About JKSSB SI (Telecom)

The JKSSB Sub Inspector (Telecommunication) examination recruits technical Sub Inspectors for the Telecommunication wing of the J&K Police under the Home Department of J&K UT. This is a separate cadre from the Executive Sub Inspector post — it is advertised under its own notification and carries a heavily technical, electronics-and-communication-focused syllabus. Advertisement Notification 11 of 2025 (dated 26 November 2025) announced this round of recruitment; the written examination has not been conducted yet and is expected around 2026, with the exact date to be notified separately by JKSSB.

The written examination consists of 100 objective-type MCQ questions, each carrying 2 marks, for a total of 200 marks in 120 minutes, with negative marking of 0.5 marks per wrong answer. The paper is split into two parts: Part A — General Awareness, Aptitude & Communication (60 marks) and Part B — Technical / Professional Knowledge (140 marks). The technical weightage is the defining feature of this exam: 70% of the marks test electronics, communication systems, computer networking, cyber security and emerging technologies.

Because Part B (140 of 200 marks) is technical, an engineering or diploma background in Electronics, Communication, Computer Science or IT is a strong advantage. Candidates should treat this as a technical exam first and a general-awareness exam second — mastering Communication Systems, Electronic Devices, Digital Electronics and Computer Networking is essential to clear the cut-off.
