D1.1 Training and Exam UPDATES:
D1.1 Exam – Code Edition Guidance
- Effective August 1, 2025, candidates may use either the 2020 or 2025 edition of the D1.1 code when taking the exam.
- All exam questions are designed to be answerable using either edition, so candidates will not be disadvantaged based on the version they study from.
Code Edition Recommendations by Exam Date:
- Before August 1, 2025 (Prometric): Candidates should study the 2020 edition.
- Between August 1 and December 31, 2025 (Prometric): Candidates may study either the 2020 or 2025 edition.
- Note: Starting October 1, AWS Seminars will begin using the 2025 edition for instruction, though the 2020 edition remains valid for the exam through December 31.
- After December 31, 2025 (Prometric): Candidates must study the 2025 edition.
Important:
It is recommended that candidates testing toward the end of 2025 use the 2025 edition of the D1.1 Codebook. This will help ensure a smoother transition in the event of a retest in 2026, when only the 2025 edition will be accepted.
