TLDR
Executive term limits are rules that cap how long a chief executive can stay in office, and they come with real tradeoffs. They can check power, refocus leaders on governing, and open the door to fresh ideas, but they can also push out effective leaders, break policy continuity, and create lame-duck weakness. For AP Comparative Government, you need to explain these advantages and disadvantages and connect them to stability and effective policymaking.

Why This Matters for the AP Comparative Government Exam
This topic sits inside Unit 2, where you study how executive, legislative, and judicial institutions hold and use power. Term limits are a clear example of how an institutional rule shapes stability, legitimacy, and policymaking over time.
The argument writing on this exam rewards a clear, defensible claim backed by specific evidence. Term limits give you a flexible tool for that: you can argue whether they actually constrain executive power, then support your claim using course countries. Because this exam is built on comparison, term limits also let you practice lining up countries by a shared category (such as whether a limit exists, how long it is, or whether it has been changed) and explaining why the difference matters.
Key Takeaways
- Term limits are institutional rules that cap how long an executive can serve. Some countries have strict limits, some allow re-election, and some have weakened or removed limits.
- Advantages: they check executive power and slow the rise of dictators and personality rule, push officeholders to focus on governing instead of campaigning, and open opportunities for new leaders and ideas.
- Disadvantages: they can force out good leaders, give too little time to finish goals, break policy continuity, weaken accountability, create a lame-duck period, block experience-building, and lead to rushed or weak policy.
- You should be able to identify whether each course country has term limits and what they are.
- A term limit on paper does not guarantee limited power in practice. Look at how rules are enforced or worked around.
- When you compare countries, pick a relevant category first, then explain why the similarity or difference matters for stability or policymaking.
Key Terms
- Executive Term Limits: Institutional rules that limit how long an executive can serve in office.
- Example: In Mexico, the president serves a single 6-year term, called a sexenio, with no re-election. This limit is set in the Mexican Constitution.
- Fixed-Term Election System: A system in which election dates are scheduled and announced in advance.
- Example: In the UK, the Fixed-term Parliaments Act (2011) set a default 5-year election cycle unless an early election was triggered under specific conditions.
Executive Term Limits in the Course Countries
Use this chart to keep the six countries straight. Treat the country-specific facts as supporting evidence you can pull into arguments, not as a required list.
| Course Country | Executive Term Limits | Where Established | Notes / Explanations |
|---|---|---|---|
| UK | No formal term limit | Common law (no single written constitution) | No formal limit on the prime minister. The monarch serves for life. If a confidence motion is lost, the government must resign or call a general election. |
| Mexico | One 6-year term (sexenio) | Constitution | President can serve only one term, with no re-election. Term length changed from 4 years to 6 in 1928. |
| Nigeria | Two consecutive 4-year terms | Constitution | Coups have removed presidents at various points in history, separate from term limits. |
| China | Previously a 10-year limit (removed in 2018) | Constitution | The constitution was amended in 2018 to remove the presidential term limit, allowing indefinite service. |
| Iran | Supreme Leader has no fixed-term turnover in practice; president limited to two consecutive 4-year terms | Iranian law | The president is restricted to two consecutive 4-year terms. The Supreme Leader is not removed through term limits. |
| Russia | Two consecutive 6-year terms | Constitution | Term length changed from 4 to 6 years. Putin shifted from president to prime minister and back, a widely cited example of working around the limit. |
The first thing to lock in is simple: be ready to state whether each course country has executive term limits and what they are.
The second thing is to explain the advantages and disadvantages of term limits in two areas: political stability and effective policymaking.
Advantages
- Checks on power: Regular limits reduce the risk of dictators or personality-based rule emerging.
- Focus on governance: Leaders can concentrate on governing instead of constantly campaigning for re-election.
- New ideas: Limits create openings for new leaders with fresh policies and goals, bringing in different backgrounds and generations.
Disadvantages
- Forces good executives out: Popular and effective leaders can be pushed out even with strong public support.
- Too little time: Big policies take time, and limits can cut an executive off before goals are finished.
- Breaks policy continuity: New leaders can reverse a predecessor's priorities, including undoing executive orders.
- Weakens accountability: In a final term, an executive may feel less pressure to answer to voters.
- Lame-duck period: Near the end of a term, an outgoing executive loses influence over policy.
- Less experience: Unlike legislators who can serve many terms, executives have limited time to build expertise.
- Poorly designed policy: Limited time and experience can lead to rushed or underdeveloped policies.
You are not required to attach each advantage or disadvantage to a specific country. Still, being able to apply these ideas to course countries makes your arguments stronger.
How to Use This on the AP Comparative Government Exam
Free Response
Term limits work well for argument writing. A common setup asks whether executive term limits are an effective constraint on executive power, and asks you to connect your answer to a course concept such as a democratic regime, an authoritarian regime, or political legitimacy.
To write a strong response:
- Take a clear, defensible side instead of restating the prompt.
- Support your claim with specific evidence from course countries.
- Keep the same line of argument running through every example.
- Use any required course concept directly in your answer.
Comparison
When you compare countries, name the category first (does a limit exist, how long is it, has it been changed or removed), then explain why that difference matters for stability or policymaking. Avoid two common comparison mistakes: pointing out similarities or differences that are not relevant to the task, and claiming a shared trait that the countries do not actually share.
Common Trap
Do not assume a written term limit means power is actually limited. A country can keep the rule on paper while the office or the individual grows more powerful, so always check how the rule plays out in practice.
Sample Argument Setup
Prompt idea: Different countries have different rules on executive term limits. Are executive term limits an effective constraint on executive power? Address one of these concepts: a democratic regime, an authoritarian regime, or political legitimacy.
Sample claim and evidence:
A strong response could argue that term limits are not always an effective constraint, because they do not stop the office or an individual from gaining power over time. You can show this in both a democratic regime, such as Mexico, and an authoritarian regime, such as Russia.
In Mexico, presidents serve a single 6-year sexenio, and they have followed that limit throughout Mexican history. Even so, the power of the office has grown, seen in the president's ability to appoint and remove cabinet members and executive branch officials with little opposition.
In Russia, with a two consecutive term limit, Putin's power went largely unchecked. He shifted from president to prime minister and back, and the power of the office continued to grow.
Notice two things in that response. First, the same argument runs through both examples: even with term limits, executive power expanded. Second, the required concept (a democratic regime and an authoritarian regime) is built directly into the evidence.
Common Misconceptions
- "A term limit always limits real power." Not true. Rules can stay on paper while the executive or the individual still gains power, as the Mexico and Russia examples show.
- "Term limits are only good." They have real downsides, including lost experience, broken policy continuity, and lame-duck weakness.
- "Every course country has executive term limits." The UK has no formal limit on the prime minister, and China removed its presidential limit in 2018.
- "You must match each advantage and disadvantage to a specific country." You should know the advantages and disadvantages and be able to apply them, but you are not required to assign each one to a particular country.
- "More terms always means better government." Longer time in office can build experience, but it can also reduce accountability and concentrate power, which is exactly what term limits are designed to check.
