Failing a CISI exam inside your firm's deadline
"I have to pass within four weeks of hitting the desk. What happens if I don't?" It is one of the most common questions asked by people starting regulated roles, and it usually gets answered with reassurance rather than information. We cannot tell you what your employer will do. We can tell you exactly what the Chartered Institute for Securities and Investment (CISI) rules allow, and that turns out to be the part that changes the plan.
The mechanics, which nobody tells you up front
| Question | What the rules say |
|---|---|
| How soon can I resit? | CISI's re-sits policy states that for a multiple-choice assessment you must wait 96 hours before resitting. An older policy document for computer-based testing phrases it as three clear days — a Thursday sitting giving a Monday resit. Check which applies to your booking route. |
| What does a resit cost? | The full exam fee again. There is no reduced resit rate, so a second attempt costs what the first did. |
| Does a pass expire? | No. Once passed, the pass remains with you indefinitely. |
| Can I resit something I already passed? | Within twelve months of the pass you need CISI's permission. After twelve months you can simply book it. |
| Is there a limit on attempts? | Third-party guides mention a cap within a rolling twelve months and a rest period after several attempts. We could not confirm the detail in CISI's own published policies — ask CISI directly if you think you may approach it. |
What the 96-hour rule actually means for a four-week deadline
Work it through. Sit the exam in week one. If it goes badly you know immediately — these are computer-based multiple-choice papers and the result is not a six-week wait. Four days later you can sit it again, with the enormous advantage of having seen how the questions are actually worded. There is room in a four-week window for more attempts than most people assume.
That reframes the problem. The panic question is "what if I fail?" The useful question is "am I booking early enough that a failure is survivable?" Booking in week one of a four-week window and booking in week four are very different levels of risk, and the choice is entirely yours.
What we cannot tell you
Whether your firm would actually withdraw an offer, extend the deadline, move you to a non-regulated seat, or simply have a conversation — that is your employer's policy, your contract and your supervisor, and it varies enormously between firms and between roles. Anyone on the internet telling you confidently what your bank will do, including us, is guessing.
What is generally true is that the deadline usually exists because the role is regulated: there is work you cannot be signed off to do until the qualification is held. That framing is worth holding on to, because it means the firm's interest is in you passing, not in catching you out. It is also why asking your supervisor early is a reasonable thing to do rather than an admission of weakness.
If you have already failed once
- Book the resit before you start revising. The 96-hour clock only helps if something is in the diary.
- Work out whether you failed on knowledge or on wording. They need completely different fixes. If you knew the material but misread what was being asked, more reading will not help and more practice questions will.
- Find out where the marks are. Regulatory syllabuses are not weighted evenly. Revising every chapter equally is the most reliable way to under-prepare the two or three chapters that carry half the paper.
- Tell your supervisor before they find out from the system. This is consistently the advice given by people who have been through it.
Which exam are you sitting?
If it is the Capital Markets Programme — UK Financial Regulation plus Securities or Derivatives — we do not sell preparation for those units, and you should use what your employer provides. See does your employer pay for your CISI exams? for what to ask them.
If it is one of the exams we do cover, the free study plans show the real mark weighting chapter by chapter, which is the single most useful thing to know when you are short of time. You do not need to buy anything to use them.
Resit rules, fees and pass validity above were taken from CISI's published candidate policies and checked in November 2026. Policies change and differ by booking route and region — confirm with CISI before relying on any of it. Nothing here is employment advice.
