Hardened Concrete Properties

The CIT Program provides the following methods for obtaining certification.

1. Hardened Concrete Properties Course

Online course - course is online and available upon registration. The course is available to you year round with the course period designated in your registration confirmation email and the CanvasPro course page. You must complete the course and subsequent exam(s) by the stated completion date in your confirmation email and in CanvasPro. Written and performance exams are administered in Salina, KS.

In Person course - three day course instructed in Salina, KS and written and performance exams are administered on the last day.

Prerequisite: Pass Basic Math test prior to enrolling for the course.

2. Hardened Concrete Properties Provisional Online Class & Exam

This option is for newly hired individuals who need this provisional certification to do hardened concrete properties testing over the summer months. The performance exam will need to be completed within the upcoming training season or within one year, whichever comes first. The performance exam must be completed at K-State Salina. Once the written and performance exams have been completed, the certification will start on the date of the written exam, not the performance exam. The written exam is administered online at the student’s location and requires a supervisor or supervisor approved proctor. This option is not available for recertification.

Testing Information

• Exam: This class and quiz-out options require a written exam and a performance exam. The exam with IA Witness option requires a written exam.
• Score: A score of 60% on each portion of the written exam plus a 70% overall score is required to pass the exam. Failure on any part of the written exam requires a full retest. If three or less performance subtests are failed, only the subtest failed must be retaken. If four or more subtests are failed, all performance subtests must be retaken.
