JAMB CBT Centre Allocation: How the System Assigns Candidates to Examination Venues

I printed my JAMB slip last year expecting Ikeja, since that’s where my cousin registered, and got a centre in Yaba instead. We both lived in the same part of Lagos. We both registered in the same week. I spent an hour trying to figure out what I did wrong before I understood that nothing was wrong. The system just doesn’t work the way most guides describe it.

Almost every article on this topic says the same thing: “JAMB allocates your centre automatically.” That sentence is true, but it tells you nothing. It leaves you thinking your venue was picked out of a hat. It wasn’t. There’s a real structure behind it, built from choices you make weeks before the exam and constraints you never see. Once you understand the four inputs that drive this, the “random” placement stops looking random.

Key takeaways

• Your exam town is the one input you fully control, and JAMB’s own registration guidelines state candidates are posted only to the town picked at registration, never to a different one.
• The exact centre within that town is filled by space and timing, not by your address or how close a centre is to your house.
• Two candidates from the same neighborhood can land at different centres simply because one registered earlier and grabbed a seat at the closer venue before it filled.
• Picking a “group of towns” instead of one single town changes your odds and your risk in a way most candidates don’t realize until slip day.
• You cannot request a specific centre by name. You can only influence the pool of centres you might be drawn from.

The direct answer: how JAMB actually assigns your centre

JAMB’s placement runs on four layers, and each one narrows the pool of centres you could land in before the next layer even applies.

Layer one is your exam town choice. During registration, you pick a town (or a small group of towns) where you want to write the exam. JAMB’s own 2026 registration guidance states plainly that the board does not post any candidate to a town other than the one chosen at registration. This is the only layer where your decision matters directly.

Layer two is centre accreditation within that town. Not every cyber café or computer centre in your town can host the UTME. JAMB runs a separate accreditation process, checking things like CCTV coverage, power backup, and internet stability, and only centres that pass get added to the pool for that town. For 2026, JAMB ran a nationwide accreditation review covering 848 centres, and centres that failed inspection were dropped from the list candidates could be assigned to.

Layer three is capacity per session. Each accredited centre has a fixed number of computer seats and a fixed number of exam sessions it can run per day across the ten-day window. JAMB fills these seats in the order registrations come in. Once a centre’s seats for a session are full, the system moves the next candidate to another centre in the same town, even if that candidate lives five minutes from the first one.

Layer four is your registration timing relative to everyone else’s. Because seats fill on a rolling basis, two people who register in the same week can still get sorted into different centres if one of them registered a few days before the other and the closer centre had already reached its cap.

This is why your cousin three streets away can get a totally different venue. It’s not a mistake. It’s what happens when a fixed number of seats meets a much larger number of candidates choosing the same town.

The town and group of towns decision (the part nobody explains well)

This is the gap that most guides skip completely, and it’s actually the most useful thing to understand before you register, not after.

When you fill the registration form, you don’t always pick one single town. JAMB’s guideline explicitly states that choosing a “group of towns” means you accept being posted to any town inside that group. Some candidates select a group thinking it improves their chances of getting a centre close to home. It can do the opposite.

Here’s the mechanism. A group of towns spreads your possible placement across a wider area. If you pick “Lagos Mainland” as a single town, your placement pool is every accredited, available centre in that specific zone. If you pick a group that includes Mainland, Ikorodu, and parts of Badagry, your pool now includes centres far from where you live, and JAMB can post you to any of them if your home zone fills up first.

A single, specific town gives you a smaller, more predictable pool. A group of towns gives you a bigger pool with more seats available overall, but a wider possible spread if your first-choice area is full.

Choice type	Placement pool size	Predictability	Best for
Single specific town	Small, tightly defined	High, you know the general area	Candidates with one safe, reachable town and no flexibility for travel
Group of towns	Large, spans multiple zones	Lower, could land far from home	Candidates registering late, in areas with centre shortages, or open to traveling

I’d lean toward picking a single town if you have one realistic option within an hour of home. The wider group only makes sense if your local town genuinely lacks enough centres for the number of candidates registering there, which does happen in some states.

Why early registration matters more than people admit

Most guides tell you to “register early to avoid the rush.” That advice is true but incomplete, because it doesn’t explain what the rush actually costs you.

The rush doesn’t cost you a slot in the exam. JAMB will still register you. What it costs you is choice within your chosen town. Centres fill seat by seat, session by session, in the order people register. If you register in the first two weeks, you’re competing for seats against a smaller pool of candidates, so you’re more likely to land in a centre near the city center or close to your registration centre. If you register in the final week, you’re competing against nearly everyone who delayed, and the well-known, well-equipped centres in your town are already full. You get whatever centre still has open sessions, which is often farther out, smaller, or newer to the accreditation list.

JAMB has stated this directly in its guidelines: candidates are warned that their preferred town may no longer have space if they wait too long to register. That’s not generic advice. It’s the system telling you exactly how the seat-filling mechanism works.

A simple decision tool: the Town Choice Checklist

Use this before you select your exam town on the registration form. It’s a hard-threshold checklist, not a vague suggestion list.

• Skip the group-of-towns option if you have one town with at least three or four accredited centres and you can reach it within 60 minutes on exam day.
• Use the group-of-towns option if your home town has fewer than two accredited centres listed, since a small pool fills up fast and leaves you no backup.
• Register in the first two weeks if your town is a major city (state capital, Lagos, Abuja, Port Harcourt, similar), because these towns see the heaviest registration volume and fill the closest centres first.
• Register any time within the window if your town is smaller and less commonly picked, since the seat pressure is lower.
• Avoid picking your registration centre’s town purely out of convenience if a different town is genuinely closer to where you’ll be living on exam day. Your registration centre and your exam centre don’t have to match, and many candidates forget this.

Run through these five points once, and you’ll make a more informed town choice than most candidates who just pick whatever feels familiar.

What you cannot influence, no matter what anyone tells you

A few things sit completely outside your control, and it helps to know this so you don’t waste energy trying to change them.

• You cannot request a specific centre by name. The system doesn’t take centre preference as an input, only town preference.
• You cannot trade or swap your assigned centre with another candidate, even if you both registered in the same town.
• You cannot pay an agent to “secure” a particular centre. JAMB’s own communications warn candidates against agents who claim this kind of access, since centre assignment happens through the seat-filling process, not manual selection.
• You cannot appeal a centre assignment based on distance alone. JAMB treats this as an operational outcome of capacity, not an error to correct.

If someone tells you they can get you a specific centre for a fee, that claim doesn’t match how the assignment mechanism works, and it’s worth treating with real skepticism.

When JAMB does step in and change things

The system isn’t completely rigid. There have been cases where JAMB adjusted town configurations mid-cycle, including a temporary suspension of town selection in Ekiti State for the 2026 cycle while the board made adjustments. This shows that the board does monitor capacity issues at the town level and will intervene when a town’s centre options need rework, rather than letting candidates register into a town that can’t actually serve them.

This kind of adjustment is rare and announced through official channels, not something you can request for your own case. But it confirms that the four-layer system described above is actively managed, not just left to run on autopilot.

Troubleshooting: common situations candidates run into

My centre is far from where I registered. This is normal and expected. Your registration centre and exam centre are two separate things. Registration just needs any accredited centre with working biometric equipment. Your exam centre depends on the town you picked on the form, not where you registered.

My friend and I picked the same town and got different centres. This comes down to seat capacity per session. Centres have caps. Once one centre’s sessions fill, JAMB moves the next registrant to another centre in the same town pool.

I want to change my centre after seeing my slip. In nearly every documented case, this isn’t possible once the slip is issued. The placement reflects the seat-filling process at the moment you registered, and reversing that for one candidate would require pulling a seat from someone else who already has one.

I selected a group of towns and got placed somewhere I didn’t expect. Re-read what you selected. A group of towns means JAMB can place you in any town within that group, and many candidates only realize after registration that they picked a wider net than they meant to.

My exam date came out different from my friend’s, even in the same centre. The ten-day examination window runs multiple sessions per day across many centres, so candidates in the same centre often write on different days or times depending on when their session slot was assigned.

Frequently asked questions

Does living closer to a centre give me priority for that centre? No. Distance doesn’t factor into the assignment mechanism. Priority comes from your town selection and your registration timing relative to centre capacity, not your home address.

Can I find out which centres exist in my town before I register, so I can guess my odds? Yes. JAMB publishes lists of accredited centres by state, and checking how many centres serve your intended town gives you a real sense of how much competition for seats you’re walking into, which ties directly into the Town Choice Checklist above.

If a centre fails accreditation close to my exam date, does that affect candidates already assigned there? JAMB’s accreditation reviews happen ahead of the exam period specifically to avoid this, removing centres that don’t meet standards before assignments are finalized rather than after.

If you’re still weeks away from registering, the single most useful thing you can do with everything above is pick one realistic town, register inside the first two weeks of the window, and skip the group-of-towns option unless your area genuinely has too few centres to handle the demand.
