Decoding AOS Orchid Awards: Understanding FCC, AM, HCC and the Point System

When visiting orchid exhibitions and sales events, you may notice flower tags with alphabetic abbreviations like "AM" or "FCC." These originate from the flower evaluation and awards system operated by the American Orchid Society (AOS). Unlike domestic orchid shows and competitions in Japan, this is a point-based international evaluation system. In this article, I'll explain how to interpret it.

AOS Evaluation: A 100-Point Scale System

The key characteristic of the AOS evaluation system is that flower quality is assessed using a 100-point scale. Judges score elements such as flower size, form regularity, color vibrancy and uniformity, and petal texture, with the total score determining the flower's level of excellence. In contrast to domestic Japanese orchid shows and competitions, which typically employ qualitative evaluations based on judges' overall impressions and plant presentation, the AOS system leaves a permanent record of results based on a clear numerical standard. Understanding this difference makes it much easier to interpret the meaning of evaluations written on foreign labels.

FCC, AM, and HCC: Three Levels of Grading

AOS flower grades have several levels corresponding to point scores. As a general guide, the highest award "FCC (First Class Certificate)" is roughly 90 points and above, the runner-up "AM (Award of Merit)" is roughly in the 80s, and "HCC (Highly Commended Certificate)" is roughly around 75–79 points. However, these point thresholds are merely rough guidelines, and for precise cutoffs and operational details, it's best to refer to the official AOS judging standards.

These grades function as a kind of "achievement certificate" showing how highly a particular flower was evaluated at the time of judging, and they remain recorded on pedigree tags and materials for orchids. They are often referenced as a quality indicator when breeders select the next cross-parents or when purchasers choose plants, and they carry practical significance beyond being merely a show result.

Awards for More Than Just Flowers

The AOS awards system does not evaluate only the quality of individual flowers. For instance, awards like the "CCM (Certificate of Cultural Merit)" are said to recognize the overall cultivation technique and plant presentation skill of specimens blooming profusely in a pot. Rather than evaluating the perfection of a single bloom, these awards are considered to assess the grower's management and cultivation skill over an extended period, and they serve as a significant source of encouragement. For the latest and most accurate information on the types and operational details of these awards, we recommend checking the official AOS standards.

The Practical Role of Awards

Award records are not merely a matter of past glory—"winning an impressive award back then." In genera like Dendrobium and Cymbidium, where hybridization is active, flowers with award histories are more likely to be selected as the next cross-parents, along with their offspring. For purchasers as well, the award record on a tag serves as a clue to understanding what lineage the plant belongs to.

If you understand that domestic Japanese orchid show judging is a qualitative system based on a holistic evaluation of flower appearance and plant health at the venue, whereas the AOS point system is an international evaluation standard based on quantified criteria, you can interpret the two without confusion. Neither is inherently superior; they simply have different evaluation characteristics—different measuring sticks, so to speak. It's helpful to keep this distinction in mind.

The Value of Understanding Tag Labels

Orchid catalogs from overseas nurseries and some imported labels carry AOS award notations. For example, grades and the abbreviated society name are typically written together in forms like "AM/AOS." Without knowing what this notation means, it looks like nothing more than random letters, but understanding the 100-point scale and grading system behind it provides a key to interpreting what evaluation history that flower's lineage carries. Of course, awards alone don't determine plant quality, but it's useful to understand this system as one reference for cultivation and hybridization.

Summary

The AOS grades such as FCC, AM, and HCC, as well as awards like CCM that recognize cultivation technique, are all long-established international evaluation standards used in the world of orchids. The fact that they are based on a clear numerical criterion distinguishes them from the qualitative judging of domestic Japanese orchid shows and competitions, and serves as a key to interpreting pedigree and tag evaluations. With this background in mind, when you look at an orchid tag, the evaluation history that the plant has accumulated may appear in a new light. At botachoku, growers throughout the country grow and sell orchids that you can purchase directly online, and we will continue to introduce the background of these evaluation systems in our columns.
