Play England, Youth Sport Trust, and Opal with Bristol charity Children’s Scrapstore are signing up to the campaign.
Paula Phillips, head teacher of East Wichel Primary School in Swindon, said the school made the decision to change to an active uniform a few years ago.
“Coming out of Covid, we were seeing more and more children struggling with their mental health, spending more time on screens, and being less active than before [so] as a school, we knew we had to do something that would make a real difference,” she explained.
She said they believe physical and mental health go hand-in-hand and children have a “right to move, play, and spend time outdoors every day”.
