How to prepare for SKB CPNS begins the moment your name enters the top three times the number of positions after SKD. Read the field syllabus your agency publishes, calculate the score gap against rivals in the SKD ranking, then drill field questions and the extra test types used. SKB carries 60 percent of the final score, so the SKD ranking can still flip here.
- SKB carries 60 percent and SKD 40 percent in deciding the final passing rank
- SKB participants are the top three times the number of positions who cleared the SKD passing grade
- SKB material is specific to the job field, unlike the general SKD
- The field syllabus that matches the position you applied for
- Your SKD score to calculate the margin you must close during SKB
- SKB CAT question banks and practice for your agency's test types
Key SKB Numbers That Shape Your Odds
What SKB Is and Why It Differs from SKD
SKB, or the Field Competency Selection, is the second stage of CPNS selection that tests your command of a specific job field. The earlier SKD measured general ground through TWK, TIU, and TKP for every applicant. SKB shifts to material tied to the position, for example health for nursing candidates, pedagogy for teaching candidates, or law for legal analyst candidates. Each agency publishes its own syllabus, so the questions you face differ from applicants in other positions. The next core difference lies in scoring. SKD relies on a passing grade you must clear, while SKB recognizes no separate passing threshold. The SKB score is then combined with SKD in an integration system, and those who advance to the final stage are the participants with the highest combined score up to the number of positions. The 60 percent SKB weight lets this stage reorder the ranking formed by the SKD results.
SKD and SKB Compared at a Glance
| Aspect | SKD | SKB |
|---|---|---|
| Material focus | General: TWK, TIU, TKP | Specific to the job field |
| Final score weight | 40 percent | 60 percent |
| Passing grade | Yes, per subtest | None, ranking based |
| Syllabus source | Uniform nationally | Published by each agency |
Because its weight is larger, SKB deserves intensive practice even though it often sits only weeks after SKD.
6 Steps to Prepare for SKB CPNS After Passing SKD
The gap between the SKD announcement and the SKB test is usually 3 to 6 weeks. This framework arranges that short window around whatever raises your odds the most.
- 1
Read the field syllabus from your agency, do not guess the material
The first step most participants skip is reading the official announcement from the agency running your position. Each agency publishes its own SKB syllabus, and its scope is bound to the job you applied for. Teaching candidates face pedagogy and subject material, nursing candidates face clinical nursing material, auditor candidates face public sector accounting and audit material. Guessing the material from someone else's experience risks missing the mark because the syllabus can change each year. Download the official announcement from the agency site and the SSCASN portal, mark every topic mentioned, then build a list of what will truly be tested before opening a single question.
Tips- Keep the agency's official announcement in one folder for easy reference
- Match the syllabus against the job description so you know the depth expected
- 2
Calculate your SKD ranking position and the margin to close
Once SKD scores are announced, you can estimate your position among participants advancing to SKB for the same slot. SKB participants number three times the quota, so a position with 5 slots has about 15 people competing at SKB. Because the SKB weight reaches 60 percent, participants whose SKD score lagged still have room to overtake through a strong SKB. Conversely, a slim SKD lead guarantees nothing. Convert your SKD score to its 40 percent weight, compare it against likely rivals, then set how high an SKB score you need to feel safe.
Tips- Treat the SKD score as starting capital, the SKB number will decide the final order
- Do not settle into a high SKD rank, recompute once the 40 to 60 weighting applies
A first place in SKD can slip if a rival with a lower SKD performs far stronger in the 60 percent weighted SKB. - 3
Master the core field material through targeted question drills
SKB CAT is the largest component, at least 50 percent of the SKB score at central agencies and at least 60 percent at regional ones. That makes field mastery the top priority. Split the syllabus into daily topics, then study each topic while working its questions right away so understanding stays measurable. Focus your energy on the topics that appear most often and sit closest to the daily duties of the job. If you applied for a position aligned with your education, this stage feels like revisiting coursework in a public service context. If your position stretches a little from your major, set aside extra time for the least familiar topics.
Tips- Work questions topic by topic first, then mixed sets, so you recognize each material pattern
- Note every concept you got wrong on one sheet for quick review before test day

Learn which extra tests your agency uses
Beyond CAT, agencies may add other tests to suit the job, with a cumulative share of at most 50 percent of the SKB score at central agencies. The forms vary: psychological tests to gauge emotional stability and maturity, an interview with a small weight probing motivation and integrity, work practice tests for technical positions, physical fitness or endurance tests for certain posts, and foreign language tests when the job requires them. Central agencies usually cap the extras at three types. Read the announcement to confirm which tests apply to your position, then prepare each component separately. Preparing only for CAT while ignoring the interview or practical test leaves part of the score wasted.
Tips- For interviews, prepare concrete stories about teamwork and problem solving
- For practical tests, drill the core technical skill of the job until it runs smoothly and precisely
- 5
Run timed simulations in conditions like the real exam
Material held in your head needs testing in conditions that resemble the exam room. Run a timed SKB CAT simulation on a computer, with a question count and duration close to your agency's rules. A simulation trains two things at once: the speed of parsing field questions and the calm of facing a screen counting down. After each simulation, dissect the wrong answers and group them by topic so you know which material is still fragile. If your agency uses an interview or practical test, run a separate simulation for that component, for example answering interview questions in front of a mirror or recording yourself to judge the clarity of your answers.
Tips- Repeat the simulation at least twice a week at a time close to the real schedule
- Save each simulation score so you see the trend of progress, not a one-off result
- 6
Tidy your documents and guard your condition before test day
The final week goes to firming up the technical side and guarding your body. Make sure the exam card is printed, the test location is confirmed, and the schedule for each SKB component is recorded neatly, especially when the CAT, psychological, and interview tests fall on different days. Cut down on adding heavy new material, and swap it for reviewing your error notes and stabilizing what you already understand. Enough sleep the night before matters as much as practice, since field questions demand full concentration. Arrive early at the location to avoid the rush that can disturb your focus in the first minutes.
Tips- Make a list of items to bring the day before so no document is left behind
- When SKB components span different days, save dedicated energy for each schedule
An administrative slip such as a wrong location or missing document can sink you even when the material is mastered.
The Range of Test Types Within SKB
SKB CAT
A computer based test from BKN covering job field material. Its share is the largest, at least 50 percent of the SKB score at central agencies.
Psychological Test
Gauges emotional stability, maturity of attitude, and how well the personality fits the demands of the applied position.
Interview
Explores motivation, integrity, and awareness. Its weight is small, usually at most 10 percent, and it plays a complementary role.
Work Practice Test
Tests technical skill directly for positions that demand field ability or specific expertise.
Fitness Test
Measures physical fitness and endurance for positions whose duties require a certain stamina.
Foreign Language Test
Applied when the position demands foreign language ability in daily work.
“Many participants think passing SKD means the work is nearly done, when SKB is exactly where the map can change entirely. We often coach participants whose SKD score sat in the middle, then overtook because their field material was far more mature. The key is reading the agency syllabus from day one, then drilling the right field questions instead of the general material already finished at SKD.”
