What Is the Specialized Test, and Do You Have to Take It?

The Specialized Test (Senmon Shiken) is the part of the First Stage that tests subject knowledge specific to the division you apply to, sat alongside the Basic Ability Test that every candidate takes regardless of division. Where the Basic Ability Test is identical for everyone, the Specialized Test differs entirely depending on whether you chose the Administrative division, one of the Technical divisions, or the Education division, since each is built around the knowledge that role actually needs.

What does the Administrative division’s Specialized Test cover?

Administrative-division candidates are tested on the subject knowledge that supports policy administration and legal work: constitutional and administrative law, civil law, economics, and related social-science subjects appear across the multiple-choice questions in this section. It rewards genuine familiarity with legal and economic reasoning built up over a course of study, which is why administrative law and micro and macroeconomics tend to be treated as the highest-priority subjects by candidates preparing for this division, since they carry more weight in the question set than peripheral topics.

What does a Technical division’s Specialized Test cover?

Technical divisions are tested on the engineering or scientific subject matter tied to that specific field, whether that is civil engineering, mechanical engineering, chemistry, agriculture or another technical area the National Personnel Authority runs a division for. If you studied a technical field at university, this test is largely an extension of your coursework rather than new material, which is a real advantage over Administrative-division candidates who are often building legal and economic knowledge from a more general starting point. Confirm exactly which technical divisions are open in the current cycle against that year’s juken annai, since the divisions on offer can change.

Does everyone have to sit a Specialized Test?

Yes, in the sense that every division of the General Service exam includes some form of specialized subject content matched to that division, though what counts as “specialized” naturally differs by field. There is no version of the exam where a candidate sits only the Basic Ability Test and skips subject-specific content entirely, which is a meaningful difference from some local government exams that do offer a knowledge-only track. If choosing between divisions is itself the harder decision, how to choose between the Administrative, Technical and Education divisions walks through that choice directly.

How is it weighted against the Basic Ability Test?

Both the Basic Ability Test and the Specialized Test feed into one combined First Stage result, along with the General Essay Test for Administrative-division candidates, rather than being scored and passed as fully separate hurdles. Because the Specialized Test typically has more total questions than the 30-question Basic Ability Test, and tests knowledge that is harder to build quickly through pattern practice alone, many candidates preparing without a prep school treat it as the section that needs the earliest and most sustained study time, a point covered further in whether self-study is realistic for this exam.

Can you change which division’s Specialized Test you sit?

Division choice is made at the time of application, and the specific process and any restrictions on switching are set out in the current cycle’s juken annai, so this needs checking directly against that year’s official guide rather than assumed from a past cycle’s rules. Since the Specialized Test content is division-specific, switching divisions after you have already started studying one subject area is a real cost worth factoring in before you apply, not just an administrative formality.

What happens after the Specialized Test?

Clearing the First Stage, meaning a combined result across the Basic Ability Test, the Specialized Test and, for the Administrative division, the essay, moves you to the Second Stage personal interview. Passing both stages puts you on that year’s passer list, but the actual hiring decision still comes through kancho homon, the ministry-visit process covered in what kancho homon actually involves.

Frequently asked questions

Is the Specialized Test harder than the Basic Ability Test? It tests a different kind of preparation rather than being simply harder: it rewards built-up subject knowledge, whereas the Basic Ability Test rewards structured reasoning technique that improves quickly with practice.

Can I study for the Specialized Test without having studied that subject at university? It is more difficult but not impossible, particularly for the Administrative division’s law and economics content, since candidates from unrelated fields do pass every cycle with dedicated study; the Technical divisions are harder to approach without relevant coursework.

Does the Specialized Test have a separately published passing score? No, it combines with the Basic Ability Test and, where applicable, the essay into one First Stage result, so there is no standalone published cutoff for the Specialized Test alone.

Is the content the same every year? The subject areas per division have been stable, but always confirm the current cycle’s exact scope against that year’s juken annai before relying on a past year’s syllabus.

Do Education division candidates sit a Specialized Test too? Yes, the Education division, added to the exam in 2025, has its own specialized content matched to that field, distinct from the Administrative and Technical divisions.
