CP-1, JTA, and Source Control
Key Takeaways
- Use current ACI sources first, including the official program page, the certification policy, the Job Task Analysis, and CP-1 41st edition.
- CP-1 41st edition provides program information, instructional material, study questions, sample checklists, a practice exam, the JTA, and supplemental documents.
- The ASTM standards are not included in CP-1, so candidates should not assume the workbook replaces authorized ASTM standards.
- Source control prevents outdated edition errors, especially for current ASTM designations and performance-exam format.
Keep Your Final Review Tied to Current Official Sources
Source control is a real exam strategy. ACI Field Testing Grade I has stable core concepts, but editions, program pages, and policy documents can change. The current source brief points candidates to the official ACI program page, the ACI Job Task Analysis, the ACI Certification Program Policy for Concrete Field Testing Technician Grade I, and CP-1, 41st edition. Use those before relying on old handouts or search results.
CP-1 is especially useful because it is built for this certification program. The current ACI store page identifies CP-1, 41st edition, with publication year 2025. ACI says CP-1 contains program information, instructional material, technical sections, study questions, sample checklists, a practice exam, the JTA, and supplemental documents. Those resources are well matched to written review and performance practice.
Do not misunderstand what CP-1 contains. ACI says the ASTM standards are not included in CP-1. That means CP-1 can guide your study, but it is not a substitute for authorized ASTM standards when exact standard language is needed. The final review should respect that distinction. Use CP-1 and the JTA to organize learning, and use official ASTM sources through legitimate access when exact procedural text must be checked.
| Source | Best use in final review | Common mistake to avoid |
|---|---|---|
| ACI official program page | Confirm current exam scope and listed standards | Using an old page or unofficial summary as controlling policy |
| ACI certification policy | Confirm certification, validity, and recertification requirements | Assuming continuing education by itself renews this certification |
| ACI Job Task Analysis | Map knowledge and performance tasks | Treating the JTA as optional because it is short |
| CP-1 41st edition | Study explanations, questions, checklists, practice exam, and JTA | Saying CP-1 contains full ASTM standards |
| Current ASTM standards | Confirm exact method requirements through authorized access | Quoting old editions or relying on field shortcuts |
| Personal error log | Target final remediation | Rewriting notes without checking actual misses |
The current ACI program standard list in the source brief includes C1064/C1064M-23, C172/C172M-17, C143/C143M-20, C138/C138M-23, C231/C231M-24, C173/C173M-24, and C31/C31M-24. Those designations matter for source awareness. Do not use older CP-1 editions or older ASTM editions as your final authority when current sources are available.
The JTA is a compact map of what the certified technician is expected to know and do. In final review, use it as a coverage checklist. For each method, ask whether you can explain the purpose, identify apparatus, perform or describe key tasks, recognize validity problems, and record results. Then connect those tasks to CP-1 practice questions and sample performance checklists.
Source control also protects performance expectations. A frequent bad summary says the performance exam has six demonstrations with a C172 verbal sampling component. The current ACI framing is six demonstrations plus verbal description of C172 sampling. That difference changes how you practice. If your study source gets that wrong, check the rest of it carefully.
The best final source stack is simple: official ACI program facts for certification rules, CP-1 for guided study, the JTA for task coverage, authorized ASTM standards for exact procedures, and your own error log for personal risk.
