Exam Information

The CCA Exam is now an internet-based exam, available four times throughout the year via a remote proctor. 

Exam Details: The CCA Exam is offered exclusively online, completed at the examinee's computer and monitored by a proctor via the examinee's webcam and microphone, with additional security features to protect the integrity of the exam. The exam can be taken 24 hours a day, including Saturday and Sunday during the quarterly window for testing, for which you will register and then schedule.

There are three steps to the testing process:

  1. Registration
    • Examinees must register for the exam during an Exam Registration window just prior to their preferred testing windows.
  2. Scheduling
    • Examinees must then schedule their specific exam time during the Exam Scheduling period.
  3. Exam Window
    • Examinees must complete testing at their scheduled time in that exam window.

Exam Prep: Ohio State University Extension will offer an in-person CCA Exam Preparation Course January 10-11, 2024, in Sidney, Ohio. This course will provide an overview of the CCA program, and help you prepare for the exams by covering basic principles in the four competency areas – nutrient management, soil and water management, pest management, and crop management. Even if you are not considering the CCA program, this class is a great basic agronomy course that any farmer, ag retailer, or anyone working with field crops will find valuable. Additional information on this prep course and respective registration can be found here: https://bit.ly/OSU-CCAEXAMPREP-2024.

Starting with the March-April window in 2024, examinees will have the option of completing their ICCA and Local Board Exams one section at a time. This means that they can take Nutrient Management, Soil and Water Management, Pest Management, and Crop Management separately thereby being able to study for and take the test for one subject at a time. Examinees choosing this option will have one year to finish all four sections of the exam they choose to take this way. More than one section can be taken in any given exam window.

Tri-State Performance Objectives

The Certified Crop Adviser (CCA) Program is an educational program with two main goals: to certify individuals who have passed a minimum competency examination and to establish a mechanism of continuing education for those already certified.

Technical Service Provider Program (TSP)

Technical service providers (TSPs) offer services to agricultural producers such as farmers, ranchers, and private forest landowners on behalf of the Natural Resources Conservation Service (NRCS). TSPs help these producers plan, design, and implement conservation practices or develop conservation activity plans to improve agricultural operations.

American Society of Agronomy

The American Society of Agronomy (ASA) is a progressive international scientific and professional society that empowers scientists, educators, and practitioners in developing, disseminating, and applying agronomic solutions to feed and sustain the world.

Ohio Certified Crop Adviser of the Year Award

The Ohio Certified Crop Adviser of the Year award was designed to recognize individuals who are highly motivated, deliver exceptional customer service for farmer clients in nutrient management, soil and water management, integrated pest management and crop production and have contributed substantially to the exchange of ideas and the transfer of agronomic knowledge within the agricultural industry in Ohio.
