Inspectors have found improvements at a March school which was placed in special measures last year.
Maple Grove Infant School was found to be making progress but inconsistences remain in Year 1 teaching, according to Ofsted inspectors.
The school was placed in special measures after it was rated inadequate during an inspection in September last year.
Cambridgeshire County Council is looking at a proposal to merge the school with nearby Westwood Junior School and a decision will be made in the coming weeks.
Inspector Philip Mann completed a monitoring visit in February. The proposal is being considered as a result of the first Ofsted report.
He found school leaders were appropriately tackling the actions identified in the action plan with precise targets to accurately measure improvements in pupil achievement.
He states in a letter to headteacher Theresa Luter: “The observations I undertook with you during the monitoring visit indicate inconsistencies in teaching remain in Key Stage 1. However, examples of good teaching are evident in both Year 1 and Year 2. They form a model for further improvements across these year groups.
“Reviews by local authority advisers confirm that improvements continue to be made in provision within the reception class.”
Mr Mann also states that the middle level leadership team have received extra support and there has been specific training in the teaching of phonics and maths.
But he added: “The result of this support is yet to be reflected in better pupil achievement in literacy and numeracy.”
The county has been running a consultation with parents which ended on Friday.
Members of the county council’s children and young people’s committee will decide on the proposal to merge the two schools at a meeting next Tuesday, March 10.
If councillors agree a statutory notice will be published, with representations accepted between March 12 and April 8. The county is looking to make a final decision on April 16.
The new Westwood Primary School would continue to operate on both the existing sites from September, if the proposal is approved.
It could offer 90 places per year group, or a total of 630, and would provide 840 places by 2022.
Maple Grove has 265 pupils, aged from four to seven.
