Students must attend both the training and testing portion of a class to receive CTTP certification.

Contractors may register online or by filling out a registration form and sending it to CTTP by fax or email. The online registration form is available on the CTTP Course Registration Page. To obtain a printed registration form, you may print it from the website, or you can call the CTTP offices at 479-575-3997.

AHTD employees must contact Dorothy Rhodes at to register for a class. Once you have been selected for a course, you will receive an email containing instructions for the class.

A confirmation email is sent after an online registration has been received (usually within 3 days). If you register by a method other than online, you will receive a letter in the mail confirming your registration. You may call (479-575-3997) or email us at at any time to confirm your reservation in a class.

Complete the registration form, and select ‘on Next Available Date’ for the class that you would like to take under Course Requested Heading. Then, add any additional information concerning your request in the Comments box. CTTP maintains a waiting list for each course, and we will contact you when a space becomes available. When the waiting list becomes full, a new class will be added.

In most cases, the course calendar is set approximately 3 months prior to the course date. In some cases, schedule changes become necessary, or additional classes are added. Be sure to check the CTTP website for changes.

Course fees vary by class. A Fee Schedule is available on our website.

Payment must be in the form of a check or money order, made payable to the ‘University of Arkansas – CTTP’ and annotated to indicate the purpose of the payment (i.e., student name(s) and course title(s)). Payment is collected on the first day of class.

First, check the CTTP Course Descriptions for a listing of the specifications covered in each course. You may also visit the Online Training section of the CTTP website to view the online training materials currently offered. CTTP courses are not intended to provide basic training, but rather to serve as a refresher and evaluation, leading to certification. Before coming to class, participants should have a working knowledge of the test methods, as well as the math required for the necessary calculations. Laboratory experience with the test methods will help tremendously.

Also, check our website for lodging suggestions and maps.

Items to Bring:

You will need to bring a handheld calculator; we will provide all other training materials.
Please be aware that the use of tobacco products is prohibited on all University of Arkansas properties, and that CTTP requires long pants and closed-toe shoes in the laboratory.

Online modules are currently available at at CTTP Online for the Basic Aggregates and Concrete Field Testing course along with Basic Math modules for Aggregates, Concrete, Soils and Asphalt . Similar modules will be developed in the future. Check our website for updates.

Pre-requisites vary by class. The Basic Aggregates course is a pre-requisite for the Concrete Field Testing Technician, Hot Mix Asphalt Testing Technician, Soil Testing Technician, and Concrete Strength Testing Technician courses. Beginning January 1, 2017, dosimeter badges will no longer be required for attending CTTP classes.

If your company is not required to use a dosimeter, then you must provide a copy of a letter from the Arkansas Department of Health (ADH) stating the exemption. The letter must include the company name for which the exemption applies.

Beginning January 1, 2017, dosimeter badges will no longer be required for attending CTTP classes.

It is recommended that you bring a handheld calculator to all classes. CTTP has calculators available, and you may borrow one for the class; however, most students are more comfortable using one that they are familiar with. You may also want to bring a straightedge or ruler.

Safety is the most important consideration regarding dress. CTTP requires that each person wear applicable personal protective equipment in the laboratory. This includes long pants, closed-toe shoes, and safety glasses. Gloves are also necessary for some classes. Safety glass, gloves, and other personal protective equipment may be borrowed from CTTP during the class. Keep in mind that your clothes may get dirty while working in the lab.

The CTTP classroom is located in the central portion of the University of Arkansas’ Engineering Research Center in Fayetteville, Arkansas. Maps and directions are available on our website.

A listing of some local Hotels is available on our website.

Effective July 1, 2008, smoking and the use of tobacco products (including cigarettes, cigars, pipes, smokeless tobacco, and other tobacco products) by students, faculty, staff, and visitors are prohibited on all University of Arkansas properties.

Within approximately one week of the exam, results will be posted on the listing of Certified Technicians page on the CTTP website. To view your certifications, enter your name in the search box, and your CTTP certifications will be shown along with the corresponding expiration date. An updated expiration date indicates a passing grade in the course.

Approximately one week after the exam, an email is sent to all class participants. The exam score is contained in the email for each participant who passed the course. This will be followed by a course completion letter, certificate and pocket card by regular mail. Unsuccessful participants will receive a letter with course results. Exam results for Concrete Field Testing Technician and Concrete Strength Testing Technician courses may take as long as 3 weeks because the exams are graded by the American Concrete Institute. ACI exam scores will be mailed to you directly from ACI. CTTP certificates and pocket cards will be sent separately from CTTP.

Certification periods vary by class. Please refer to the Course Descriptions for individual course details. Certifications in Basic Aggregates, Hot Mix Asphalt, Soils, NPDES, and Roadway Construction Control expire on either June 30, or December 31, after the designated certification period. Certifications based on ACI exams expire on the date concurring with the ACI expiration date.

You must pass both the written and performance components of each course in order to receive a passing grade. Re-testing policies vary by course. For Basic Aggregates, Hot Mix Asphalt, Soil and Aggregate, NPDES, and Roadway Construction Control, the entire course must be repeated. For courses utilizing ACI exams (Concrete Field Testing Technician and Concrete Strength Testing Technician), only the portion failed (written or performance) must be repeated – subject to ACI guidelines. Thus, for these courses a student may choose to test only. However, the re-testing success rate is much higher for those who choose to repeat the entire class than those who simply take the test again.

Replacement pocket cards are available for $25. Please submit a Online Pocket Card Reqest if you need a replacement card.

No. You must first complete the Basic Aggregates course, which is a pre-requisite to the Concrete Field Testing Technician and Concrete Strength testing courses. CTTP will accept ACI certifications granted through other programs, but you must notify us so that we can verify certification and include it on your CTTP pocket card.

If you completed ACI certification through a program other than CTTP AND you have successfully completed the CTTP Basic Aggregates course, we will add your concrete certification to your pocket card. Please inform us of any ACI certifications that you hold when you come to class. If you inform us at a later date, you will be charged $25 for a replacement pocket card.

CTTP does grant reciprocal certification for ACI (American Concrete Institute) certifications. The Basic Aggregates, Hot Mix Asphalt, Soils, and NPDES courses are specific to the state of Arkansas, and contain components that may not be included in certifications from other states. Requests for reciprocity will be reviewed on a case by case basis, and will generally only be granted if a) all specifications required for CTTP certification are covered under the certification for the other state, and b) a closed book written exam and an individual performance exam have been successfully completed.

No. All written exams are closed-book and closed-notes, with the exception of the Roadway Construction Control exam. During performance exams you may refer to your books and notes between exam stations, but not while testing.

No. You must attend the entire class in order to test for certification. (Extenuating circumstances will be reviewed on a case-by-case basis.)

No. You must have a dosimeter in order to test in the Hot Mix Asphalt and Soil and Aggregate Testing Technician courses.
