Plans are progressing to create additional school places at Wollaston Community Primary School to cope with demand.
Northamptonshire County Council is looking to increase the number of pupil places from 315 to 420 pupils to enable more children to attend their local school.
Cllr Matthew Golby, cabinet member for families and education, has approved a decision to publish a statutory notice to expand the school.
He said: “Wollaston Community Primary is a popular school and is currently full or over capacity in every year group, except year six.
“As part of our work to provide additional school places across Northamptonshire to cope with demand, we are creating these additional places at Wollaston Community Primary School to provide capacity for local families to attend their local school.”
The expansion will see an increase from 45 to 60 places per year group from September 2018.
There will be a two-storey extension to the school building to provide three new classrooms for the additional children, plus an outdoor covered play area, subject to separate consultation associated with the planning process.
The publication of the statutory notice marks the start of a four-week consultation period. The proposed expansion will then come back to cabinet for further discussion in September.
