Concerns that reports of bullying are not always followed up have seen a school's Ofsted rating downgraded.
Cliff Park Ormiston Academy in Gorleston has received a grading of "requires improvement" in its latest Ofsted inspection - a step down from its previous one, which was "good".
The seaside secondary was visited by inspectors last month, its first inspection since 2016.
And while the inspectors said new leadership at the school has "brought much-needed calm to behaviour in corridors and classrooms", some concerns were still raised.
The report reads: "Pupils have experienced an unsettled time. However, they say the new leadership has steadied and improved the school.
"The trust and leaders know there is a lot of work to do to improve the school. They identify that standards in the school declined during the pandemic."
The inspectors added they were concerned the teaching was not always consistent and that pupils with special educational needs do not always get the support they need.
The report adds: "Some staff do not follow up on pupils' concerns about behaviour as well as they should.
"This includes incidents of bullying and prejudicial language.
"This means that some pupils are not confident to report issues they may have so they can be resolved promptly and efficiently.
"Leaders should ensure that the curriculum and school ethos supports all pupils to respect diversity."
Harry French, principal at Cliff Park, said: "Although the outcome of the Ofsted inspection is disappointing, it has been a challenging couple of years for the academy and we are confident that we will now be able to make rapid and sustained improvements to ensure we are providing an excellent education for every student.
"We are proud of the strengths highlighted in the report and are already working hard to address the identified areas for further development swiftly.
"We now look forward to working closely with everyone across the academy community and the trust to continue to build on the progress we have already made."
While the inspectors did raise concerns, other areas were praised, including the way pupils engage in charity work to help prepare them for the wider world.
