Kambala came in at 12th, followed by the Conservatorium High School.
Willoughby Girls High was the highest-placed public comprehensive school at 55th, while Newtown High School of Performing Arts climbed more than 30 places to 56th, and Cheltenham Girls’ High ranked 57th.
Epping Boys High has leapt 20 places to become the fourth-placed non-selective public school at 60th after recording its best result on record, propelled by a success rate of almost 25 per cent.
St Clare’s College at Waverley was the top Catholic systemic school at 48th, just behind Barker College and ahead of Kincoppal-Rose Bay and several selective schools. Parramatta Marist High and Bridgidine Randwick rounded out the top three Catholic schools.
North Sydney Boys has maintained its hold on first place on the back of a major lift in English advanced scores over the past six years. The school sensationally took top place last year, ending James Ruse’s 27-year reign as number one.
However, the gap between the top two selective schools has narrowed from nine percentage points last year to just two this year as North Sydney Boys’ success rate fell to 64.9 per cent.
The Herald calculates its rankings using success rates, which are the ratio of band 6, or E4 results, marks of 90 and above compared to the number of students who sat exams.
North Sydney Boys’ success rate declined by five percentage points, while James Ruse improved by almost three percentage points.
Of the top 300 schools, 73 were public comprehensives, up from 67 last year, while 16 were partially selective and 20 were fully selective. Private schools took 131 places, and Catholic schools 60.
An analysis of the top 50 schools shows that 21 are single-sex private institutions, and seven are single-sex public schools. Nineteen all-girls schools ranked in the top 50 compared with 10 boys-only schools.
Some of the biggest improvers this year include Barrenjoey High, skyrocketing 223 spots and The Ponds High, which leapt by more than 100 places.
Pittwater House School jumped almost 50 places to 49th, its best result on record. Marist Catholic College North Shore, which became co-ed several years ago, climbed more than 40 places to 76th.
Overall, public schools’ success rate was up on average 1.9 percentage points and selective schools jumped about 1.5 points. Independent schools, which dominated Tuesday’s first-in-course awards, had an average of one-third of a point increase in their success rate.

The share of high marks needed to crack the number one spot has tumbled from 77 per cent in 2017 to 65 per cent this year, but the average success rate of the top 10 has stayed at about 55 per cent for the past decade.
The Herald’s analysis only includes schools where at least 150 HSC subject results have been registered. Band 6 and E4 results in different subjects are not equal.
Each band awarded represents what a student knows, understands and can do within each course. The average performance in most courses is usually a mark in the mid-70s or a band 4.
The NSW Education Standards Authority only provides band 6 results, although the Herald publishes a separate analysis on improvement based on schools’ average scores each year.
The data is not adjusted for socioeconomic advantage, and almost all of the top 150 schools have students who come from the most advantaged backgrounds.
