Civil Defence Recruitment CBT 2025: What You Must Know Before the Exam

 The civil defence recruitment exercise under the CDCFIB has reached a critical stage: candidates shortlisted for various paramilitary services are now gearing up for the Computer-Based Test (CBT). 

Whether you applied for the Nigeria Security and Civil Defence Corps (NSCDC), Nigeria Correctional Service (NCoS), Nigeria Immigration Service (NIS) or the Federal Fire Service (FFS), this guide will walk you through what you should know for the CBT phase.

✅ What is the CBT?

The CBT is an online screening test for shortlisted applicants. The Board has announced that across all 36 states and the FCT, selected candidates will be called to take the test. 
The aim is to assess general knowledge, English language skills, quantitative reasoning and computer literacy.

 Key Eligibility & Application Notes

• Applicants must be Nigerian by birth and between the ages of 18 and 35 years. 

• Minimum height: 1.65m for men, 1.60m for women. 

• Clean criminal record, medically/physically fit and no history of financial embarrassment.

• Application is completely free; beware of fraudsters. 

🧭 How to Prepare for the CBT

1. Practice past questions: Familiarize yourself with the format and timing.

2. Improve your computer literacy: Being comfortable with a keyboard, mouse and online environment helps.

3. Review key subjects: English comprehension, numerical reasoning, general knowledge and basic logic.

4. Avoid distractions: On the day of the test, use a stable internet connection and a suitable environment.

💡 Why This Matters

CBTs have become a critical gatekeeper for many public-service recruitments in Nigeria. Not just your academic credentials, but your ability to perform under timed, digital-exam conditions can determine success. 
For many applicants, the CBT is first rite of passage before any physical screening or training.

🚨 What to Watch Out For

• Fake websites and scammers: Only rely on the official portal address. 

• Multiple applications: Submitting more than one form may lead to disqualification. 

• Sudden changes: Dates or venues may shift; always confirm from official sources.

 Next Steps After CBT

If you pass the CBT, you’ll typically be invited for:

• Physical screening (fitness test, measurements)

• Medical examination

• Interview or further evaluation

Make sure all your documents (certificates, ID, medical proofs) are ready in advance.
