1.5 Current Study Sources and CP-1 41st Edition

Source Control for Current ACI Facts

Good preparation starts with current source control. ACI's current program page lists the program resources as ASTM C1064/C1064M-23, C172/C172M-17, C143/C143M-20, C138/C138M-23, C231/C231M-24, C173/C173M-24, and C31/C31M-24. Those editions should drive the current study plan unless ACI updates its official page again.

ACI's current bookstore page for CP-1 identifies CP-1, 41st Edition, Technician Workbook for Concrete Field Testing Technician Grade I. The product page lists publication year 2025. It describes the workbook as containing program information, study questions, sample checklists, and a practice exam, with the program based on the current standards named on that page.

One fact needs special attention: the CP-1 41st Edition product page states that the ASTM standards are not included in the workbook. Candidates should not repeat older claims from past editions or old preparation packages. CP-1 is a study workbook, not a replacement for the separate ASTM standards.

The current standard list matters because small edition changes can affect what a candidate sees in study material. A candidate using an old workbook, old handout, or old web page may see older standard or workbook references references. Those may have been current in the past, but this guide is using the current ACI program page and CP-1 41st Edition facts for the May 6, 2026 content update.

Avoid another source-control trap: confusing bookstore prices with exam fees. ACI's bookstore page may show a current printed workbook price and member price. Those are product prices for a study material purchase at that time. They are not nationwide ACI certification exam fees and should not be published as such.

The JTA is especially valuable because it tells candidates what kind of knowledge and performance tasks may be assessed. It separates general concepts from specific procedures or values, and it indicates where tasks may be performed or verbally described. Use the JTA as a checklist for readiness, not as casual background reading.

A practical source stack looks like this. Start with the current ACI program page to confirm what certification requires. Read the policy to understand written scoring, performance exam rules, trial handling, and recertification. Use the JTA to map study objectives. Use CP-1 41st Edition for guided learning and practice questions. Use the official ASTM standards for authoritative technical language when you need exact procedure requirements.

The goal is not to collect every document and then feel overwhelmed. The goal is to know which document answers which question. If the question is about certification validity, use ACI policy. If the question is about study workbook contents, use the CP-1 product page. If the question is about a technical step, use the relevant ASTM standard and the JTA.
