Parents are fuming over 'out of control' school rules which see toilets locked and teachers changing the kids shoes.
Abbeyfield School, in Northampton, has faced criticism from parents after unveiling the rules before the start of the new academic year.
The rules now include a complete ban on trainers and - anyone who is found wearing them - will be forced to switch to a pair of 'smart shoes' given to them by the school.
One parent, who wished to remain anonymous, believed the rules are "not normal" and claimed the school is "completely out of control".
The parent told Northampton Chronicle : "The school has invested money in shoes, so when children arrive at the school gates and the teachers don’t like their shoes, they will be given ‘school approved’ shoes. This is NOT normal."
In addition, the parent said the school does not provide kids with lockers - even though there are empty lockers throughout the school.
According to the parent, toilets are locked and the kids are not allowed to use them during class time, which is "not normal".
The school children also have lunch at the same time which, according to the parent, sees a thousand kids in the lunch hall at one time - leading to long queues.
The parent said: "It’s a whole bunch of unreasonable demands which make this sound like an actual prison as opposed to a school, which educates and protects children.
"The system is completely out of control."
Abbeyfield School said the rules returning were in place before the pandemic.
A school spokesman said: "Abbeyfield school remains committed to achieving the highest standards of learning, behaviour and pastoral care.
"After adaptations to expectations during Covid disruption, the school has now reverted to its existing uniform policy that has been in place since its original launch in 2014.
"There have been no changes to the expectations in this regard, and trainers are specified as not being permitted.
"This remains the policy linked to the home school agreement that all parents have signed.
"Spare uniform stocks have been purchased so that any students who are in need of uniform can access these without issue or sanction and free of charge.
"We have also extended this to include accommodating students who arrive in incorrect items - this way alleviating parent need to purchase replacements in September.
"The principal and senior leadership team have organised opportunities for parent voice over the coming term.
"As always, we value parent input and welcome the opportunity to work with them."
