Income Support and student couples with children claiming in long summer holidays?

Hi
Just back off MAT leave only to discover we are mid office move so can’t access any of my handbooks to check this and most my rights sites have been blocked on my computer - happy days!!!!!!!!
I am just updating student literature and cannot access up to date information as to whether or not student couples with children can still claim IS in long summer holidays - is this still the case or has it changed to JSA (IB)? Can anyone please clarify?
thanks Carrie
