Thousands will find out which school their child has been offered a place at today.
More than 93 per cent of 7,125 children, who are due to start school this September, have been given a place at their preferred choice.
Oxfordshire County Council will inform families today of which schools prospective pupils have been allocated to.
This is an increase of around 1 per cent on 2018, and above the national average from the last few years.
The authority's director for children's service, Lucy Butler said: "Once again we're delighted to be able to offer the overwhelming majority of families their first preference school, and wish all the children the very best for the coming school years.
"We constantly monitor demand for places and work closely with all schools to ensure there is sufficient capacity both across the county as a whole and within local areas.
"Oxfordshire compares very favourably with other parts of the country on school places and our strong track record on first-preference offers is down to that effective forward planning.
"We aim to give every Oxfordshire child a good start in life and this is part of that work"
The council says since 2010, the number of primary school places in Oxfordshire has risen by 22 per cent.
An appeal process is available to families wishing to challenge the outcome of their application, and details of how to do this have been sent to parents.
Children's names can also be placed on 'continued interest' lists in case places become available at schools at a later date.
