Education watchdogs have criticised Banff Primary School and Nursery for making “insufficient” progress since its last inspection.
In September 2017 Education Scotland inspectors assessed the north-east facility and ranked it weak in two areas, satisfactory in three and good in three.
Representatives from the body returned to the school recently to assess what improvements had been made, but concluded that there had not been enough advances.
Education Scotland has now sent a letter to parents advising that the school had “made insufficient progress since the original inspection”.
It stated: “We will liaise with Aberdeenshire Council regarding the school’s capacity to improve.
“We will return to carry out a further inspection within six months.”
The recent inspection found that curriculum improvements had been made but were “not yet being used consistently” across the school.
It also said that instability with staffing and significant staff changes have prevented consistency in teaching.
The report added: “We ask the education authority to take steps to provide the headteacher with two permanent depute headteachers to support the work of the school.
“There is a need to ensure that the vacancies within the school are filled.”
But the further inspection did find there are now clearer arrangements in place to monitor children’s learning progress, with staff more involved in tracking attainment.
