All girls in Rhondda Cynon Taf will have access to free sanitary products to tackle period poverty
Plans to give free sanitary products to all Rhondda Cynon Taf schools with pupils aged nine and above have been given the go-ahead.
A six-month trial will start this summer and it will be fully rolled out by April 2019.
The council cabinet's decision comes after a campaign led by Plaid Cymru and Rhondda Cynon Taf councillor Elyn Stephens to eradicate period poverty.
The Welsh Government had previously announced more than a million pounds worth of funding for tackling period poverty.
Councillors say period poverty can have an impact on pupils' education, with some missing school as a result.
It also a problem for women on low incomes, who may have to prioritise other products such as food.
