CISI Introduction to Securities & Investment (UK)
Join thousands of students who passed on their first attempt.
Candidates searching for the CISI Introduction to Securities & Investment often find pages for the International Introduction to Securities & Investment (IISI) instead. They are related foundation qualifications, but they are not interchangeable. The UK version includes UK regulation, tax, savings and advice content that the international route treats differently.
Quick answer: Choose the UK Introduction to Securities & Investment if your employer or qualification pathway specifies the UK unit, or if you need UK regulation and personal-finance coverage. Choose IISI only when the international unit is the stated requirement. Confirm the exact exam title or code before buying study material.
UK ISI versus IISI
| Point | UK Introduction to Securities & Investment | International Introduction to Securities & Investment |
|---|---|---|
| Market perspective | UK foundation with broad market coverage | International foundation with global perspective |
| Regulation | UK regulatory framework and professional integrity | International regulatory principles and local-market adaptations |
| Personal finance | UK taxation, ISAs, pensions, trusts, mortgages and protection | Broader international treatment without the same UK-specific detail |
| Best fit | UK role, UK pathway or employer-specified UK exam | International role or employer-specified international exam |
| Course identifier on this site | CISI ISI | CISI IISI |
The correct choice is not about which qualification sounds more prestigious. It is about the unit required for your role, regulator, employer or wider CISI pathway.

Markets and investments: 34 questions
Economics, equities, bonds, other investments, derivatives and funds make up 34 questions. This is the technical core. Learn how securities are issued, traded, valued and used—not only their definitions.
Equities is the largest chapter. Focus on ordinary and preference shares, primary and secondary markets, corporate actions, trading and settlement. For bonds, connect price and yield, interest-rate exposure, credit quality and redemption. For derivatives, know the distinct rights and obligations created by futures, options and swaps.
UK context: regulation, tax and advice
The UK-specific chapters are the clearest reason not to substitute IISI material. You need current knowledge of the UK regulatory framework, professional integrity, financial crime, complaints and compensation, plus UK taxation and wrappers such as ISAs and pensions.
Version 26 includes current official changes affecting subjects such as FSCS deposit protection, FCA objective wording and ISA treatment. This illustrates why an older “past paper” or international workbook is a poor substitute for the correct current syllabus.
Who should take the UK exam?
The UK unit is likely the right choice when:
- an employer names Introduction to Investment or the UK Introduction to Securities & Investment;
- the unit sits inside a UK-focused CISI qualification route;
- your work requires a foundation in UK regulation and retail financial products;
- your learning outcomes explicitly mention UK tax, ISAs, UK pensions or UK redress arrangements.
IISI may be the better fit when your role is outside the UK and the international unit is recognised or required locally. Do not infer from geography alone: many international employers specify exact CISI units.
How to confirm before registering
- Ask for the full official exam name and any unit code.
- Check the qualification pathway on the CISI website.
- Match the syllabus version to your intended exam date.
- Confirm that your workbook says UK or International as required.
- Check whether a local regulator or employer requires a separate local-regulation unit.
These five checks can prevent weeks of studying the wrong material.
A study plan for the UK version
For an 80-hour plan, allocate about 50 hours to content, 15 to active recall and chapter questions, 10 to timed mixed practice and 5 to final weak-area review. Within content study, give the most time to equities, bonds and funds, while revisiting the UK-specific facts frequently because thresholds and terminology are vulnerable to outdated materials.
Use comparison tables for asset classes and a client journey for advice: circumstances, objectives, risk, suitability, recommendation and review. For regulation and tax, record the syllabus version next to your notes so you do not mix facts from different exam years.
Current-syllabus warning
This article was reviewed for Version 26 in 2026. Always check the official CISI candidate updates and syllabus applicable to your exam date.
If you need the UK unit, visit the CISI Introduction to Securities & Investment UK course page. If your requirement says International, use the IISI course instead.
Final answer
The UK ISI and international IISI share a foundation in markets and investment products, but they serve different requirements. The UK exam’s regulation, tax, wrappers and advice content make the distinction meaningful. Confirm the precise unit first; then prepare from the current syllabus rather than from a similarly named course.
