Some 92.5% were offered their first choice, up from 92.2% in 2022-23 and the highest figure since 2014-15.
However, there was also a record low number of applications, with just 568,560 children fighting for the school places.
In East Sussex, 4,538 of 4,875 children (93.1%) secured a place at their first preference.
Schools minister Nick Gibb said: "It is great to know that up and down the country families are able to make the right choice for their child, enrolling them in a school and environment that they feel will best support their child to learn and develop.
"Today’s figures attest to the Government’s priority in providing good quality school places, which will ensure every child has the opportunity to meet their potential."
Here are the primary schools in East Sussex which were hardest to get into, based on Department for Education figures showing the proportion of families putting it as their first choice who were successful in getting a place.
