CISI IISI common mistakes
CISI IISI · Understand the traps and how to avoid them.
Treating 'client best interests' as a vague aspiration and choosing the answer that merely satisfies disclosure or suitability, rather than the one that prioritises the client's outcome over the firm's interest.
Candidates learn disclosure and suitability as separate rules and miss that the CISI IISI ethics and professional standards domain expects the 'best interests' principle to override commercial convenience. Under exam pressure, the familiar 'disclose and proceed' option looks correct because it is a recognised regulatory tool.
What to do instead
Before answering any ethics question, ask: 'Whose interest does this option protect first?' Eliminate options that protect the firm, the adviser or a third party before the client, even when they include disclosure or documentation. Practise with short scenarios where disclosure is present but the outcome still disadvantages the client, and note that best interests is an outcome test, not a paperwork test.
Confusing the roles of the FCA, PRA, FOS, FSCS and the Money Advice Service equivalent bodies, and selecting the wrong body as the first point of escalation for a client complaint or a regulatory breach.
The financial services industry and its regulation domain contains many named bodies with overlapping-sounding functions. Candidates memorise acronyms without mapping each to a distinct function (prudential regulation, conduct regulation, dispute resolution, compensation, guidance), so similar-sounding options become interchangeable under time pressure.
What to do instead
Build a one-page table with columns for body, statutory objective, who it regulates or protects, and the trigger for contacting it. Learn the boundary cases: FOS handles eligible complaints after the firm's internal process; FSCS pays compensation when a firm fails; the FCA handles conduct and market abuse reports. Test yourself by writing the first body you would contact for ten different scenarios without looking at the table.
Applying the wrong suitability or appropriateness test to the wrong product or service, for example treating a non-advised sale of a non-complex product as requiring a full suitability report.
Candidates conflate the advice and non-advice pathways and the complex and non-complex product categories. The exam often presents a scenario with a product type and a service type, and the candidate answers from memory of one pathway rather than reading both dimensions in the question.
What to do instead
Create a two-by-two grid of advised versus non-advised and complex versus non-complex, and write the required client information and records in each cell. Before selecting an answer, underline in the question whether advice was given and whether the product is complex. Rehearse with scenarios where the client is experienced versus inexperienced, because the appropriateness test depends on both product and client.
Mixing up the order and ownership of the transaction and settlement chain, such as naming the wrong party as responsible for trade confirmation, settlement or custody of assets.
Investment products, markets and operations questions use precise operational terms (execution, clearing, settlement, custody, corporate actions) that candidates learn as a list rather than as a sequence. Without a mental timeline, the roles of broker, exchange, clearing house, settlement system and custodian blur together.
What to do instead
Draw the lifecycle of a trade from order capture to settlement and custody, labelling which party acts at each step and who bears which risk. Then answer operations questions by locating the event on that diagram before reading the options. Pay particular attention to the difference between clearing (counterparty risk management) and settlement (exchange of cash and securities), and to the custodian's role in safekeeping rather than execution.
Choosing the option that describes what a firm is permitted to do rather than what the individual employee must do when facing a conflict of interest, inducement or personal account dealing scenario.
The integrity, conduct and client treatment domain tests personal conduct, but candidates often answer from the firm's policy perspective because the question is framed around a firm activity. Permitted firm behaviour and required individual behaviour are different standards, and the exam deliberately offers both as plausible options.
What to do instead
When a question names an individual (adviser, dealer, analyst, manager), filter options by what that person must personally do: decline, escalate, disclose to a specific person, or abstain. Reject options that only describe a firm-level control such as 'the firm has a conflict of interest policy'. Practise rewriting firm-level controls as individual actions so the distinction becomes automatic.
Misapplying the client money and assets rules, for example assuming client money can be used to cover a shortfall in another client's account or that client assets can be held in the firm's own name.
Candidates remember that client money must be segregated but not the consequences of that principle. The exam tests the boundary: what may be deducted, when money ceases to be client money, and how title and registration work for safe custody assets. These are counter-intuitive details that general knowledge does not supply.
What to do instead
Learn the client money rules as a set of prohibitions and permissions rather than a narrative: what may be paid out of client money, when money leaves the client money regime, and how safe custody assets must be registered and reconciled. Answer client money questions by asking whether the proposed action creates a shortfall for another client or commingles firm and client funds, and eliminate any option that does either.
Ignoring the timing element in market abuse and disclosure questions, such as treating inside information as usable once it is 'about to be' announced or assuming disclosure obligations are satisfied by informing a select group of clients.
Market abuse rules turn on precise definitions of inside information and on when disclosure is required. Candidates focus on the information itself and overlook the conditions about non-public status, likely price effect and the requirement for effective public disclosure, so they pick options that describe selective or premature disclosure.
What to do instead
Memorise the cumulative conditions for inside information and the permitted behaviours (market soundings, accepted market practices, legitimate business reasons). For each scenario, test every condition explicitly rather than judging the information as 'sensitive'. In disclosure questions, ask whether the disclosure is to the market as a whole and whether it is simultaneous for all recipients; eliminate selective disclosure options even when recipients are under confidentiality.
Confusing the different complaints and redress timelines, such as the eight-week complaint handling period, the six-month window for referring to the Financial Ombudsman Service, and the time limits for bringing a claim.
Several numeric time limits appear across the conduct and regulation domains, and candidates learn them as isolated numbers without the event each is measured from. The exam offers the right number attached to the wrong starting event, which defeats pure number memorisation.
What to do instead
For every time limit, record three things: the number, the event that starts the clock, and the consequence of expiry. Group them by process (internal complaint handling, ombudsman referral, limitation periods) rather than by number. When answering, state the start event in your own words before checking the options, and reject any option whose start event differs from the one in the question.
Selecting an investment product answer based on the product's name or headline feature without checking the underlying risk, tax treatment or investor eligibility described in the question.
Product names in the investment products domain sound descriptive, so candidates assume the name carries the risk and tax profile. Questions often add a detail such as the investor's tax status, income need or time horizon that changes which product is appropriate, and candidates answer from the product label instead of the stated facts.
What to do instead
Read the client facts before reading the product options, and write down the client's objective, time horizon, risk tolerance and tax position. Then evaluate each product against those written criteria rather than against its name. For each major product type, prepare a short profile of its risk, liquidity, tax treatment and typical investor, and use that profile to eliminate options that fail one client criterion.
Treating 'know your customer' and anti-money-laundering checks as a one-off onboarding step, and choosing answers that permit simplified due diligence for all retail clients or that ignore the need for ongoing monitoring.
Candidates remember customer due diligence as a form-filling exercise at account opening and forget the risk-based approach, enhanced measures for higher-risk situations and the requirement for ongoing monitoring. The exam tests the exceptions and the ongoing obligation, which are not part of the basic onboarding narrative.
What to do instead
Learn customer due diligence as a cycle: identify, verify, assess risk, monitor, and update. For each scenario, ask what risk level the customer presents and whether simplified, standard or enhanced measures apply. Reject any option that applies simplified measures to a higher-risk customer or that treats verification as complete at onboarding with no monitoring. Practise with politically exposed persons, correspondent relationships and unusual transaction patterns.
