About the CIC Grade A Electrical Trade Test Exam
The CIC Trade Test for Grade A Electrical Work assesses craft skill and safe-work knowledge for low-voltage fixed electrical installations with approved loading not exceeding 400 A (single or three phase), matching the EMSD Grade A Registered Electrical Worker scope. Passing the written and practical parts yields a CIC Trade Test Certificate that, together with the required qualifications and experience, can support an EMSD Grade A REW registration application. The certificate itself is not an EMSD registration.
Assessment
Two-part trade test: (1) Written technical knowledge test — 100 MCQs in 75 minutes (Unit 1 Legislation & Codes of Practice: 20 questions; Unit 2 Craft, Safety & Ethics: 80 questions) plus a wire colour identification test; candidates must pass written (including colour ID) before booking practical. (2) Practical craft test — four designated tasks in about 6 hours (fixed installation wiring, completion testing/WR1 with fault finding and motor winding simulation, cable coupler wiring, and motor control-panel wiring); Paper A or B assigned randomly on the day.
Time Limit
Written: 75 minutes. Practical: about 6 hours for four tasks.
Passing Score
Written: ≥70% on Unit 1 (20 Qs) and ≥60% on Unit 2 (80 Qs), plus pass the wire colour identification test. Practical: each task ≥60/100, average ≥75/100, key technical criteria met, no serious technical/safety failures, and safety score ≥6/10. Both parts must be passed to receive the CIC certificate.
Exam Fee
HK$100 written (ELW) + HK$400 practical (ELA) per CIC application form revised August 2025; CIC may revise fees without notice. Employment/student visa holders pay 3× basic fee. (Hong Kong Construction Industry Trade Testing Centre (HKCITTC), Construction Industry Council (CIC))

Frequently Asked Questions
What is the CIC Trade Test for Grade A Electrical Work?
It is a written and practical trade test run by the Hong Kong Construction Industry Trade Testing Centre under the CIC. It assesses skills and safe-work knowledge for low-voltage fixed electrical installations with approved loading not exceeding 400 A. A pass certificate, with the required experience and qualifications, can support an EMSD Grade A Registered Electrical Worker application, but the CIC certificate is not itself an EMSD registration.
How is the written test structured and what score do I need?
The written technical knowledge test has 100 multiple-choice questions in 75 minutes: Unit 1 Legislation & Codes of Practice (20 questions, need ≥70% correct) and Unit 2 Craft, Safety & Ethics (80 questions, need ≥60% correct). You must also pass a wire colour identification test; failing colour ID fails the whole written paper. You must pass written before booking the practical.
What does the practical test involve?
In about 6 hours you complete four designated tasks covering fixed installation work (conduit bending, 13A socket radial or ring wiring, lighting or related circuits), completion testing with Form WR1 plus remote fault finding and simulated three-phase motor winding connections, cable coupler wiring, and three-phase motor control-panel wiring (forward/reverse or star-delta). Each task needs ≥60/100, average ≥75/100, key criteria met, and a safety pass (≥6/10).
How much does the CIC Grade A trade test cost?
The CIC application form revised August 2025 lists HK$100 for the written test (ELW) and HK$400 for the practical test (ELA). CIC may revise fees without prior notice. Holders of employment or student visas pay three times the basic fee.
