The duty in one paragraph
Keeping children safe in education (KCSIE) 2026 says governing bodies and proprietors should do all they reasonably can to limit children’s exposure to online risks from the school’s IT system. They should make sure the school has appropriate filtering and monitoring systems and that a review of their effectiveness is carried out at least once every academic year (paragraph 173).
KCSIE 2026, in force since 1 September 2026, adds detail on how that review happens. It should be carried out by “the SLT member responsible for filtering and monitoring, with the support of the school’s designated safeguarding lead and IT support”. It should include checks that filtering is working on all internet-connected devices in all relevant locations, and “a record should be kept of these checks”.
What counts as “appropriate” is for each school to decide, informed partly by its Prevent duty risk assessment (paragraph 174). KCSIE also warns against “over blocking” that unreasonably restricts what children can be taught (paragraph 163).
Filtering and monitoring: the difference
The DfE’s filtering and monitoring standards define the two terms:
- Filtering is preventative. It blocks access to illegal, inappropriate and potentially harmful content, including AI-generated content.
- Monitoring is reactive. It shows what users are doing on devices and raises reports or alerts. It doesn’t block anything. Monitoring includes staff watching screens as they walk round a classroom, as well as software.
The standards also say that no filtering system is 100% effective, so staff supervision still matters.
The four standards
KCSIE paragraph 175 summarises the DfE’s standards. Schools should:
- identify and assign roles and responsibilities to manage filtering and monitoring systems
- review filtering and monitoring provision at least annually
- block harmful and inappropriate content without unreasonably affecting teaching and learning
- have effective monitoring strategies that meet their safeguarding needs
The standards page says schools “should already be meeting” all four.
Who does what
| Role | What the DfE standards give them |
|---|---|
| Governors or proprietor | Overall strategic responsibility. Name a senior leader and a governor responsible for meeting the standards. |
| Senior leadership team | Scope needs, including generative AI. Buy the systems, document what is blocked or allowed and why, review effectiveness and oversee reports. Make sure staff are trained and act on reports. |
| Designated safeguarding lead | Lead on safeguarding and online safety. Check reports, respond to safeguarding concerns that filtering and monitoring raise, and give governors assurance that the systems work and are reviewed. |
| IT support, in-house or contracted | Maintain the systems, provide reports and complete actions after concerns or checks. Help with buying, risk, reviews and checks. |
| All staff | Supervise pupils on devices, and report anything that gets through, is wrongly blocked or seems broken. |
KCSIE says the DSL’s lead responsibility includes “online safety and understanding the filtering and monitoring systems and processes in place”, and that this should be explicit in the job description (paragraph 127 and Annex B).
Filtering and monitoring isn’t only the IT provider’s job. KCSIE says all staff should get safeguarding training at induction that includes “an understanding of the expectations, applicable roles and responsibilities in relation to filtering and monitoring” (paragraphs 12 and 153), and online safety updates at least annually (paragraph 154).
Policies and parents
KCSIE says the school’s approach to online safety should be reflected in its child protection policy, which should include appropriate filtering and monitoring on school devices and school networks (paragraph 169). The DfE standards add that monitoring procedures should be reflected in the acceptable use policy and other relevant policies, such as privacy notices, and that pupils, staff, parents and carers should know about them.
KCSIE also suggests telling parents and carers what systems the school uses to filter and monitor online use (paragraph 172).
What the standards expect of the system
Neither KCSIE nor the DfE standards name approved products. KCSIE says what is appropriate is a matter for each school (paragraph 174), and the standards set requirements any system should meet. The main ones:
- The filtering provider should be a member of the Internet Watch Foundation (IWF), signed up to the Counter-Terrorism Internet Referral Unit (CTIRU) list, and update its blocklists from both. No one in the school or trust, including system administrators, should be able to disable or override those blocklists.
- Filtering should apply to school-managed devices, including those taken off site, unmanaged devices under a bring-your-own-device scheme, and guests using the school internet. Devices the school doesn’t manage should be on a separate network.
- There should be at least separate pupil and staff filtering profiles, not one blanket setting.
- Any temporary exception, such as for a system update, must be approved and documented by the senior leader responsible, and the DSL should assess the safeguarding implications.
For what “appropriate” filtering and monitoring means in practice, KCSIE points to the UK Safer Internet Centre’s guidance and SWGfL’s provider checking tool (paragraph 177).
The annual review: a checklist
The standards say the review should involve the senior leadership team, the DSL, IT support and the responsible governor. It should look at:
- the pupils’ risk profile, including age, special educational needs and English as an additional language
- what the filter currently blocks or allows
- how technology is used, including any bring-your-own-device policy
- where generative AI products are used in school
- technical limits, such as whether the system can handle real-time, dynamic, personalised or AI-generated content
- outside influences such as county lines, and any relevant safeguarding incidents
- what the curriculum needs, for example in RSHE and PSHE
- related policies, including how temporary exceptions are approved
- what checks happen now and how actions are followed up
Record the results and actions. The standards say the record should be available to anyone entitled to inspect it. Review again, between annual reviews, when a safeguarding risk is found, working practice changes, new devices or AI tools arrive, or there are major software or network changes.
Checks and the log
Checks are part of the review. How often they happen depends on the school’s risks. They should confirm that filtering covers school-owned devices (including those taken home), every site, and the right content for pupil, staff and guest accounts. Keep a log of when each check took place, who did it, what was tested and what action followed. The standards suggest using a testing tool, such as the one from SWGfL, to confirm that illegal child abuse content, terrorist content and adult content are blocked.
Monitoring reports
The standards say a monitoring plan should, as a minimum, include weekly reports highlighting incidents, and immediate reports for high-risk incidents. Pupils and staff should know monitoring is in place.
Generative AI
KCSIE 2026 widens its description of online risk. The “contact” risk now includes harmful interaction with “generative AI applications that simulate this”, and the “conduct” risk includes explicit images “generated using AI” (paragraph 165). It points schools to the DfE’s guidance on generative AI in education and its AI resources for staff (paragraphs 167 and 168).
The filtering and monitoring standards say schools should consider whether they need a system that can handle AI-generated content. Schools introducing a generative AI product should assess the risks against the DfE’s Generative AI: product safety standards. Those standards expect AI products to have filtering built in that holds for a whole conversation, to log prompts and responses, and to alert the DSL to possible safeguarding disclosures.
KCSIE also suggests the DfE’s “Plan technology for your school” service for self-assessing against the standards (paragraph 176).
