Step 2

The Driver CPC case study test for bus drivers

Step 2 of Driver CPC is a different shape of exam from the theory test. It has two pass conditions rather than one, and meeting only the easier of them is still a fail.

How it works

The bus case study test asks you to look at three real-life situations a professional CPC bus driver might face. It is computer-based, and works as follows:

The test takes about 120 minutes.

Both conditions, at the same time. Scoring 14, 14 and 4 gives you 32 overall — comfortably past 28 — and is still a fail, because one situation fell below 5. Scoring 5, 5 and 5 clears every floor and fails on the overall. Neither condition can carry the other.

Where you can sit it

You have the option of sitting the case study test at home or at one of the forty-plus theory test centres nationwide. Sitting it at home is convenient, but it makes two uninterrupted hours your responsibility, and two hours is long enough for a household interruption to cost you the result.

What you need first

You must have passed the Driver CPC theory test (Step 1) in the relevant category before you can sit your case study test — see the bus theory test.

Results and the certificate

You are given a score report telling you whether you passed or failed.

On a pass you receive a Driver CPC case study test certificate valid for up to two years, and you should apply for a learner permit within that time. After two years the certificate is no longer valid and you will have to pay for and sit the test again.

On a fail the score report comes with feedback on where you went wrong. You can book another case study test straight away, but you cannot take it for another three clear working days.

Rescheduling and cancelling

A cancellation or rescheduling request must be submitted at least five days before your test booking, and those five days must include three working days. This is a different rule from the ordinary theory test’s notice periods, so do not assume they match.

What the bus scenarios tend to involve

The situations are written around the working day of a professional passenger driver, which means the people on board are usually part of the problem rather than background detail:

In almost all of them the safe and compliant answer costs time, and the tempting answer saves it. That tension is the point of the format.

How to prepare

Frequently asked questions

What is the pass mark for the bus Driver CPC case study test?

Two conditions, both of which must be met: at least 5 out of 15 in each of the three case studies, and at least 28 out of 45 overall. Meeting only one of them is a fail.

How long does the Driver CPC case study test take?

About 120 minutes for three real-life situations with 15 questions each. Some secondary sites quote around 135 minutes; the RSA’s own bus and truck pages both say about 120.

Can I sit the bus case study test at home?

Yes. You have the option of sitting it at home or at one of the forty-plus theory test centres nationwide.

How soon can I retake the case study test?

You can book another test straight away, but you cannot take it for another three clear working days. Your score report includes feedback on where you went wrong.
