There Is No Fixed Testing Calendar to Chase
Many certification articles about "exam dates" list application deadlines and fixed windows. For the AWS Certified Data Engineer - Associate (DEA-C01), the sources we reviewed do not publish a seasonal testing-window calendar or a registration deadline tied to a cohort. Delivery runs through Pearson VUE, which means you choose an available appointment at a test center or through online proctoring. Your "exam date" is the slot you book, and the real planning questions are about timing: which exam guide version you are preparing against, when your preparation will be ready, and what you need to decide before you pay.
This article treats scheduling as a preparation problem. It covers what the booking involves, what is known and unknown about the current exam version, how to pick a delivery route, and how to align a target date with the four DEA-C01 content domains. For the broader picture of what the credential is, see What Is DEA-C01 Certification? and the overview at DEA-C01 Certification.
What You Are Actually Booking
Before you pick a date, know what that date buys you. These are the confirmed mechanics for this exam:
| Item | DEA-C01 detail |
|---|---|
| Credential | AWS Certified Data Engineer - Associate (DEA-C01) |
| Testing provider | Pearson VUE, test center or online proctoring |
| Fee | USD 150, plus applicable taxes under AWS testing policies |
| Discount benefit | An active AWS Certification gives a 50% discount for a next exam; not an unrestricted member discount |
| Questions | 65 total: 50 scored, 15 unscored (unscored items are not identified) |
| Time | 130 minutes |
| Item types | Multiple-choice and multiple-response |
| Passing score | Minimum scaled score of 720 on a 100-1,000 scale |
| Languages listed | English, Japanese, Korean, Simplified Chinese |
| Validity | Three years |
Two points deserve emphasis. First, there is no published member and non-member price split for this credential, so you should expect a single USD 150 fee before taxes. For a fuller accounting, see DEA-C01 Certification Cost 2026: Complete Pricing Breakdown. Second, the 720 passing figure is a scaled score, not a 72% raw-score threshold. A percentage on a practice test cannot be converted into the official scaled score, so avoid choosing your exam date based on hitting a particular practice percentage. The details are in DEA-C01 Passing Score 2026: Exactly What You Need to Pass.
Scoring is compensatory across the whole exam. There is no separate pass requirement for each domain, unanswered items count as incorrect, and there is no penalty for guessing. That affects scheduling indirectly: because a weak domain can be offset by strong ones, you do not need to delay your date until every domain feels equally polished, but you should not gamble on skipping a heavily weighted one.
Exam Guide v1.1 and the Question of Timing
The version you prepare against matters more than the calendar month. The latest revision in the retrieved revision record is DEA-C01 Exam Guide v1.1, published December 12, 2025. The sources we reviewed list no newer revision and establish no separate, precise effective or go-live date. Do not assume the exam content changed on any particular day by adding a month to the publication date; that inference is not supported.
The practical advice is to anchor your preparation to the current published guide and its linked domain and service pages, then re-check them shortly before your appointment. The guide states that its content lists are not exhaustive and that service lists are subject to change, so a re-read in the final week is cheap insurance.

Choosing Between a Test Center and Online Proctoring
Because Pearson VUE offers both routes, your scheduling decision is partly a delivery decision. The exam has no scheduled breaks, and the two routes handle that differently. At a test center, unscheduled breaks are possible but consume your exam time. With online proctoring, you cannot leave camera view for an unapproved break. With 130 minutes for 65 questions, you have roughly two minutes per question on average, so every minute spent away from the clock matters.
- Choose a test center if you want a controlled environment, an unreliable home connection or workspace would worry you, or you want clear separation from household interruptions.
- Choose online proctoring if travel is the main barrier and you can guarantee a quiet space and a camera setup that satisfies the proctoring rules.
Details such as calculator availability, book policy, and adaptive-testing behavior were not established in the passages we reviewed, so do not rely on assumptions about them. Check the AWS During Testing policies and your Pearson VUE confirmation before test day. Schedule your appointment early enough that you can resolve any system-check or ID questions without pressure.
Accommodations and Languages: Decide Before You Book
Two items must be settled before you click "schedule," not after.
The ESL +30-minute accommodation
Eligible candidates may use an ESL +30-minute accommodation, but it must be requested before booking. It is not silently added to the standard 130-minute timer. If you think you qualify, make the request first, wait for approval, and only then choose your date. Booking first and asking later is the sequence to avoid.
Language choice
The exam lists English, Japanese, Korean, and Simplified Chinese. Pick the language you read technical material in most comfortably, since DEA-C01 scenario questions contain dense service terminology. Confirm availability for your chosen delivery route when you schedule.
Eligibility basics
There is no required prior certification, degree, mandatory course, or prescribed work-hour total. The target-candidate recommendation of two to three years in data engineering or data architecture and one to two years using AWS is guidance, not an admission rule. The general minimum age is 13, with parent or guardian consent required for ages 13-17 under AWS policy. A fuller explanation is in DEA-C01 Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Working Backward From a Date by Domain Weight
This is the one planning section in the article, and it is tied to the exam's weights rather than a generic template. The four domains and weights are: Data Ingestion and Transformation (34%), Data Store Management (26%), Data Operations and Support (22%), and Data Security and Governance (18%). Because ingestion and transformation is the largest scored domain, it deserves the earliest and longest block. The guide does not publish sub-domain percentages, so do not assign your own.
Data Ingestion and Transformation
- Task 1.1: streaming versus batch reads, schedulers, event triggers, throttling, fan-in/fan-out, replayability
- Task 1.2: format conversion such as .csv to Apache Parquet, transformation with Glue, EMR, Lambda, Redshift
- Task 1.3: orchestration with Step Functions, MWAA, Glue workflows; alerts with SNS and SQS
- Task 1.4: Lambda concurrency, IaC with CloudFormation and CDK, SAM packaging, CI/CD concepts
Data Store Management
- Task 2.1: matching Redshift, DynamoDB, RDS, MemoryDB, and Aurora PostgreSQL to access patterns; Apache Iceberg; vector index types HNSW and IVF
- Task 2.2 and 2.3: Glue Data Catalog, crawlers, partition sync, S3 Lifecycle, versioning, DynamoDB TTL
- Task 2.4: schema design, lineage, partitioning, compression, vectorization concepts
Data Operations and Support
- Task 3.1 and 3.2: automating with Lambda and EventBridge, Athena queries, DataBrew, visualization
- Task 3.3: CloudTrail, CloudWatch Logs, log analysis with Athena and OpenSearch Service
- Task 3.4: data quality rules, sampling, skew
Data Security and Governance, then review
- Tasks 4.1 to 4.3: IAM, Secrets Manager, Lake Formation permissions, KMS, cross-account encryption, masking
- Tasks 4.4 and 4.5: CloudTrail Lake, Macie, Config, Region and sovereignty controls
- Final days: re-read the live guide and service lists for changes
You can compress or stretch this to match your own experience. A candidate with daily Glue and Redshift work may move quickly through Domain 1 and spend more time on governance topics, while someone newer to AWS may need extra time on Domain 2's store-selection tradeoffs. The point is to set your appointment after you have placed each domain on the calendar, not before. For a deeper plan, see DEA-C01 Study Guide 2026: How to Pass on Your First Attempt, and for a realistic sense of effort, How Hard Is the DEA-C01 Exam? Complete Difficulty Guide 2026.
Key Takeaway
Book a date only when you can point to a calendar slot for each of the four domains, with the largest block reserved for Data Ingestion and Transformation. If your date arrives before Domain 1 is covered, move the date rather than the domain.
Scope Items to Verify Before Your Date
A few details in the published materials are inconsistent or evolving. They are worth a final check shortly before your appointment, because the guide itself says its lists are not exhaustive and may change.
Items worth a last-week check
These are observations from the published materials, not resolved rulings.
- AWS SCT: The v1.1 revision record removes AWS Schema Conversion Tool from the in-scope service list, yet Skill 2.4.3 still names AWS SCT alongside AWS DMS Schema Conversion. Both observations exist. Learn DMS Schema Conversion well, and treat SCT as unresolved rather than assuming it is in or out.
- Quick versus QuickSight: The service inventory says Amazon Quick, while Skills 3.2.1 and 3.2.2 say QuickSight. Both labels are published; do not assume they are interchangeable without checking.
- Newer topics: LLM integration in processing (Skill 1.2.10), vector index types (Skill 2.1.8), Apache Iceberg (Skill 2.1.7), SageMaker Catalog, and SageMaker Unified Studio domains, domain units, and projects (Skill 4.1.7) all appear in the skill lists. They stay within data-engineering scope; machine-learning model training and inference are explicitly out of scope.
Also note what is out of scope: programming-language-specific syntax and drawing business conclusions from data are excluded job tasks. Skill 1.4.3 names languages such as Python, SQL, Scala, R, Java, Bash, and PowerShell, but that does not make the exam a syntax test. For a fast memory aid close to your date, the DEA-C01 Cheat Sheet 2026: One-Page Review of Must-Know Facts is a useful companion, and the main practice site at DEA-C01 Exam Prep offers knowledge practice to test your recall.
Your Certification Clock After You Pass
Scheduling does not end at your first attempt. The credential is valid for three years, and the renewed period runs from completion of the recertification action, not from the previous expiry date. According to the AWS credential page, renewal is done by passing the latest version of this exam. The AWS recertification table additionally permits passing AWS Certified Generative AI Developer - Professional to renew an active Data Engineer Associate certification for three years.
The Data Engineer Associate row does not list a CEU or CPE quota or a Skill Builder maintenance route, so do not assume options available to other certifications apply here. Plan your renewal exam the way you planned the first one: confirm the current guide version and re-map your preparation to the domains.
If you are weighing whether the investment is worthwhile at all, the articles on whether the DEA-C01 certification is worth it and the DEA-C01 salary guide discuss how to evaluate the evidence. No issuer pass rate or credential-specific salary premium was found in the reviewed sources, so be cautious of any page that quotes one; see DEA-C01 Pass Rate 2026: What the Data Shows.
