2.1 JTA as the Exam Blueprint
Key Takeaways
- ACI's Job Task Analysis identifies knowledge and skills that may be included on the written and performance examinations.
- The JTA separates general concepts from specific procedures, values, and performance tasks.
- Candidates should convert each JTA line into a study action, practice action, or self-check.
- The JTA keeps preparation focused on the seven required standards instead of broad concrete trivia.
Turning the JTA Into a Study Map
The ACI Job Task Analysis, or JTA, is the practical blueprint for Concrete Field Testing Technician Grade I preparation. It lists the knowledge and skills that may be included on the written and performance examinations. ACI urges candidates to use the JTA to prepare, and ACI policy ties examination content to that analysis.
The JTA is useful because it separates different kinds of readiness. Some lines ask candidates to understand scope, significance, equipment, or general concepts. Other lines point to specific procedures, values, timing requirements, or reporting duties. The performance side asks candidates to perform or verbally describe tasks where allowed.
Do not read the JTA as a passive document. Convert it into a working checklist. For each bullet, ask whether you can explain it without notes, identify where it appears during the method, perform it with equipment, and record the result when required. If the answer is no, that line becomes a study task.
| JTA wording type | Candidate action |
|---|---|
| Understand scope and significance | Explain why the method is used and what it does not cover |
| Know equipment requirements | Identify equipment, condition, calibration, and verification ideas |
| Know time limits | Create memory prompts and practice the sequence under time pressure |
| Perform measurement | Practice the physical step with correct setup and reading discipline |
| Describe verbally | Build a clear spoken answer for sampling and allowed verbal tasks |
| Report result | Practice the final record step every time, not only on exam day |
The JTA also protects candidates from studying too broadly. ACI policy says questions about general concrete technology are not included on either examination. General background may help understanding, but it should not displace the methods and practices. If a study source spends most of its time on cement chemistry and ignores field procedures, it is not aligned with this certification.
A strong JTA workflow starts with the current program standard list. Work through C1064 temperature, C172 sampling, C143 slump, C138 density, C231 pressure air, C173 volumetric air, and C31 field specimens. For each one, mark the written concepts, the performance tasks, the equipment concerns, the timing requirements, and the reporting requirement.
Candidates should also use the JTA to connect written and performance preparation. A written question may test a step that also appears on the performance checklist. A performance mistake may begin as weak written understanding. The same source document can support both exams if you use it actively.
One practical method is the three-column JTA page. The first column is the JTA item. The second column is what you must know for a closed-book written question. The third column is what your hands, voice, or result sheet must do on the performance side. This turns a long list into a readiness tool.
The JTA is not the same as the full ASTM standards. It does not replace official technical language. It is the exam-facing map that tells you where to focus. Use it with CP-1 41st Edition and the official standards so that study time remains both current and targeted.
