The Civil Service Bureau (CSB) launches Digitalised BLNST in May 2025 for prospective applicants for civil service jobs requiring degree or professional qualifications to take the Basic Law and National Security Law Test (BLNST) (Degree / Professional Grades) at their own selected timeslots throughout the year.  In view of the launch of Digitalised BLNST, with effect from June 2025, the CSB will no longer organise the paper-based BLNST on the same day of the Common Recruitment Examination (CRE) in Hong Kong.  

The examination format, duration and content of Digitalised BLNST are identical to those of the paper-based BLNST.  The only change is that the test would be conducted by computer and the results of Digitalised BLNST will be issued by e-mail to the candidates in the form of electronic result certificates on the same day as the examination.。

• Examination Schedule

  Digitalised BLNST is conducted from Monday to Friday (except public holidays) at the Recruitment Centre, General Grades Office (Address: 37th Floor, Revenue Tower, 5 Gloucester Road, Wanchai, Hong Kong). There are six examination timeslots per day. Limited quotas will be available on a first-come, first-served basis. Applicants can choose the timeslot for Digitalised BLNST to be conducted in the coming 8 weeks from the day of application. The earliest date that can be selected is the next working day.

• Suspension Period

  Digitalised BLNST has a three-month suspension period. If an applicant is absent from the examination or has not attained a pass result in the examination, he / she can only take Digitalised BLNST again three months after the date of absence or the date of failing the examination.

• How to apply

  Applicants must submit the application through Digitalised BLNST online application system. Upon completion of application procedures, applicant will be provided with an application reference number immediately. A confirmation e-mail will also be sent to the applicant’s e-mail address.
