How to Talk About Obligation & "Should"

1. Why This Skill Matters

"Should" questions are opinion questions in disguise, and examiners score them the same way: on whether you state a clear position, back it with reasoning, and sound like a real person rather than a rulebook. A flat yes/no answers the question technically but shows nothing; an absolute "always/never" statement sounds rigid and unconsidered; and a should-statement with no consequence attached sounds like an unexplained rule rather than an opinion. This guide fixes all three problems with one flexible toolkit.

2. How IELTS Tests This Across All Three Parts

• Part 1: short obligation questions about everyday life — "Should children be allowed to choose their own clothes?" "Should people be given more holiday?" These need a quick should/shouldn't statement plus a one-line reason.
• Part 2: cue cards rarely ask for should-opinions directly, but describing a rule or a piece of advice you were given often calls on the same should/shouldn't + reason structure.
• Part 3: this is where obligation questions get serious — social policy, education systems, workplace rights. These need the fuller toolkit: qualifiers, exceptions, and consequence clauses.

3. The Core Toolkit

3.1. Turn the yes/no into a full should/shouldn't sentence

A bare "yes, I think so" only confirms the question — it doesn't show you actually have an opinion. Restate who + should/shouldn't + do what:

• Yes, I think workers should be given longer paid holidays.
• No, I don't think students should always be made to wear a uniform.
• Certainly not — I don't think parents should push their kids to win prizes.

3.2. Add one reason with "because"

A should-statement with no reason sounds like a rule with no logic behind it — "because" turns it into an actual argument (borrowed from the giving_opinion move):

• …because so many people do unpaid overtime and barely get any time to rest.
• …because it's part of learning to express your own style.
• …because it can make them anxious about failing instead of motivated to try.

3.3. Soften absolute claims with a qualifier

"Students should always wear uniforms" sounds too extreme to be a genuine opinion. Add a small qualifier — generally, in most cases, probably — so it sounds considered rather than dogmatic:

• I think students should generally be allowed to choose their own clothes.
• Parents should probably keep a close eye on younger children.
• ...although younger children might still benefit from a uniform for practical reasons.

3.4. Name one exception or condition

Alongside the qualifier, naming a specific situation where the rule wouldn't apply proves you've actually thought about the issue, not just repeated a slogan:

• ...although younger children might still benefit from a uniform.
• ...but I think teenagers ought to be given more freedom to make their own decisions.
• ...unless they're old enough to know how to stay safe.

3.5. Add a real consequence

Saying what should happen is only half the argument — adding what would happen if it didn't (or the benefit if it did) is the part that actually demonstrates reasoning:

• If employees never get a proper break, they get exhausted and become less loyal to their company in the long term.
• If students leave school without computer skills, they really struggle to find a decent job afterwards.
• When kids spend too much time online, they often get less sleep and struggle to focus at school the next day.

4. How These Words and Structures Relate to Each Other

The obligation/should toolkit (formula F18) sits directly on top of two other moves already covered elsewhere in this series, and the source data documents both links explicitly:

1. The "because" reason clause is borrowed from giving_opinion (F25) — the exact same single-reason logic used whenever you're asked "what do you think?" applies here; a should-statement is really just an opinion about what ought to happen.
2. The concrete example technique is borrowed from enumerating_examples (listing_examples_types) — naming one specific situation ("students should generally be allowed to choose their own clothes, although younger children...") makes an abstract "should" statement sound grounded rather than generic, the same technique used when listing examples of anything.
3. Internally, F18 also supplies the zero conditional structure ("if + present simple, present simple" — e.g. "if employees never get a proper break, they get exhausted") as the standard way to attach a consequence to a should-statement, and the passive permission structure ("should/shouldn't be given/allowed to/permitted to + verb") as the standard way to phrase what should happen to a group of people, rather than what a group should do to itself.

Together, a complete should-opinion runs: [should/shouldn't + passive permission structure] + [because + reason] + [qualifier] + [exception] + [if/when + zero-conditional consequence].

5. Part 1 in Practice — 5 Topics

Topic	Weak answer	Upgraded answer
Work & career	Yes, I think so.	Yes, I think workers should be given longer paid holidays, because so many people do unpaid overtime and barely get any time to rest.
Education & study	No, not really.	No, I don't think so — students should be permitted to choose their own clothes, because it's part of learning to express your own style.
Friends & family	Yes, I think so.	Certainly not — I don't think parents should push their kids to win prizes, because it can make them anxious about failing instead of motivated to try.
Education & study	Students should always wear uniforms.	I think students should generally be allowed to choose their own clothes, although younger children might still benefit from a uniform for practical reasons.
Friends & family	Parents should always control everything their children do.	Parents should probably keep a close eye on younger children, but I think teenagers ought to be given more freedom to make their own decisions.

6. Part 2 in Practice — A Full Model Monologue

Cue card: Describe a rule you think schools should introduce. You should say: what the rule would be, who it would affect, why you think it's necessary, and explain how you think it would help students.

"One rule I genuinely think schools should introduce is compulsory digital literacy classes, starting from a fairly young age. I think students should definitely be taught basic computer and internet safety skills, because so many parts of daily life now depend on being comfortable with technology, and not every student has that support at home.

This would mainly affect younger students, probably from around age ten onwards, although I think the content would need to change as they get older — younger children might just need the basics of using a computer safely, while older teenagers should probably be taught more about things like managing their digital footprint or spotting online scams.

I think it's necessary because, if students leave school without these skills, they really struggle later — whether that's applying for jobs online, understanding how to protect their personal information, or even just communicating professionally over email. Having said that, I don't think this should replace other subjects entirely; it would probably work best as a short, regular class alongside the existing curriculum.

As for how it would help, I genuinely believe it would make a big difference to students from less well-off backgrounds in particular, since they're less likely to have this knowledge passed down at home. Overall, I think it's a rule that would benefit almost everyone, even if it took a bit of adjustment to fit into the existing school day."

7. Applying the Skill at Part 3 Register

Part 3 obligation questions are broader and often ask about society or policy rather than personal life, so the toolkit needs a slightly more formal register and more careful hedging.

Q: Do you think governments should be responsible for making sure everyone has a decent standard of living?

"I'd say governments should generally play a significant role in this, because leaving it entirely to individuals tends to widen inequality rather than reduce it. That said, I don't think it's purely the government's responsibility — communities and employers arguably ought to share some of that obligation too. If a government provides absolutely nothing in the way of support, you tend to see much higher levels of poverty and social unrest, so there's a fairly strong practical argument for at least a basic safety net."

Q: Should companies be required to give employees more say in how the company is run?

"I think companies should probably be encouraged to give employees more input, particularly on decisions that directly affect their day-to-day work, because employees who feel heard tend to be considerably more motivated. I wouldn't go as far as saying every decision should be put to a vote, though — some strategic decisions probably do need to sit with management. If staff are never consulted at all, you often end up with high staff turnover and low morale, which ultimately costs the company more in the long run."

8. Academic Words (AWL)

Word	Definition	Example
considerable	fairly large in amount	Uniforms have a considerable impact on how equal students feel.
ultimately	in the end; finally	Ultimately, the decision should depend on the age group involved.
perspective	a way of viewing a situation	From a parent's perspective, some level of control makes sense.
notion	an idea or belief	The notion that rules should never have exceptions is unrealistic.
valid	reasonable and well-founded	That's a valid point about fairness between students.
justify	to show something is reasonable	You should justify any should-statement with a clear reason.
presumably	used to state an assumption	Presumably, younger children need more supervision than teenagers.
obligation	a duty or requirement to do something	Employers have an obligation to provide safe working conditions.
enforce	to make sure a rule is followed	It would be difficult to enforce such a rule fairly.
exempt	free from an obligation or rule	Younger children could be exempt from this particular requirement.
consensus	general agreement	There's a general consensus that overtime should be limited.
regulation	an official rule controlling behaviour	New regulations on working hours were introduced last year.

9. Idioms

• draw the line — to set a limit on what's acceptable: "I'd draw the line at controlling what teenagers wear outside school."
• toe the line — to obey rules exactly: "Younger children are usually expected to toe the line more than teenagers."
• bend the rules — to allow a small exception: "Teachers sometimes bend the rules for students dealing with personal problems."
• a double-edged sword — something with both good and bad effects: "Strict school rules can be a double-edged sword."
• set a precedent — to establish an example others will follow: "Allowing one exception could set a precedent for others."

10. Native-Speaker Ways of Saying It

• "I mean, ideally, X should..." (softens a should-statement into a considered ideal rather than a demand)
• "There's definitely an argument for..." (introduces a should-opinion without sounding too forceful)
• "It's a bit of a grey area, but I'd lean towards..." (natural hedge for genuinely uncertain should-questions)
• "At the end of the day, I think..." (introduces a final, considered opinion after weighing both sides)
• "Realistically, X probably needs to..." (a practical, grounded way to state an obligation)

11. Common Mistakes at a Glance

Mistake	Why it's a problem	Fix
"Yes, I think so" with no restatement	Only confirms the question; shows no real opinion	Restate as a full should/shouldn't sentence
Should-statement with no reason	Sounds like an arbitrary rule	Add one reason with "because"
"Students should always..."	Sounds rigid, not like a genuine opinion	Add a small qualifier: generally, probably, in most cases
No exception named	Sounds like you haven't actually considered the issue	Name one situation where the rule wouldn't apply
No consequence attached	Doesn't show the reasoning behind the should-statement	Add an "if/when" clause showing what happens without the rule
Overly formal "one should"	Sounds unnatural and distant in spoken English	Use "people should," "students should," or a specific group
Using "must" for a personal opinion	Makes an opinion sound like a stated rule or law	Reserve "must" for genuine legal or safety requirements; use "should" for opinions

11.5. Grammar Note: "Should" vs "Ought To" vs "Must"

These three modals all touch on obligation, but they carry different weight and register:

• should / shouldn't is the default choice for personal opinions about what's advisable — it's a recommendation, not a rule. Almost every should-opinion in this guide uses this modal because it sounds like a considered view rather than a command.
• ought to / ought not to is a close synonym of "should," slightly more formal, and slightly more common in written or careful spoken English — "Workers ought to be treated more fairly" sounds marginally more deliberate than "workers should be treated more fairly," but the two are largely interchangeable in a Speaking test.
• must / mustn't is much stronger — it implies a rule, law, or genuine necessity rather than an opinion, and using it for a personal should-opinion can sound overly forceful. Compare "Students must wear a uniform" (states a rule as fact) with "Students should be allowed to choose their own clothes" (states an opinion about what's advisable). In a should-question, reaching for "must" too often makes your answer sound less like an opinion and more like you're stating an existing law.

A useful habit: default to "should" for your main opinion, use "ought to" occasionally for register variation, and save "must" only for situations that really are non-negotiable (health and safety, legal requirements) rather than matters of personal judgement.

14. Glossary

• obligation — a duty or requirement to do something
• passive permission structure — the grammar pattern "should/shouldn't + be + past participle" (e.g. "should be given," "shouldn't be allowed")
• zero conditional — "if/when + present simple, present simple," used for general truths and consequences
• qualifier — a word that softens a claim (generally, probably, in most cases)
• exception — a case where a general rule doesn't apply
• modal verb — a verb like should, must, or ought to, used to express obligation, possibility, or permission rather than a plain action
