Plans have been unveiled to create around 3,800 new Surrey school places in the next academic year.
That is the equivalent of building around nine brand new two-form entry primary schools.
Surrey County Council aims to expand 20 schools in time for the return from the 2015 summer holiday.
It came as the council’s Cabinet signed off proposals to build 630 extra places at Stamford Green Primary, West Byfleet Infant and Junior and Ashford Park Primary School with 210 provided at each.
The expansion work forms part of the biggest investment project in Surrey’s history in response to growing demand fuelled by a rising birth rate.
It will see almost £330 million invested in providing the 20,000 extra places needed by 2019. Of those, 6,600 have been created during this academic year and the last one.
Surrey County Council’s Cabinet Member for Schools and Learning Linda Kemeny said: “We’ve experienced a huge increase in demand for places at our high-quality schools and this surge is continuing.
“That is why we embarked on the biggest school expansion programme Surrey’s ever seen with nearly £330 million being invested.
“By next September, extra classroom places will have been created for 10,400 schoolchildren in just three academic years and we’ll continue to make plans for the rest to ensure every child gets the best possible start in life.”
