Secondary School Banding Estimator (How Band 1/2/3 Works)

This page explains how the Education Bureau cuts allocation bands, why no website can compute an exact Band, and what the estimator above actually does. It only places the child inside their own school, using the rank and historical shares you type. It is not the Bureau’s cut.

What an allocation band is

The Bureau bands students, not schools. “Band 1 school” is folk usage for a secondary school whose intake is mostly Band 1 students. It is not an official label.

Standardised, school-adjusted scores are ranked and split into three equal groups, each one third of the participating students. The territory band is used for Central Allocation Part A (choices not limited by school net). The school-net band is cut again inside each of the 18 secondary-school nets and is used for Part B (choices inside the net). A student’s net is, in principle, the administrative district of their primary school.

Individual bands are never released to parents. Bands are computed only when the allocation programme runs, after the final participant counts are fixed.

How the Bureau arrives at a band

Primary schools mark on different scales, so the same raw mark is not automatically comparable across schools. The computer first standardises each student’s first, second and third internal-assessment submissions so those marks can be compared.

It then adjusts them by the average of the school’s two most recent Pre-Secondary One Hong Kong Attainment Test (Pre-S1 HKAT) samples. For the 2025/2027 cycle (Primary 6 in 2026/27, Secondary 1 in September 2027) those samples are 2024 and 2026. The previous cycle (2024/2026) used 2018 and 2024.

The Pre-S1 HKAT does not directly affect the sitting student’s own allocation. The Bureau says schools and parents need not drill for it. The date for the 2025/2027 cycle is 13 July 2027. Bands exist only when the allocation programme runs; there is no personal band on file beforehand that a parent can look up.

Why no website can compute an exact Band

The Bureau’s 2025/2027 briefing states it plainly: using past cohort profiles plus a student’s internal marks or rank, a school cannot precisely predict an individual’s band. The actual band may differ from what the school or the parents expected.

What is missing is not a hidden formula but three facts only the Bureau holds. First, other schools’ distributions that year: standardisation is territory-wide and net-wide, not within one primary. Second, this year’s final participant counts: the three equal thirds are cut only after those counts are fixed. Third, the size of the school adjustment: each school’s HKAT sample averages are not public.

The estimator above does one job. It takes the rank and year-group size you enter, reports the child’s place inside that school (top x% of the year group), and reads an indicative band from the Band 1 and Band 2 shares you type (equal thirds until you change them). It cannot see other schools, this year’s headcount, or the adjustment. It cannot compute the real band.

A worked example

The split figures below are illustrative inputs, not data from any school. Suppose the child is 40th of 120. The estimator divides rank by year-group size: 40÷120 = 33.3%, shown as the top 33.3% of the year group.

Under the default equal thirds, 40th sits on the lower edge of Band 1, so the indicative reading is Band 1. If a parent opens the advanced fields and types a past split of about 20% Band 1 and 40% Band 2, the same 33.3% is past the 20% Band 1 line and the reading becomes Band 2. At another school typed as 45% / 30%, the same rank still reads as Band 1.

Same rank, different school split, different estimate. That is why the school context dominates: the tool reads the shares you enter for that school, not a hidden territory-wide cut. You supply the shares. This site does not hold official figures for any school.

What cross-net allocation does to the band

A student approved for cross-net allocation joins Part B in the new net. The school-net band is decided again by comparing their adjusted marks with students in that new net. The territory band does not change. Part A still uses the original territory band.

Approval also ends eligibility for reserved places at the original primary’s feeder or nominated secondary. If the family is counting on that reservation, that loss matters as much as the band itself.

Feeder and nominated reserved places, and the band

After repeaters and Discretionary Places, a feeder secondary reserves 85% of the remainder for its feeder primary; a nominated secondary reserves 25% for its nominated primary. Eligible students are those in net Band 1 or 2 who put that school as their first choice in Part B. If the reserved places are over-subscribed, the computer uses net band and then the random number. Unused reserved places go into open allocation.

The band has a concrete job here: only net Band 1 and 2 meet the eligibility threshold. A Band 3 student who lists the school first in Part B is outside this reserved-place arrangement.

Common misunderstandings

• “Band 1 school” is an official category.The Bureau bands students. Secondary schools have no official band label. The phrase is folk usage for an intake pattern.
• A strong primary must mean a worse band.The school adjustment reflects how recent graduates did on the HKAT. Competition inside a strong year group is tougher, so a mid-pack rank may sit lower in the territory or the net than a parent expects, while the adjustment also credits the school’s overall standard. The two effects pull opposite ways. No website can compute the result.
• A Discretionary Places offer reveals the band.Discretionary Places use each school’s published criteria, not allocation bands. Being notified as successful, wait-listed or not notified does not work backwards into a band. Bands are used later, at Central Allocation.
• The Pre-S1 HKAT is an entrance exam.It adjusts the school’s internal scores for later cohorts so marks from different primaries can be compared. It does not directly decide the sitting student’s own place. For the 2025/2027 cycle the date is 13 July 2027.
• This site’s estimate is official.It is not. The tool only places the child inside their own school, using the historical shares you type. The Bureau sets the real band from standardised, school-adjusted scores across the territory and the net.
