CSE Pro Topics by Subtest: What the CSC Scope Covers

The Civil Service Exam doesn't reinvent itself every sitting. The Civil Service Commission publishes the scope of each subtest in its exam announcement, and that scope has stayed the same across the 2026 sittings. That means you can know exactly which topic categories to prepare for before you open a single reviewer.

The trick is turning the official scope into a study plan. This guide breaks down the CSE Professional topics subtest by subtest — what the CSC lists, what each topic looks like in practice, and where to spend the bulk of your prep window.

How the CSE Pro Is Structured

The Professional exam has 150 multiple-choice test items plus a 20-item Examinee Descriptive Questionnaire (personal data, not scored content) — 170 items in all — in 3 hours and 10 minutes, pen-and-paper. The CSC lists four subtests:

Verbal Ability (English and Filipino) — word meaning, sentence completion, error recognition, sentence structure, paragraph organization, reading comprehension.
Numerical Ability — basic operations, number sequence, word problems.
Analytical Ability — word analogy, symbolic logic/abstract reasoning, identifying assumptions and drawing conclusions, data interpretation.
General Information — the Philippine Constitution, RA 6713 (Code of Conduct), peace and human rights issues and concepts, environment management and protection.

Clerical Ability is not on the Professional exam — it's a Subprofessional subtest. The CSC doesn't publish how many items each subtest has, and it doesn't publish a raw-score conversion. The pass mark is a general rating of at least 80.00.

Verbal Ability: What to Prepare

Verbal Ability rewards reviewers who've drilled useful vocabulary and grammar rather than the broadest word list. Remember it's tested in both English and Filipino.

Vocabulary Worth Knowing

Government and legal terminology — words like jurisdiction, plenary, concurrent, ratify, promulgate. Useful because they come up in government reading material.
Economic and financial vocabulary — fiscal, monetary, appropriation, disbursement, encumbrance. Public-sector budget language.
Latin and legal phrases — ad hoc, de facto, de jure, pro tempore, ex officio.
Connotation-heavy words — frugal vs stingy, diligent vs obsessive. Word-meaning items often reward fine-grained connotation.

Grammar and Sentence Items

Error recognition, sentence completion and sentence structure test the same core grammar: subject-verb agreement, tense consistency, pronoun reference, prepositions, and parallel structure. Paragraph organization asks you to put jumbled sentences in logical order — find the topic sentence first, then follow transition words.

Reading Comprehension

Expect formal, expository passages. If you read news editorials and government reports, you're already training for this. Practise identifying the main idea, the author's purpose, and what the passage does and doesn't say.

Numerical Ability: The High-Yield Topics

Numerical Ability is where preparation often matters most. Many adult reviewers haven't done arithmetic word problems in years, calculators aren't allowed, and word problems tend to follow familiar templates.

Word Problem Templates to Drill

Work problems — two workers, different rates, finishing together.
Distance problems — two vehicles meeting, catching up, passing. The classic d = rt setup.
Mixture problems — combining solutions of different concentrations.
Age problems — current age, future age, ratio of ages.
Percentage and discount problems — markup, markdown, successive discounts.
Ratio and proportion — direct, inverse, joint.

Number Sequence Patterns

Number sequence is named in the scope. Common patterns: arithmetic progression, geometric progression, alternating, double-step, prime-based. Drill all five until you can spot them quickly.

Basic Operations

Fractions, decimals, percentages, order of operations, and quick mental math. Word problems can also call on simple equations and basic geometry (perimeter, area), so be comfortable setting up and solving a linear equation. Trigonometry and calculus aren't in the scope — don't spend prep time on them.

Analytical Ability: Where Preparation Pays

Analytical Ability is usually the least familiar subtest, which makes it one where focused drilling can make a real difference.

Word Analogy

Name the relationship in the first pair (function, part-whole, degree, cause-effect, category, synonym or antonym), then find the option with the same relationship.

Symbolic Logic and Abstract Reasoning

Syllogism evaluation — classical syllogism patterns, with traps for affirming the consequent and denying the antecedent.
Letter, symbol and figure series — skip patterns, reversals, rotations.

Identifying Assumptions and Drawing Conclusions

Assumption identification — given a conclusion, identify the unstated assumption.
Inference questions — what conclusion can be drawn from the premises.
Strengthen/weaken arguments — which option, if true, weakens the argument.
Logical fallacies — ad hominem, appeal to authority, false dichotomy. Useful to recognise by example.

Data Interpretation

Tables, bar charts, line graphs. The challenge is reading speed under time pressure, without a calculator. Drill chart reading until you can pull specific values quickly, and estimate before you compute.

Ordering and seating puzzles aren't named in the CSC's scope, but they're good general reasoning practice if you have time. Draw a quick grid in your test booklet — the only place scratch work is allowed.

General Information: The Four Anchors

High-yield because the scope is short and predictable. See our full General Information guide.

Constitution Articles to Prioritise

Article II — Declaration of Principles. Especially Sections 1 (democratic and republican state; sovereignty in the people), 2 (renunciation of war), 3 (civilian supremacy).
Article III — Bill of Rights. Sections 1 (due process), 2 (search and seizure), 4 (free speech), 5 (religion), 14 (rights of the accused).
Article VI — The Legislative Department. Bicameral structure, qualifications, terms.
Article VII — The Executive Department. Powers of the President, qualifications, term.
Article VIII — The Judicial Department. Supreme Court structure, judicial review.
Article IX — Constitutional Commissions. Including the CSC itself.
Article XI — Accountability of Public Officers. Public office is a public trust; impeachment.

RA 6713 — Code of Conduct and Ethical Standards

Memorise the eight norms of conduct (commitment to public interest, professionalism, justness and sincerity, political neutrality, responsiveness to the public, nationalism and patriotism, commitment to democracy, simple living). Memorise the prohibited acts (financial and material interests, outside employment, disclosure of confidential information, solicitation of gifts).

Peace and Human Rights

The Universal Declaration of Human Rights, the major human rights treaties the Philippines has ratified, the peace process agreements, and the Indigenous Peoples' Rights Act (RA 8371).

Environment Management and Protection

RA 9003 (Ecological Solid Waste Management Act), RA 9275 (Clean Water Act), RA 8749 (Clean Air Act) and RA 9729 (Climate Change Act).

Philippine history and current events aren't in the CSC's current General Information scope. Don't spend your limited hours there.

What Stays the Same Between Sittings

The Scope

The CSC's announcements for the March and August 2026 sittings listed the same four Professional subtests and the same topics within each. The CSC issues a new announcement for each sitting, so check the one for your sitting — for 14 March 2027, it's due around mid-October 2026.

Memorisation Topics Are Stable

The Constitution and RA 6713 don't change often. Learn them thoroughly once and the knowledge carries over to any sitting.

Pro vs Sub: Topic Differences

Pro includes Analytical Ability; Sub replaces it with Clerical Ability (filing and spelling). Verbal Ability, Numerical Ability and General Information have the same listed scope on both.

If you're choosing between levels, see CSE Pro vs Sub. Pro gives second-level eligibility and opens more positions. Sub gives first-level eligibility for clerical government roles.

How to Use This Topic Map

Don't drill every topic equally. A sensible split for most Pro reviewers:

About 30% on Numerical Ability — word problems and number sequences reward focused practice.
About 30% on Analytical Ability — analogy, syllogisms, assumptions and data interpretation.
About 25% on Verbal Ability — vocabulary, grammar and reading comprehension.
About 15% on General Information — Constitution, RA 6713, peace and human rights, environment.

Shift the split toward whichever subtest your practice results show is weakest. If you're working with a fixed 30-minute daily window, see the 12-week 30-minute plan for the daily structure.

FAQ

Does the CSC publish official topic weights?

No. The CSC publishes the scope of each subtest and the total number of items, but not item counts or weights per subtest or topic. Any exact split you see online is unofficial.

How often does the topic mix change?

The scope was the same across the 2026 announcements. Each sitting gets its own announcement, so check the current one for any changes.

Should I memorise the entire 1987 Constitution?

No. Prioritise Articles II, III, VI, VII, VIII, IX and XI, then skim the rest.

Do I need to study current events?

Current events aren't in the CSC's current General Information scope. Focus on the four listed areas.

Is Clerical Ability on the Pro exam?

No. Clerical Ability (filing and spelling) is on the Subprofessional exam only.
