Aggregate Field Tester Class (AGF)

The CIT Program provides the following methods for obtaining certification:

1. Register for the Aggregate Field class and pass the written and performance exams.
Prerequisite: Pass Basic Math test at least 30 days prior to enrolled class date.

2. Register for the Aggregate Field Quiz Out/Recertification and pass the written and performance exams. The Quiz Out/Recertification option allows a person to take the written and performance exams for initial certification or for recertification without attending class. If this option is chosen, the individual is expressing their knowledge and ability to perform test procedures without coaching. This option is recommended for individuals who have at least five years experience. The Aggregate Field class book will be mailed to the address on the registration.

3. Register for the Aggregate Field Exam with IA Witness option and pass the written exam. This option is for individuals who have been IA witnessed and only need to take the written exam. You must submit the DTMT 296 screen print from CMS indicating that KT-1, KT-2, KT-3, KT-11 & KT-50 have been witnessed, to the K-State Salina CIT Program Office. The Aggregate Field class book will be mailed to the address on the registration.
