2026 Field 1 Scheduling Changes:

In an effort to more efficiently utilize our Supplemental Examiners, the CRMCA has changed how some ACI Exam Sessions will be scheduled in 2026. 2026 will have fewer overall exam dates but greater overall capacity so we can accommodate more registrants than ever before.

Staggered Start Sessions
Field 1 exams at the Denver location will follow a staggered start schedule. These sessions will be split into two Blocks:

• Block A
  • Start Time: 7:30am
  • Capacity: 15
  • Full Exam Registrations: We ask that examinees seeking RECERTIFICATION register for Block A
  • Retest Registrations: Written Retests Only
• Block B
  • Start Time: 10:30am
  • Capacity: 30
  • Full Exam Registrations: We ask that examinees seeking certification for the FIRST-TIME register for Block B
  • Retest Registrations: Performance Retests Only

2026 Field 1 Exam Dates [Not Yet Open for Registration]:

PLEASE NOTE: While we do aim to open registrations at the start of the day they’re scheduled to be opened, there may be times where this isn’t possible and registration won’t open until later in the day. This is most likely to happen when the date falls on a Monday or immediately after a Holiday or large CRMCA event. We appreciate your patience and understanding when these situations arise.

*This is the anticipated schedule for 2026. Dates and locations are not expected to change, but may be adjusted if needed.*

Certification Requirements:

ACI will grant certification only to those applicants who meet both of the following requirements:

1. A passing grade on the ACI written examination; AND
2. Successful completion of the ACI performance examination.

The one-hour written examination is closed-book and consists of 55 multiple-choice questions. There are between five and ten questions on each of the ASTM test methods and practices. To pass the written examination, BOTH of the following conditions must be met:

1. At least 60% correct for each of the required test methods and practices; AND
2. A minimum score of 70% overall.

The performance examination is also “closed book” and requires actual demonstration of six of the required test methods and practices plus a verbal description of Practice C172/C172M (sampling). The examinee is judged on his/her ability to correctly perform (or describe, where allowed) all of the required steps for each procedure.

Certification is valid for a period of five years from the date of successfully completing all requirements. Recertification requires successful completion of both the written and performance examinations.
