Dame Alice Owen's Catchment (Priority) Area Guide 2027

Does Dame Alice Owen's School Have a Catchment Area?

Dame Alice Owen's School in Potters Bar is a co-educational secondary whose catchment area, which it calls Local Priority Areas, is a fixed list, not a radius. The list covers 15 Hertfordshire parishes and towns, nine Barnet and Enfield postcode districts and all of Islington, which is guaranteed at least 20 places. Only children living in these areas, or educated in Islington, were eligible for the 2027-entry academic and music tests; registration closed on 10 June 2026.

Unlike a straight-line radius, Dame Alice Owen's Local Priority Areas are not a distance rule at all. They are a fixed list: named parishes and towns within Hertfordshire, specific postcode districts within the London Boroughs of Barnet and Enfield, and — as a separate, guaranteed category — the whole of the London Borough of Islington. An address either appears on this list or it does not. The current version of this list, confirmed directly from the school's own Determined Admissions Arrangements for 2027-28 (correct as at February 2026), governs entry for September 2027. This page covers that geography only; for the entrance examination format, results and the full oversubscription order, see our Dame Alice Owen's School 11+ Complete Guide.

Dame Alice Owen's Catchment Area: Full List of Local Priority Areas for 2027 Entry

The school's Published Admission Number (PAN) for Year 7 is 200 children. Of these, only two of the seven oversubscription criteria — musical aptitude and academic ability — require a child to live in a Local Priority Area or be educated in Islington. The Local Priority Areas are set out below exactly as published in the school's Determined Admissions Arrangements for 2027-28.

That is 15 named Hertfordshire parishes and towns, plus nine postcode districts across the London Boroughs of Barnet and Enfield (note that some postcodes are only partially included — EN2 sectors 7 and 8 specifically, N11 sectors 1 and 3, N13 sectors 4 and 5 — while EN4, EN5, N12, N14, N20 and N21 are included in full). Islington sits apart from this list as its own guaranteed category, covering all Islington postcode sectors and, unusually, any child educated within the borough even if they do not live there. The school is explicit that these written definitions are the only definitive version: "Maps providing an overview of the Local Priority Areas [are] available to view on the school website… these maps are for indication purposes only — the definitive areas are those set out above."

Why Do Islington Families Get a Guaranteed 20 Places Every Year?

This is the single most distinctive feature of Dame Alice Owen's admissions, and it exists for a genuinely historical reason rather than a modern policy choice. Dame Alice Owen founded her original school in 1613 for boys from Islington, entrusting its administration to the Worshipful Company of Brewers, which remains the school's Trustee to this day. A girls' school followed in Islington in 1886 and merged with the boys' school in 1973; the transfer of pupils to the current Potters Bar site was completed in July 1976. Roads near the original site still carry the names Owen Street, Owen's Row and Owen Fields.

That Islington heritage is written directly into the current admissions policy. Regardless of how many Hertfordshire, Barnet or Enfield children apply for the academic and musical aptitude routes in any given year, the school's arrangements guarantee that at least 20 places are offered to children who either live in, or are being educated in, the London Borough of Islington. The school maintains two separate ranked lists for this purpose — one for Islington applicants and one for every other Local Priority Area — specifically "to ensure that at least 20 places are allocated" to Islington children each year. Those 20 places sit inside the published admission number of 200; they are not additional places.

Which of the Seven Admissions Criteria Actually Require Priority Area Residence?

The school runs seven separate oversubscription criteria in strict priority order, and the Local Priority Area rule applies to only two of them. Understanding which is which changes how a family should read their own chances.

Criteria that DO require Local Priority Area or Islington status:

Criterion 4 — Musical Aptitude (up to 10 places): Open only to children whose permanent home address is within a Local Priority Area, or who are educated in Islington, at both the closing date for test registration and the date of application. Candidates sit a written aural test first — children scoring below 50 marks do not progress — followed by an individual assessment, with places offered in rank order of combined marks.

Criterion 5 — Academic Ability (up to 65 places): The same residence-or-education requirement applies. Of the up to 65 places available under this criterion, the school first admits as many Islington children as needed to reach its guaranteed minimum of 20, then fills the remainder from the non-Islington Local Priority Areas.

Criteria that do NOT require Local Priority Area or Islington status:

Criterion 1 — Looked-after and previously looked-after children: No geographic restriction.

Criterion 2 — Locality (22 places): The 22 places closest to the school by straight-line distance, open to any address regardless of the Local Priority Area list — see the next section.

Criterion 3 — Siblings: No geographic restriction, provided the sibling definition and same-address rules are met.

Criterion 6 — Children of staff: No geographic restriction.

Criterion 7 — Locality (remaining places): Any places left after criteria 1-6 go to the closest remaining addresses, again with no Local Priority Area restriction.

How the "Locality" Places (Criteria 2 and 7) Differ From the Priority Area

Because these two mechanisms sit side by side in the same admissions policy, they are easy to conflate — but they work in opposite ways. The Local Priority Area list restricts eligibility for criteria 4 and 5 to a fixed set of named parishes, postcodes and Islington. The "Locality" places under criteria 2 and 7, by contrast, are open to literally any address and are decided purely by straight-line closeness to the school gates — there is no list to check against, only a distance to measure.

In practice this means a family living just outside every Local Priority Area boundary — for example in a Hertfordshire village not on the 15-parish list, or in a Barnet postcode sector not named in the school's tables — is not automatically shut out. If their address happens to be close enough to the school in raw distance terms, they can still be considered under criterion 2 (22 places) or criterion 7 (remaining places after the higher criteria are filled), entirely independently of the Priority Area list. The school's allocation reports show how narrow this route is, and that the distance changes from year to year: the furthest home-school distance offered under criteria 2 and 7 was 337.90 metres for September 2026 entry (report dated 2 March 2026) and 723.62 metres for September 2025 entry (report dated 5 March 2025).

How Many Children Reach Part Two of the Entrance Examination?

For families who do qualify for the academic route (criterion 5), the process runs in two stages. For 2027 entry, Part One, the Verbal Reasoning test, was timetabled for 1 September 2026, with an additional date of 2 September 2026 only if required. Results are age-standardised and ranked, and children ranked below position 325 are not invited to sit Part Two — this is a rank cut-off, not a fixed pass mark. After Part Two the school emails parents a breakdown of marks, the candidate's ranked position and the lowest ranked position offered in recent years. If a tie-break is needed for the 325th ranked position itself, it is resolved by straight-line distance to the school.

The 325 children who clear that cut sit Part Two — English and Mathematics — which for 2027 entry was timetabled for 26 September 2026. Their combined score across all three papers determines final rank order, with places offered from position 1 downward until the up to 65 available places (split between the Islington guarantee and the non-Islington Local Priority Areas) are filled. Where two or more children finish with identical combined marks, Verbal Reasoning takes precedence over English, which takes precedence over Mathematics, as the tie-break order.

For 2027 entry, test registration for both the Governors' Entrance Examination and the Musical Aptitude test opened at 10:00am on 29 April 2026 and closed at 4:00pm on 10 June 2026, and the school states plainly that it "is unable to consider registration requests received after this deadline." The Common Application Form to the home local authority is due separately, by 31 October 2026.

How Do You Check If Your Address Qualifies?

Distances for Dame Alice Owen's applicants are provided to the school by Hertfordshire County Council (HCC) and measured by computerised mapping, to two decimal places, along a straight line from the AddressBase Premium address point of the home to the address point of the school. This is the same methodology used for locality tie-breaks and for resolving the position-325 boundary case described above.

Families should not rely on postcode lookup tools, neighbours' experiences, or previous years' assumptions, because the Local Priority Area list is a fixed set of named parishes and postcode sectors rather than a radius — an address a few streets away from a qualifying postcode sector may fall entirely outside it. The school's admissions team and the published Determined Admissions Arrangements 2027-28 document (correct as at February 2026) are the only reliable sources. The school's own advice is to contact its Admissions Department if you are unsure whether an address falls inside or outside a Local Priority Area, because its maps are an overview that is "not detailed enough to identify specific road boundaries". The school also applies an address-integrity rule: if a family has changed address within the 36 months before applying, but has kept a previous home address less than 50 miles from the school, an application from the new, closer address will be treated as a temporary address for locality purposes, and the Governors refuse a place under criteria 2 and 7 where they consider the stated address to be a temporary one.

Applying From Outside the Catchment (Priority) Area

A family outside every Local Priority Area, and not educated in Islington, cannot register for the Governors' Entrance Examination or the Musical Aptitude test — those two routes are gated entirely on residence or education location. The routes still open to such families are the criteria with no area requirement: looked-after children (criterion 1), locality (criteria 2 and 7, decided on straight-line distance to the school), siblings (criterion 3) and children of staff (criterion 6), where they apply.

For September 2026 entry, the school's allocation report dated 2 March 2026 shows 1,109 children registered for the academic test, for which 65 places were allocated. The school's own admissions FAQ says an application from outside the Local Priority Areas is "extremely unlikely" to succeed under the locality criteria. Families whose address sits just outside a named parish or postcode sector should check the published list carefully rather than assuming from a nearby area, since the arrangements warn that the information may change for subsequent academic years.

Dame Alice Owen's Priority Area vs Other North London and Hertfordshire Grammar Schools

Dame Alice Owen's states that it is not part of the South West Herts Consortium and that its tests are unique to the school, so a family comparing north London and Hertfordshire grammar schools needs each school's rules read separately.

Dame Alice Owen's vs Queen Elizabeth's School Barnet: Queen Elizabeth's School publishes a separate admissions guide for September 2027 entry and for September 2026 entry, and asks parents to refer to the document for the correct year — see our QE Boys Barnet 11+ guide for the detail.

Dame Alice Owen's vs Watford Grammar School for Boys: Watford Grammar School for Boys offers 56 places (25% of total admissions) each year for boys who are selected by academic ability. That selection is managed through the South West Herts Schools Consortium, so boys must sit the Consortium academic test to be considered under that criterion, and for its specialist criteria the school divides its admission area into the Watford area and the rest of the admission area. Our Watford Grammar Schools guide covers the Watford schools.

Dame Alice Owen's vs Henrietta Barnett School: Henrietta Barnett is a non-denominational grammar school for girls, so Dame Alice Owen's, which admits boys and girls, is a live option for families where Henrietta Barnett is not. Our Henrietta Barnett designated area guide covers that school's geography.

For the fundamentals of Dame Alice Owen's admissions beyond geography — the full oversubscription order, the sibling and staff routes, and results-day guidance — see our Dame Alice Owen's School 11+ Complete Guide and our main Dame Alice Owen's School profile, and for a wider view of grammar school options across the county, see our Hertfordshire 11+ borough guide.

Getting to Potters Bar: Transport for Priority Area Families

Transport is a practical factor to weigh before applying, because the Local Priority Areas run from Islington and the Barnet and Enfield postcodes to Welwyn Garden City and Hatfield in Hertfordshire. The school's School Travel page lists five bus routes that serve Dame Alice Owen's: the 242 (Cuffley to Potters Bar), the 626 (Finchley, Whetstone, New Barnet and Potters Bar), the 699 (Winchmore Hill and Southgate to Potters Bar), the 313 (Ponders End, Enfield and Potters Bar) and the 610 (Hatfield, Welham Green, Brookmans Park and Potters Bar). The school says the buses arrive in time for the start of school and pick up after school at 3.40pm, although it marks routes 242 and 313 as "Scheduled Service – cannot vary times".

The same page links to Transport for London for bus timetables and to Great Northern for train timetables to Potters Bar, and notes that those sites are outside the school's control. Families should trial the journey at school-run times before committing to an application, and check the school's School Travel page for the current list of routes.
