API 1169 study guide: what to memorise, what to look up, what to strike
This API 1169 study guide sorts the exam by how its questions use the material: 5 Body of Knowledge categories with no published weights, and a reading list set by the effectivity sheet for exams from December 2026 to August 2027 (API, checked October 2026). Six closed-book publications go in your head; the regulations appear on screen, so you learn their layout instead.

What the exam covers: five categories, estimated shares
The exam is built on five main categories: inspection and management knowledge areas, front-end construction, installation construction, back-end construction and post-construction; at least one question comes from each, and API publishes no weights. That last clause is why every share on this page carries the word estimated. Earlier editions of the Body of Knowledge printed a percentage per category; the current one prints none, so the ranges below are our estimate, built from how much each section lists and how deep it goes. Use them to rank your study hours, not to forecast a score.
- 1. Inspection & management35–45%
- 2. Front-end construction8–12%
- 3. Installation construction25–36%
- 4. Back-end construction15–22%
- 5. Post-construction3–10%
The table adds what the donut cannot show: the first option you can strike in each category, before you have finished reading the stem. The sub-topics of each category are on the cards in the next band.
| Category | Est. share | First strike |
|---|---|---|
| 1. Inspection & management | 35–45% | Any option where the inspector does the contractor's work, directs the crew or signs off money |
| 2. Front-end construction | 8–12% | Digging on old, faded or missing locate marks because the schedule is tight |
| 3. Installation construction | 25–36% | The value from the other Part: a gas number offered in a liquid stem, or the reverse |
| 4. Back-end construction | 15–22% | A step out of order: backfill before the coating check, a repair made while the section is under pressure |
| 5. Post-construction | 3–10% | Closing a tract on a verbal OK when the line list asks for a signed condition |
Five category guides, two written so far
Each card is one Body of Knowledge category with the sub-topics it covers. Two have a depth guide now: safety, quality and environmental inspection and welding, coating and installation construction. By our estimate those two hold 60 to 81 percent of the exam between them, which is why they came first.

Refs
What you memorise and what you read on screen
The reference rule decides how you study each document. API's rule: the exam is closed book (no personal notes or books), with the listed parts of 49 CFR 192 and 195, 29 CFR 1910 and 1926, 50 CFR 21 Subpart B and the FERC Wetland and Waterbody Procedures (May 2013), or the Canadian equivalents, shown as on-screen PDFs without Ctrl+F search; a calculator and scratch paper are provided. So you learn the regulations as a map and everything else by heart.
The closed-book set on the current sheet is API RP 1169 (2nd ed., 2020), API RP 1110 (7th ed., 2022, appendices excluded), API Spec Q1 (10th ed., Sections 3 to 5), CGA Best Practices, INGAA CS-S-9 Pressure Testing Safety Guidelines (2018), and either API Std 1104 (22nd ed., Sections 3 to 11) or CSA Z662:23 (listed chapters), per API as of October 2026. Check it against the API 1169 effectivity sheet (PDF) before you buy or borrow a single book.

The effectivity sheet, and what changed this cycle
The effectivity sheet is API's list of the publications and editions that questions are written from, issued for a run of testing windows. The current one is the effectivity sheet for exams from December 2026 to August 2027, per API as of October 2026; read it at the API 1169 effectivity sheet (PDF). A question is built on the edition named there, so a borrowed copy one edition back can teach you a clause that has since moved or changed.
Against the previous sheet, the list is the same publication for publication. The one difference is a quality-system detail: API Spec Q1 now names its Addendum 2 among the parts in force. RP 1169, RP 1110, CS-S-9 and the welding standards hold their editions, and ASME B31 is still absent.
One gap to watch: the December 2027 window falls after the period this sheet covers. If that is your window, check whether API has issued the next effectivity sheet before you buy or borrow editions for it.
Study the edition on the sheet, not the edition on your shelf.
Three documents are on the sheet only in part, and each one is a trap for a study source that covers the whole book:
- API Spec Q1: Sections 3 to 5 only, which is where the terms and the quality-system requirements an inspector meets in the field sit: records, calibration, traceability, nonconformance, change control. A course that drills the rest of Q1 is teaching outside the sheet.
- API RP 1110: the body of the document, without its appendices.
- API Std 1104: Sections 3 to 11. If you choose CSA Z662 instead, only the chapters the sheet lists count.

Method
Read the four options first: they name the document
Read the answers before the stem. On this exam the four options tell you which book the question comes from, and that tells you whether to reach for the on-screen PDF or for what you memorised. Reading the stem first usually means reading it twice: once to understand it, once after the options show you what it was really asking.
| When the options are… | The question lives in | Strike first |
|---|---|---|
| Four numbers in the same unit | An on-screen lookup in Part 192, 195 or the OSHA parts | The value that is right for the other Part or the other trigger |
| Four inspector actions | RP 1169 Section 4 and the Annex A chapter for that activity | Actions that perform the work, direct the crew, approve cost or redesign |
| Four document names | RP 1169 records and API Spec Q1 terms | A real document from a different phase, such as an alignment sheet where the line list belongs |
| Four steps or orders | The Annex A sequence, the CS-S-9 test steps, the escalation ladder | The option that puts a later step first |
After the first strike you are usually down to two options that differ by one modifier: gas against hazardous liquid, before against at lowering-in, 4 ft against 5 ft in a trench, a tolerance zone of 18 in each side of the facility against a clearance of 12 in. That single word or digit is the question. Find it, check it in the document the options pointed to, and stop.
An eight-week plan, counted back from your window
Anyone applying now sits a 2027 window. The windows are April 9 to 30, 2027 (apply by February 4); August 6 to 27, 2027 (apply by June 4); December 3 to 24, 2027 (apply by September 30), per API as of October 2026; confirm them at API ICP: schedules and fees. Count eight weeks back from the first day of your window to get a start date. In every 2027 window the application deadline lands shortly before that start date, so file first and study second. Fees, moves and late applications are on the dates and fees page.
The plan follows the construction order in Annex A of RP 1169, which gives every week a place on the right-of-way instead of a chapter number.
Week 1: the inspector's job
RP 1169 Section 4 end to end: authority, code of conduct, quality, deficiencies against nonconformances, records, qualifications, calibration. Then API Spec Q1 Sections 3 to 5. This is the largest category and the reasoning every other week leans on.
Week 2: safety and environment, by map
Walk the listed OSHA parts and the FERC Wetland and Waterbody Procedures as on-screen documents: note where excavation, confined space, fall protection, waterbody classes and workspace setbacks sit. Add CS-S-9 for pressure-testing safety.
Week 3: front-end construction
The first Annex A chapters in order: survey and staking, then clearing and grading. Pair them with CGA Best Practices on one-call, locate colours and hand exposure inside the tolerance zone.
Week 4: stringing, bending, ditching
Pipe handling and the pipe tally, field bends, ditch depth and clearance. Read Part 192 and Part 195 side by side here: this is where the gas-against-liquid swaps live.
Week 5: welding and NDE
Your chosen welding standard, API 1104 Sections 3 to 11 or the CSA Z662 chapters, plus the welding sections of 192 and 195: qualification, inspection percentages, repairs and cut-outs.
Week 6: coating to backfill
Field joint coating and holiday detection, lowering-in, HDD installation, backfill and cathodic protection, in the order Annex A runs them. Most sequence questions come from this stretch of the line.
Week 7: testing and close-out
RP 1110 and the test sections of 192 and 195: pressure, hold time, records. Then clean-up and restoration, line markers, the line list, the punch list and turnover.
Week 8: drill and review
No new reading. Work full practice sets, and file every miss by its distractor pattern (wrong Part, wrong party, wrong order, wrong document) rather than by topic. The pattern you miss most is next morning's review.
The plan in four lines
- Category 1 first: its role rules decide scenario questions everywhere else.
- Closed-book documents get memory; on-screen regulations get a map.
- Study only the parts the effectivity sheet lists, in the editions it lists.
- Log each miss under its distractor pattern.

Course
Self-study, classroom training or an online course
No course is required. API sets eligibility by documented work experience, not by training hours (API 1169 program page), so a class is a study choice; the application never asks for one. The three routes differ in structure, and the exam asks the same of all of them.
| Route | What you get | Fits you if | Check before paying |
|---|---|---|---|
| Self-study | The listed publications, the free Body of Knowledge and effectivity sheet, practice questions | You read standards at work and can hold a schedule alone | That you have the editions the sheet names |
| Classroom training | Several days with an instructor walking RP 1169 and the regulations, a fixed date | You learn faster against a deadline, with questions answered live | That the course was updated to the current sheet |
| Online course | Live or recorded lessons, question banks, your own timing | You work rotations or travel between spreads | Whether its questions are built on current editions and explain every option |
Twelve questions from the three categories still waiting for a guide
Four questions each from front-end construction, back-end construction and post-construction. Use the chips to work one category at a time. Before you pick, strike two options with the toggle beside them, then decide between the survivors. For a full mixed set across all five categories, go to the free practice test.
Press × to strike an answer you have ruled out, then pick from what is left. Keys: A–D or 1–4 pick, Shift+1–4 strikes. The verdict, the reasoning and a note on every option open in place.

FAQ
Questions people ask
What is on the API 1169 exam?
115 multiple-choice questions, of which 100 are scored and 15 are unscored pretest items, in 3 hours. They come from five main categories. By our estimate inspection and management knowledge is the largest category and post-construction the smallest.
What is the API 1169 effectivity sheet?
API's list of the publications, editions and sections that questions are written from for a run of testing windows. The current one is the effectivity sheet for exams from December 2026 to August 2027, per API as of October 2026: API 1169 effectivity sheet (PDF).
Do I need API 1104 or CSA Z662?
One of them, not both. The sheet lets you study API Std 1104 Sections 3 to 11 or the listed CSA Z662 chapters, and the questions target content the two share. Choose the one that matches the codes you work under.
Is there a free API 1169 study guide?
Yes. API publishes the Body of Knowledge and the effectivity sheet as free PDFs, and this page maps both. The closed-book publications themselves are copyrighted documents you get from their publishers or your employer's library.
Is there an API 1169 examination guidebook, and do I need it?
Third-party guidebooks and question books exist; none is required. Treat one as a secondary source: check that it was written for the editions on the current sheet, and drop it if it promises real exam questions or a pass rate.
Do I need a course to pass API 1169?
No. Eligibility rests on documented work experience, and the exam tests the publications themselves. A course helps if you want structure or a fixed date; it adds nothing the effectivity sheet does not already list.
Which API certification is best?
The one that matches the work. API 1169 covers new pipeline construction on the right-of-way; API 1184 covers facility construction such as stations and terminals; API 510, 570 and 653 cover in-service pressure vessels, piping and tanks. Welding-only roles often look at AWS CWI instead.
