School Catchment Property Premium: Top 1km School Effect

Updated May 2026 | PSF Insight

Walk through any Bukit Timah viewing in November and you will see the same scene: a young family pacing the unit with a phone open to OneMap, measuring the straight-line distance to Nanyang Primary. The 1km rule is not a marketing gimmick. It is a real MOE allocation mechanic that quietly underwrites a measurable PSF premium across districts 10, 11, 15, and a few specific HDB estates. This guide explains how the rule works, which schools matter, and how much the premium typically costs.

The 1km Rule: How MOE Phase 2A and 2B Work

For Primary 1 registration, MOE uses a phased system. After alumni and sibling priority, the next two phases are catchment based:

• Phase 2A: priority for children with parent connections (alumni, school staff, parent-volunteer status, advisory committee)
• Phase 2B: priority for children whose parents have volunteered 40 hours, are members of a related church or clan, or are active community leaders
• Phase 2C: open to all, with priority given by distance: within 1km, then 1km to 2km, then beyond 2km

For oversubscribed schools, Phase 2C is where the 1km rule bites. Living within 1km is often the difference between getting in and being balloted out. The address must also be the registered residential address for at least 30 months from the date of P1 registration if you used distance priority, otherwise the school can withdraw the place.

The Top Tier Schools That Move PSF

Not every primary school creates a property premium. The premium concentrates on roughly 15 to 20 oversubscribed names that consistently see Phase 2C ballot:

• Nanyang Primary (King's Road, district 10)
• Henry Park Primary (Holland Grove, district 10)
• Raffles Girls' Primary (Hillcrest Road, district 11)
• ACS Primary (Barker Road, district 11)
• Methodist Girls' Primary (Blackmore Drive, district 21)
• Tao Nan School (Marine Parade, district 15)
• Rosyth School (Serangoon, district 19)
• St Hilda's Primary (Tampines, district 18)
• CHIJ St Nicholas Girls' (Ang Mo Kio, district 20)
• Catholic High Primary (Bishan, district 20)
• Pei Hwa Presbyterian (Bukit Timah, district 21)
• Anglo-Chinese School (Junior) (Winstedt Road, district 9)

The premium attaches to the address, not the school list. A condo 950m from Nanyang Primary commands a different number than the same product at 1.1km, even on the same road.

How Big Is the Premium?

From transaction patterns in the last five years, the school catchment effect on PSF typically falls between 5% and 15%, with the higher end concentrated in three situations:

• Within 1km of a top-five name (Nanyang, Henry Park, RGPS, ACS, Tao Nan)
• Family-sized units (3-bed and above) where the buyer pool is overwhelmingly P1 parents
• Older leasehold or mid-range freehold projects where the school is the primary draw

The premium narrows for 1-bed and 2-bed units, since young families rarely buy them, and for ultra-prime addresses where lifestyle and prestige already dominate the price.

District 10 Example: Bukit Timah and Holland

Within the 1km zone of Nanyang Primary, mid-tier freehold condos around King's Road and Coronation Road typically transact 8% to 12% above similar specification freehold projects in district 21 outside any top school zone. The same effect applies around Henry Park Primary along Holland Grove and Holland Road, where the catchment overlaps with the Methodist Girls' zone for an unusual double-school address.

District 11 Example: Newton and Bukit Timah Fringe

Around Raffles Girls' Primary on Hillcrest Road, the 1km radius covers parts of Dunearn, Watten, and Bukit Timah Road. Family-sized 3-bed and 4-bed units within this radius trade at a 5% to 10% PSF premium versus similar units along Newton Road or Thomson Road just outside the radius. ACS Primary on Barker Road overlaps significantly, which adds a layer of optionality buyers will pay for.

District 15 Example: East Coast and Tao Nan

Along Marine Parade Road and Mountbatten Road, units within 1km of Tao Nan School consistently outperform comparable Marine Parade stock outside the catchment by roughly 6% to 10%. The premium is amplified when the project is also within 1km of CHIJ Katong Primary or Kong Hwa, allowing parents to hedge their school choice.

Practical Rules for Buyers

1. Verify the distance using OneMap, not Google Maps. MOE uses OneMap for distance, measured as a straight line from the home to the school gate
2. Confirm the gate that MOE measures from. Some schools have multiple gates and only one is the official reference point
3. Buy with a buffer. 850m is safer than 990m. Future development can shift access points marginally
4. Check your child's age window. The 30-month residency clock starts at P1 registration, not at unit handover. New launches with TOP after the registration year do not help
5. Do not pay top-school premium for non-top schools. If the catchment is for a school that never balloted in Phase 2C, the premium is largely behavioural and should be discounted

The Risk of Paying for a School Premium

School catchment premiums are real but conditional. Three risks reduce the resale value of the premium:

• School relocation. Henry Park is staying put, but boundary or campus moves can erase a premium overnight
• MOE rule changes. Discussions around removing distance priority surface periodically. A reform that weights ballots differently could compress the premium
• Demographic shifts. Districts with falling young-family populations see premiums fade as the buyer pool thins

The right way to think about a school premium is as 3 to 6 years of compressed value. If your child enters P1 in 2028 and you sell after PSLE in 2034, you are paying today's premium and recovering it from the next P1 cohort's parents. As long as you buy something else the resale market wants (good layout, decent age, sensible PSF for the district), the school premium pays for itself across one cycle.
