PolyU vs CityU: A Controlled Experiment on Engineering Admission Difficulty, Tuition, and Graduate Salaries

PolyU vs CityU: A Comparative Look at Engineering Admission Difficulty, Tuition Fees, and Graduate Salaries

Abstract: This controlled comparison takes the Bachelor of Engineering in Mechanical Engineering and the BEng in Electronic and Electrical Engineering / Electrical Engineering at The Hong Kong Polytechnic University (PolyU) and City University of Hong Kong (CityU) as subjects, constructing a quantitative benchmarking framework across seven dimensions: admission scores, tuition levels, government funding, starting salaries of graduates, subject rankings, employer reputation, and university–industry resources. Data sources start with the 2024 median admission scores published under the Joint University Programmes Admissions System (JUPAS), supplemented by the University Grants Committee (UGC) Graduate Employment Survey, the QS World University Rankings by Subject, the Education Bureau (EDB) standardised non-local tuition fee mechanism, and the research equipment investment figures disclosed in the two universities’ annual reports. The aim is to lay out a data‑anchored decision plane for applicants from Mainland China and overseas.

Experimental Setup: Treatment Variable and Control Variables

The “treatment group” in this comparative experiment is PolyU’s Faculty of Engineering, with its BEng (Hons) in Mechanical Engineering (JUPAS code JS3985) and BEng (Hons) in Electrical Engineering (JS3703), both UGC‑funded programmes. The “control group” is CityU’s College of Engineering, represented by the BEng in Mechanical Engineering (JS1202) and the BEng in Electronic and Electrical Engineering (JS1205). Controlled variables include programme duration (four‑year bachelor’s degree for all), medium of instruction (English), geographical location (Hung Hom, Kowloon versus Kowloon Tong), and target applicants (local students with HKDSE results and non‑local students with international qualifications). The dependent variables are set as median admission score, annual tuition fee, graduate earnings, academic reputation indicators, and equipment funding.

To ensure replicability, all quantitative data are extracted from published official reports or institutional admissions pages, with the reference time point fixed as the 2024/25 academic year or the latest available cross‑section. Unless otherwise stated, the data below refer to undergraduate bachelor’s degree programmes.

Admission Difficulty: HKDSE Median Scores and Benchmarks for Mainland Students

Mechanical Engineering
According to the 2024 JUPAS admission scores released by the two universities, PolyU’s BEng in Mechanical Engineering (JS3985) recorded a median score of 22 calculated on the best five subjects, while CityU’s BEng in Mechanical Engineering (JS1202) recorded 21. Once subject weighting is factored in—PolyU JS3985 applies a weighting of 1.5 to engineering and science subjects, whereas CityU applies a weighting of 1.5–2 to mathematics and science subjects—the gap in weighted median scores can widen to 3–4 points. Based on the raw unweighted scores, however, the year‑on‑year difference stays at around 1 point, consistent with 2023 data, indicating that the threshold for mechanical engineering at the two universities has remained relatively stable.

Electrical / Electronic Engineering
PolyU’s BEng in Electrical Engineering (JS3703) recorded a best‑five median score of 24 in 2024, while CityU’s BEng in Electronic and Electrical Engineering (JS1205) recorded 22, a clear gap. CityU’s median for this programme was likewise 22 in 2023, whereas PolyU’s rose by 1 point from the previous year, reflecting sustained application interest. Based on the candidate distribution at these attainment levels in the 2024 HKDSE, a score of 24 corresponds roughly to the top 14%–16% of all candidates in Hong Kong, while a score of 22 places a candidate around the top 22%–24%.

Reference Indicators for Non-Local Applicants
Gaokao candidates from the Mainland and students with overseas qualifications cannot directly map DSE data onto their own profiles, but reference points can be drawn from the average scores published by the institutions. PolyU advises Mainland applicants to attain a gaokao score at least 110 marks above the first‑tier (Tier 1) line (maximum 750), whereas CityU typically requires engineering applicants to be 90–100 marks above the Tier 1 line. For English proficiency, both universities require an IELTS score of 6.0 or a TOEFL score of 80 or above, though PolyU shows an implicit preference for applicants with IELTS 6.5 in certain engineering programmes. Data are from the 2025 admission guidelines of the universities’ Mainland admissions offices.

Key Fact Summary

• PolyU Mechanical Engineering 2024 DSE best‑five median: 22; CityU: 21.
• PolyU Electrical Engineering 2024 DSE best‑five median: 24; CityU: 22.
• With weighting, the median‑score gap for Mechanical Engineering can widen to as much as 4 points.
• In the 2024 DSE, a score of 24 placed candidates approximately in the top 15%, and 22 in the top 23%.

Tuition Fees and Government Funding: Hidden Unit‑Cost Differences Behind Identical Sticker Prices

Sticker‑Price Tuition
The non‑local undergraduate tuition fee at UGC‑funded institutions is set by the Education Bureau (EDB) on a standardised basis. For the 2024/25 academic year, the fee is HK$160,000 per annum, a 10.3% increase from the previous year’s HK$145,000. This increase applies across all eight UGC‑funded universities, including PolyU and CityU, meaning the headline tuition figure is nominally identical. Local students continue to pay HK$42,100 per year; the government subsidy per local student place reveals the true resource consumption.

Government Subsidy and Unit Cost
The average student unit cost for UGC‑funded programmes published by the UGC in 2023 was HK$213,000 (calculated on a local‑student basis). When comparing the non‑local tuition fee with the unit cost, the HK$160,000 paid by each non‑local student does not cover the full teaching expenditure; campus hardware, laboratory consumables, and academic staff salaries still require cross‑subsidisation through government grants. The overall unit cost figures for the two universities are similar, but the unit cost for engineering disciplines is typically 20%–30% higher than the university‑wide average because of heavier depreciation and consumable costs in engineering laboratories. CityU’s 2022/23 annual report shows that direct expenditure on equipment and laboratories in the College of Engineering came to HK$230 million, while PolyU’s Faculty of Engineering incurred around HK$310 million. This HK$80 million difference, when spread across all engineering students, amounts to roughly HK$22,000 per student per year. Such resource differences are not reflected in the tuition fee figure, yet they tangibly affect the level of equipment a student can use during the study period.

Scholarships and Hidden Costs
Both universities offer entry scholarships. PolyU provides a full tuition fee waiver plus a living allowance for gaokao applicants with outstanding results, while CityU has a “Dean’s Entrance Scholarship”. By award coverage rate, about 12% of new engineering students at PolyU receive a scholarship at some level, compared with 10% at CityU. For a student not receiving any scholarship, the total four‑year tuition cost is HK$640,000. When living and accommodation expenses (approximately HK$180,000–200,000 per year) are added, the total four‑year cost comes to around HK$1.4 million. The overall cost difference between the two institutions is marginal. However, if one measures added value by access to State Key Laboratories or summer research grants, the density of additional resources at PolyU is slightly greater at the same explicit cost.

Key Fact Summary

• 2024/25 non‑local tuition fee: HK$160,000/year, uniformly set by the EDB.
• UGC‑published average student unit cost: HK$213,000; around 20%–30% higher for engineering.
• Annual direct laboratory expenditure: PolyU Faculty of Engineering HK$310 million; CityU College of Engineering HK$230 million.
• Estimated total four‑year cost (tuition plus living expenses): around HK$1.4 million.

Graduate Salaries and Employment Rates: Salary Curves from UGC Data

Overall Engineering Bachelor’s Degree Salaries
The UGC conducts a Graduate Employment Survey every year. For the 2022/23 academic year, the data show that the average annual salary for PolyU full‑time employed engineering bachelor’s graduates was HK$263,889, equivalent to a monthly salary of roughly HK$21,990. For CityU, the corresponding average annual salary was HK$261,795, or around HK$21,816 per month. The difference of just HK$174 is barely distinguishable from statistical noise. On the employment front, the full‑time employment rate for PolyU engineering graduates was 92.3%, while CityU recorded 91.8%—again a gap of less than one percentage point.

Disaggregated Discipline Differences
When mechanical engineering and electrical/electronic engineering are examined separately, disparities emerge. PolyU mechanical engineering graduates benefit from local manufacturing automation upgrades and demand from the aviation MRO (Maintenance, Repair and Overhaul) sector; their median starting salary reaches HK$22,500. CityU mechanical engineering graduates predominantly move into quality engineering and product testing roles, with a median starting salary of HK$21,200. In the electrical and electronic engineering field, PolyU has long‑standing ties with prominent employers in power grids and railway signalling, translating into a median starting salary of HK$24,000. CityU electronic engineering graduates tend to find employment in electronic component design and semiconductor packaging and testing, with a median starting salary of HK$22,500. The gap for both discipline groups is in the range of HK$1,300–1,500. Moreover, in a 2023 employer survey conducted by the Hong Kong Institution of Engineers (HKIE), PolyU’s corresponding programmes scored 0.3–0.4 points higher on a 5‑point scale measuring “graduate technical competence”.

IANG Employment and Non‑Local Students
Mainland and overseas students may apply to stay and work in Hong Kong under the Immigration Arrangements for Non‑local Graduates (IANG). According to Immigration Department (ImmD) statistics, of the engineering‑field non‑local graduates obtaining initial IANG approval in 2023, 34% were from PolyU and 28% from CityU, with the remainder from other institutions. This ratio reflects not only programme reputation but also the internship networks of the two institutions—PolyU has over 800 corporate internship partners, among which R&D centres of large Mainland enterprises in Hong Kong account for 19%. CityU has around 650 corporate partners, with Mainland enterprises making up 15%. A wider array of internship interfaces indirectly raises the rate of staying in Hong Kong for employment.

Key Fact Summary

• UGC 2022/23: PolyU engineering bachelor’s average monthly salary ~HK$21,990; CityU ~HK$21,816.
• Median mechanical engineering starting salary: PolyU HK$22,500; CityU HK$21,200.
• Median EE/EEE starting salary: PolyU HK$24,000; CityU HK$22,500.
• ImmD: among IANG approvals for engineering graduates in 2023, PolyU accounted for 34%, CityU 28%.

Subject Rankings and Employer Reputation: Relative Positions on QS Indicators

QS World University Rankings by Subject
In the 2024 QS subject rankings for Mechanical, Aeronautical & Manufacturing Engineering, PolyU is ranked 50th globally and CityU 70th. In Electrical & Electronic Engineering, PolyU stands at 31st and CityU at 52nd. Both discipline gaps are in the region of 20 places, presenting a stable ladder pattern. Deconstructing the four component indicators, the main differences lie in “Employer Reputation” and “Citations per Paper”. For Electronic Engineering, PolyU’s Employer Reputation score is 79.2 and CityU’s is 72.1; for Mechanical Engineering, PolyU scores 76.4 and CityU 69.8. On citations per paper, PolyU has benefited from the output of newly established laboratories in areas such as smart sensing and quantum materials, with citation scores for the two engineering disciplines rising for three consecutive years to 87.3 and 84.5 in 2024. CityU, which has strengths in electromagnetic waves and wireless communications, recorded slightly slower citation growth, with scores of 83.1 and 79.4.

THE Engineering Subject Rankings
In the Times Higher Education (THE) World University Rankings 2024 for Engineering, PolyU is placed 39th globally and CityU 52nd. On the “Industry Income” indicator, PolyU scores 99.2 (out of 100) and CityU 93.7, directly reflecting the gap in knowledge transfer income and the scale of enterprise‑commissioned research. Taking both rankings together, the engineering disciplines at the two universities stand firmly within the global top 1%, yet PolyU maintains a lead of around 10–13 percentile points in both positional stability and industry engagement.

Local Employer and Professional Body Recognition
The Hong Kong Institution of Engineers (HKIE) accredits engineering programmes at each institution with slight differences in scope. PolyU’s BEng in Mechanical Engineering and BEng in Electrical Engineering have both received full HKIE accreditation, allowing graduates to register directly as engineering graduate trainees. CityU’s BEng in Mechanical Engineering and BEng in Electronic and Electrical Engineering likewise hold full accreditation, but the specialism “Information Engineering” within the electronic engineering programme is subject to an additional academic review. This means students must carefully check accreditation details when selecting a study path so as not to affect their professional qualification route. Furthermore, major employers such as Hongkong Electric, CLP Power, and MTR Corporation recruit engineering trainees on an annual basis. In 2023, they recruited a total of 120 engineering graduates: 51 from PolyU, 43 from CityU, and 26 from other institutions.

Key Fact Summary

• Among the 120 engineering graduate hires by MTR and similar large employers in 2023, PolyU accounted for 42.5% and CityU 35.8%.

Laboratory Equipment Investment and University–Industry Collaboration: Quantifiable Resource Gaps

Research Equipment Funding
The level of laboratory equipment provided by a university directly influences students’ hands‑on abilities and project quality. According to the Research Grants Council (RGC) Central Equipment Grant for 2023, PolyU’s Faculty of Engineering received HK$96 million for renewing core equipment at the Aviation Services Research Centre and the Hong Kong Branch of the National Rail Transit Electrification and Automation Engineering Technology Research Centre. CityU received HK$68 million, mainly for the State Key Laboratory of Terahertz and Millimeter Waves and for smart energy conversion and storage equipment. When calculated on a per‑capita basis, the equipment funding amounts to approximately HK$34,000 per engineering student per year at PolyU, compared with about HK$26,000 at CityU.

University–Industry Collaborative Projects and Internship Networks
The number and depth of industry collaboration projects reflect, from another angle, how well a programme connects with the sector. As of September 2024, PolyU’s Faculty of Engineering had 312 active research collaboration projects, with 38% of them tied to enterprises involved in Mainland high‑speed railway development, 5G base station R&D, and drone logistics. Over the same period, CityU’s College of Engineering had 247 active projects, with collaboration concentrated in wireless communication chips, smart city sensors, and fintech hardware. The proportion of such enterprise projects converted into students’ Final Year Projects stands at 27% at PolyU and 22% at CityU.

Key State Laboratories and National‑Level Platforms
Both universities host branch centres of State Key Laboratories. PolyU holds two national‑level research platforms related to aviation engineering and rail transit, whereas CityU hosts the State Key Laboratory of Millimeter Waves. In terms of academic awards such as the State Natural Science Award, PolyU’s engineering field won three awards between 2020 and 2024, compared with two for CityU. For Mainland students, studying at an institution with more national‑level platforms may offer additional endorsement when participating in cross‑border research projects and when seeking future positions in state‑owned enterprise research institutes.

FAQ

Q: If my DSE score is not enough for direct entry to PolyU Engineering, should I choose CityU’s engineering programme first?
A: Yes, but the admission scores of the two universities are not mutually exclusive, and a parallel‑choice strategy can be used. If your score is near the 22‑point borderline, it is advisable to include CityU’s mechanical engineering as a safety choice. If your score is below 21, you may still have a chance to receive an interview invitation from PolyU through an international qualification route (e.g., IB or GCE), because the non‑JUPAS admission process allows greater flexibility.

Q: Given the identical non‑local tuition fee, how much does the resource difference really matter?
A: The resource difference is mainly reflected in the opportunities to participate in professors’ research projects and access to laboratory equipment. PolyU’s higher per‑capita equipment funding means undergraduates can use more advanced instruments for independent projects. This offers greater potential to produce publications, which is particularly relevant for those planning to pursue a research master’s or a PhD in Europe or the US. That said, CityU’s laboratories in wireless communications and terahertz technology are equally top‑tier in their specific niches, albeit with a narrower application scope.

Q: PolyU graduates’ average salary is less than HK$200 higher. Why does the median starting salary gap reach HK$1,500?
A: The average salary includes a large number of non‑core engineering roles (such as technical sales and management trainees), which compresses the gap on both ends. The median more accurately reflects the remuneration in core engineering positions. A higher proportion of PolyU graduates enter high‑paying utilities such as power, railway, and aviation, hence the wider gap at the median. Choosing a career sub‑specialism is crucial.

Q: Once an IANG visa is obtained, do the employment differences between engineering graduates from the two universities persist?
A: Yes, they do. According to ImmD data and LinkedIn alumni path analytics, the proportion of engineering graduates still working as engineers in Hong Kong five years after graduation is 68% for PolyU and
