Exams for the Ohio Certified Nursery Technician (OCNT) specializations are now offered monthly. (see dates below) The January testing is held in conjunction with the CENTS over a three-day period in Columbus, Ohio. Each specialization exam is offered on a different day. The Garden Center test is normally offered on Monday morning of the trade show, the Grower test on Tuesday morning, and the Landscape test on Wednesday morning.
The summer testing takes place during the month of August. The summer testing is offered on three separate days at three different locations throughout Ohio. A testing day is offered in conjunction with the Nursery Growers of Lake County Ohio Summer Field Day. The location for this field day varies year to year, but will always be located in northeastern Ohio. The additional testing locations are offered in Columbus, and Cincinnati. All three specialization exams are offered at different times of each of the three testing days. Dates, times, and locations for the three summer test days vary from year to year.
