Exam Information

The Consolidated Exam Committee, established in 2006, has achieved the goal set by AOSA and SCST members of developing a single accreditation standard for conventional seed analysts in the United States by Spring 2013. The members of the AOSA Certification of Analysts Committee and SCST RST Board of Examiners combined the best aspects of both exams to develop germination and purity exams that will be offered annually in each region (as needed).  The germination and purity exams each take one day and include both written and practical exercises.
