant class sizes.
“There is a positive connection between smaller classes and attainment, particularly for pupils from poorer backgrounds. This is most significant for younger children, which is why we are targeting this investment at infant class sizes.
“This announcement, linked to our other reforms, will create the space for teachers to teach and for pupils to learn.”
