What the CRE and BLNST are
Hong Kong’s civil service does not hire degree and professional grade staff on the strength of a CV and an interview alone. Most of these posts require a candidate to have cleared the Common Recruitment Examination, known as the CRE, and every civil service job, at any grade, requires a pass in the Basic Law and National Security Law Test, the BLNST. The two are administered together, by the Civil Service Bureau, but they test different things and different posts require different combinations of them.
This is a genuinely written, competitive, multiple-choice examination, not a psychometric screening step or an interview, and it recurs on a published cycle rather than as a one-off recruitment drive.
Who sits it
Applicants for degree or professional grade civil service posts sit the CRE. Eligibility covers holders of a degree, holders of a professional qualification that meets the entry requirement of the post applied for, and undergraduates expected to graduate in the current or next academic year. Every applicant also needs a Hong Kong Identity Card and must be 18 or older.
Because these criteria are set once and apply across a recruitment cycle rather than per department, most candidates aiming at degree or professional grade government jobs will sit the same CRE regardless of which department or bureau they are ultimately applying to; it is the individual recruiting department’s own notice that decides which papers matter for that specific post.
What the CRE tests
The CRE has three papers, each 45 minutes and each multiple choice: Use of English (UE), Use of Chinese (UC), and an Aptitude Test (AT) that assesses reasoning ability rather than either language. Not every candidate needs to sit every paper. A Level 4 result in English Language at the Hong Kong Diploma of Secondary Education Examination is accepted as equivalent to a Level 1 pass in the UE paper, and the same equivalence applies between Level 4 Chinese Language at the HKDSEE and Level 1 in the UC paper, so candidates who already hold that school-leaving qualification can be exempted from sitting the corresponding CRE paper again.
The AT paper matters differently from UE and UC: a pass in it is an eligibility requirement only for some degree or professional grade posts, not for all of them. Whether a specific vacancy requires an AT pass is stated in that vacancy’s own recruitment notice, not in a single blanket rule across the whole civil service.
What the BLNST tests
The BLNST is a separate, shorter paper: 20 multiple choice questions, bilingual in English and Chinese, over 35 minutes, with no negative marking. A candidate who answers at least 10 of the 20 questions correctly is deemed to have passed. Unlike the CRE’s three papers, a BLNST pass is required for every civil service job, not only degree or professional grade posts; a version for non-degree, non-professional grades sits at or above completion-of-secondary-education level and follows the same 20-question, 35-minute, bilingual format. The Civil Service Bureau also runs a digitalised version of the BLNST for added convenience, alongside the paper-based sitting.
When it is held, and where
The CRE and BLNST are held on a recurring cycle rather than once a year on a fixed date; recent sittings include one held in Hong Kong on 6 June 2026, and an October 2026 sitting for which applications ran from 12 September to 2 October 2026, tentatively scheduled for 3 October 2026. For candidates studying or living abroad, the Civil Service Bureau also runs the CRE together with the paper-based BLNST (for degree/professional grades) outside Hong Kong on the same day as one of the local sittings, in Beijing, Shanghai, London, New York, Toronto, Vancouver and Sydney. Exact dates shift cycle to cycle, so treat any specific date here as belonging to that cycle rather than a fixed annual calendar, and check the Civil Service Bureau’s own CRE page before relying on it.
Fees and what to bring
There is no application fee for the CRE or the BLNST. Candidates need their Hong Kong Identity Card and the admission notice issued for that specific sitting; mobile phones and other electronic devices are not permitted in the examination room.
After the exam
Passing the CRE and BLNST does not by itself secure a job. It clears the written-examination requirement that most degree and professional grade civil service recruitment sets as a gate before shortlisting, interview and appointment, which each recruiting department runs separately once the written results are in hand.
