BLNST Content, Pass Mark & Registration at a Glance
The Basic Law and National Security Law Test (BLNST) is a mandatory entry requirement for Hong Kong government jobs — from degree-grade roles like AO and EO to ACO, clerical and disciplined-services positions. The summary below combines public information from the Civil Service Bureau (CSB) with practical drilling tips so you understand both what is tested and how to revise.
Exam Format: 30 Minutes, 20 Multiple-Choice Questions
The degree/professional-grade BLNST has 20 multiple-choice questions (Chinese and English versions), with a 30-minute limit — about 1.5 minutes per question. Roughly 15 questions cover the Basic Law and about 5 cover the National Security Law. The questions look manageable, but options are often deliberately similar; a single word can flip the meaning, so drilling questions builds the sensitivity that rote reading cannot.
BLNST Pass Mark: 10 / 20 = 50%, Valid for Life
Answering 10 or more questions correctly (50%) is a pass. Crucially, a passing result is permanently valid — once you pass, you never need to retake it when applying for other civil-service posts with equal or lower education requirements. Although the threshold is 50%, questions are drawn at random, so aim for 15+ to keep a buffer for chapters you are less sure of.
Scope: Basic Law + Four NSL Offences
The Basic Law portion spans One Country Two Systems, residents' rights, the Chief Executive, the Legislative Council, the Judiciary, and the contrast between the power of interpretation and the power of amendment. The National Security Law portion focuses on the four offences — secession, subversion, terrorist activities, and collusion with foreign or external forces — plus the distinction between the National Security Committee and the Office for Safeguarding National Security. NSL coverage has been trending upward, so do not skip it.
BLNST Registration & the Digitalised Test
The Civil Service Bureau now runs a digitalised test; degree/professional-grade candidates can sit it year-round at a self-selected time, booking a slot within the next eight weeks on the day of application — first come, first served, and popular slots fill fast. Traditional paper-based sittings (for some grades) are generally held twice a year, around mid-year (May–June) and year-end (Sep–Nov).
How to Check Your BLNST Result
The big advantage of the digitalised test is same-day results — within about 5 minutes of finishing you receive an email with an e-certificate you can download and keep, ideal if you are rushing to submit an application. Paper-based sittings require waiting for the official result release, and your best score counts.
Drill 680+ Questions on the 10-Min BLNST App
Instead of reading the legislation article by article, drill questions in the app: 680+ curated practice questions covering the full Basic Law and National Security Law scope, each with original-text explanations. A timed mock exam (random 20 questions, 30-minute limit) and a mistakes-review mode let you complete a round during a 15-minute commute — 20 questions a day in the month before your exam is enough to build real exam feel.

Basic Law & HKNSL FAQ
Must-know info for BLNST
BLNST is the Basic Law and National Security Law Test, run by the Civil Service Bureau and required for all civil-service posts. It tests the Basic Law and the National Security Law; the degree grade is 20 multiple-choice questions in 30 minutes.
Answering 10 or more of the 20 questions correctly (50%) is a pass. Because questions are drawn at random, aim to consistently score 15+ in practice to stay safe.
Of the 20 questions, about 15 cover the Basic Law and about 5 cover the National Security Law. The NSL section mainly tests the four offences (secession, subversion, terrorist activities, collusion with foreign or external forces) and the difference between the National Security Committee and the Office for Safeguarding National Security.
No. A passing result is permanently valid — once you pass you never need to retake it for other civil-service posts with equal or lower education requirements.
Degree/professional-grade candidates sit the Civil Service Bureau's digitalised test year-round at a self-selected time, booking a slot within the next eight weeks on the application day, first come first served. Some grades still use traditional paper-based sittings, generally held twice a year.
For the digitalised test you receive an email with an e-certificate within about 5 minutes of finishing — same-day results. Paper-based sittings require waiting for the official result release.
Yes. From degree grades like AO and EO to non-degree posts such as ACO, clerical and disciplined services, passing the BLNST is an entry requirement. Posts below secondary-level education usually use oral questions at interview instead.
Yes. A pass obtained from the Civil Service Bureau or the Education Bureau can be used for either. However, tests run by the ICAC or other bodies are not accepted for civil-service applications, so confirm the organiser before sitting.
Very effective. The 10-Min BLNST app has 680+ practice questions covering the full scope, each with original-text explanations. Drilling 20 a day in the month before, plus timed mocks and mistakes review, gets you past the wording traps once you clear 500+ questions.
Focus on the four offences, then clearly separate the National Security Committee (set up by the HKSAR, chaired by the Chief Executive) from the Office for Safeguarding National Security (set up by the Central People's Government) — both are frequently tested. App NSL questions include the original text so repeated drilling makes them stick.
