Free Practice Questions for AWS D1.1 Endorsement

Current AWS CWIs and SCWIs can take the D1.1 endorsement exam. A candidate seeking CWI certification can also take it as the initial Part C codebook exam. The endorsement stays valid as long as the CWI certification remains active and is renewed on schedule.

Yes. AWS provides an electronic PDF copy of D1.1/D1.1M:2025 on the Prometric workstation, with the word search function disabled, and you may bring your own original or permanently bound printed copy. Questions are based on the 2025 edition, so using any other edition is at your own risk.

The English exam has 50 scored multiple-choice questions plus 5 unscored pretest items. You get 135 minutes to answer questions within a 150-minute appointment at a Prometric test center; the language-assisted version allows 120 minutes. That is about 2.5 minutes per item.

You must achieve a minimum overall score of 72% to pass the D1.1 Endorsement. This matches the 72% threshold used across CWI Parts A, B, and C and the other CWI endorsements. There is no separate domain pass; the 72% applies to the total scored items.

The 2026 AWS price list (effective January 1, 2026) lists the D1.1 Endorsement at $445 for AWS members and $540 for non-members, paid to AWS at registration in the United States and Canada. Re-examination follows AWS QC1:2016-AMD1; check the current price list for the retest fee.

Clause 5 lets you write a WPS without testing IF every variable falls inside the prequalified limits (approved processes, base metals from Table 5.6, matching filler metal, prequalified joint details, preheat from Table 5.11, etc.). Clause 6 is the path you must follow when any variable falls outside Clause 5 - you weld a test coupon, run mechanical tests, and document the result on a PQR. The endorsement frequently tests this boundary, so memorize the Clause 5 limits cold.
