Risk assessments are being carried out ahead of more them reopening from Monday.
94% of schools in Oxfordshire have stayed open for children of key workers during the lockdown, and now the Government says the rest can open their doors again from June 1st.
151,000 surgical masks, 181,000 aprons, 121,000 gloves and 900 visors have been delivered by the council this week along with 7,500 litres of hand sanitiser.
The PPE is to help local schools provide an immediate response to if a pupil becomes unwell, which the authority says will be 'unlikely.'
Oxfordshire County Council says children will be taught in classrooms where safety, hygiene and social distancing are 'absolute priorities.
Meanwhile, schools are being asked to complete a risk assessment which will determine how many children can attend.
Ansaf Azhar, Director of Public Health at the council, said: "Whilst current scientific evidence shows little COVID transmission among children, we will never be complacent. The health of children, teachers, support staff, and parents will always come first in Oxfordshire.
"That is why all schools are now carrying out risk assessments to decide what provisions they need to put in place, and how many pupils they can teach whilst ensuring safety and social distancing.
"Safety, hygiene and social distancing are absolute priorities. And where community testing indicates clusters of COVID-19 - schools will close."
Councillor Lorraine Lindsay-Gale, Cabinet Member for Education and Cultural Services in Oxfordshire, said: "The health and safety of pupils, teachers and support staff is our number one priority.
"The teaching teams are incredibly dedicated. They have tirelessly provided education and assistance to pupils throughout the county, often through online learning, over these past few months.
"We will continue to support them by ensuring schools are safe, with the necessary social distancing and sanitation provisions in place, as increasing numbers of pupils come out of lockdown and return to the classroom."
Everyone over the age of five can access them if they have COVID-19 symptoms.
